Wednesday

Wednesday was both Mata and Adam's day off. While the latter spend his morning studying, as usual, Mata went to the town's arcade. It was a funky joint, located in the old walls of a castle. Mata didn't meet anybody interesting, except for a man in a topper that clearly cheated at playing cards.

When she was back home, Mata convinced Dr. Splitter to go out with her for some hours. They went on a walk and arrived at the old abandoned factory.

Both of them were curious and so they went inside, where nobody but the two of them were.

One thing let to another and so they didn't use the old photo booth to take any pictures.

Back at home, Mata was a little worried, when she noticed that Dr. Splitter felt comfortable enough around her now, to walk around in his underwear. Mata: Adam, I hope we can agree on, that Steve must not know about this, right? Adam: O-of course Mata. Everything went so fast between us, I don't think he would understand. I-I'll give you two the space you need. That was good to know. Mata got into the shower and when she took out the trash later, she found a cute ginger cat by the can.

Mata: Aww, aren't you just the cutest lil thing?

Mata and Steve weren't the only animal lovers in the household. But while their affection mostly focused on stray cats, Adam had a specific idea of the pet they should get.

Quantum interference in the service of information technology

Credit: CC0 Public Domain

Researchers from the Professors of Physics, University of Warsaw, in partnership with the University of Oxford and NIST, have actually revealed that quantum interference makes it possible for processing of big sets of information much faster and more precisely than with basic approaches. Their research studies might enhance applications of quantum innovations in expert system, robotics and medical diagnostics, for instance. The outcomes of this work have actually been released in Science Advances.

Contemporary science, medication, engineering and information technology need effective processing of information—still images, noise and radio signals, along with information originating from various sensing units and video cameras. Given That the 1970s, this has actually been accomplished by methods of the Quick Fourier Transform algorithm (FFT). The FFT makes it possible to effectively compress and transfer information, shop photos, broadcast digital TELEVISION, and talk over a smart phone. Without this algorithm, medical imaging systems based upon magnetic resonance or ultrasound would not have actually been established. Nevertheless, it is still too sluggish for numerous requiring applications.

To fulfill this objective, researchers have actually been pursuing years to harness quantum mechanics. This resulted in the advancement of a quantum equivalent of the FFT, the Quantum Fourier Transform (QFT), which can be recognized with a quantum computer system. As the quantum computer system at the same time processes all possible worths (so-called “superpositions”) of input information, the number of operations reduces substantially.

In spite of the fast advancement of quantum computing, there is a relative stagnancy in the field of quantum algorithms. Now researchers have actually revealed that this outcome can be enhanced, and in a rather unexpected method.

Kravchuk change

Mathematics explains numerous changes. One of them is a Kravchuk change. It is extremely comparable to the FFT, as it enables processing of discrete (e.g. digital) information, however utilizes Kravchuk operates to decay the input series into the spectrum. At the end of the 1990s, the Kravchuk change was “rediscovered” in computer system science. It ended up being exceptional for image and noise processing. It permitted researchers to establish brand-new and a lot more accurate algorithms for the acknowledgment of printed and handwritten text (consisting of even the Chinese language), gestures, indication language, individuals, and deals with. A lots years earlier, it was revealed that this change is perfect for processing low-grade, loud and distorted information, and therefore it might be utilized for computer system vision in robotics and self-governing lorries. There is no quick algorithm to calculate this change, however it ends up that quantum mechanics enables one to prevent this restriction.

“Holy Grail” of computer system science

In their short article released in Science Advances, researchers from the University of Warsaw—Dr. Magdalena Stobinska and Dr. Adam Buraczewski, researchers from the University of Oxford, and NIST, have actually revealed that the easiest quantum gate, which interferes in between 2 quantum states, basically calculates the Kravchuk change. Such a gate might be a widely known optical gadget—a beam splitter, which divides photons in between 2 outputs. When 2 states of quantum light enter its input ports from 2 sides, they interfere. For instance, 2 similar photons, which at the same time enter this gadget, lot into sets and come out together by the very same exit port. This is the popular Hong-Ou-Mandel result, which can likewise be reached states made of numerous particles. By interfering “packets” consisting of numerous identical photons (indistinguishability is extremely essential, as its lack ruins the quantum result), which encode the information, one gets a specialized quantum computer system that calculates the Kravchuk change.

The experiment was carried out in a quantum optical lab at the Department of Physics at the University of Oxford, where an unique setup was constructed to produce multiphoton quantum states, so-called Fock states. This lab is geared up with TES (Transmission Edge Sensors), established by NIST, which run at near-absolute absolutely no temperature levels. These detectors have a unique function: they can really count photons. This enables one to specifically check out the quantum state leaving the beam splitter and therefore, the result of the calculation. Most notably, such a calculation of the quantum Kravchuk change constantly takes the very same time, regardless of the size of the input information set. It is the “Holy Grail” of computer system science: an algorithm consisting of simply one operation, carried out with a single gate. Obviously, in order to get the result in practice, one requires to carry out the experiment numerous hundred times to get the stats. This is how every quantum computer system works. Nevertheless, it does not take long, since the laser produces lots of millions of multiphoton “packets” per second.

The outcome acquired by researchers from Poland, the UK and the United States will discover applications in the advancement of brand-new quantum innovations and quantum algorithms. Its variety of utilizes surpass quantum photonics, because a comparable quantum interference can be observed in various quantum systems. The University of Warsaw requested a global patent for this development. The researchers hope that the Kravchuk change will quickly discover usage in quantum calculation, where it will end up being a part of brand-new algorithms, specifically in hybrid quantum-classical computer systems that combine quantum circuits with “normal” digital designs.

Quantum interference in the service of information technology

Scientists from the Faculty of Physics, University of Warsaw, in collaboration with the University of Oxford and NIST, have shown that quantum interference enables processing of large sets of data faster and more accurately than with standard methods. Their studies may boost applications of quantum technologies in artificial intelligence, robotics and medical diagnostics, for example. The results of this work have been published in Science Advances.

Contemporary science, medicine, engineering and information technology demand efficient processing of data—still images, sound and radio signals, as well as information coming from different sensors and cameras. Since the 1970s, this has been achieved by means of the Fast Fourier Transform algorithm (FFT). The FFT makes it possible to efficiently compress and transmit data, store pictures, broadcast digital TV, and talk over a mobile phone. Without this algorithm, medical imaging systems based on magnetic resonance or ultrasound would not have been developed. However, it is still too slow for many demanding applications.

To meet this goal, scientists have been trying for years to harness quantum mechanics. This resulted in the development of a quantum counterpart of the FFT, the Quantum Fourier Transform (QFT), which can be realized with a quantum computer. As the quantum computer simultaneously processes all possible values (so-called “superpositions”) of input data, the number of operations decreases considerably.

In spite of the rapid development of quantum computing, there is a relative stagnation in the field of quantum algorithms. Now scientists have shown that this result can be improved, and in a rather surprising way.

Kravchuk transform

Mathematics describes many transforms. One of them is a Kravchuk transform. It is very similar to the FFT, as it allows processing of discrete (e.g. digital) data, but uses Kravchuk functions to decompose the input sequence into the spectrum. At the end of the 1990s, the Kravchuk transform was “rediscovered” in computer science. It turned out to be excellent for image and sound processing. It allowed scientists to develop new and much more precise algorithms for the recognition of printed and handwritten text (including even the Chinese language), gestures, sign language, people, and faces. A dozen years ago, it was shown that this transform is ideal for processing low-quality, noisy and distorted data, and thus it could be used for computer vision in robotics and autonomous vehicles. There is no fast algorithm to compute this transform, but it turns out that quantum mechanics allows one to circumvent this limitation.

“Holy Grail” of computer science

In their article published in Science Advances, scientists from the University of Warsaw—Dr. Magdalena Stobinska and Dr. Adam Buraczewski, scientists from the University of Oxford, and NIST, have shown that the simplest quantum gate, which interferes between two quantum states, essentially computes the Kravchuk transform. Such a gate could be a well-known optical device—a beam splitter, which divides photons between two outputs. When two states of quantum light enter its input ports from two sides, they interfere. For example, two identical photons, which simultaneously enter this device, bunch into pairs and come out together by the same exit port. This is the well-known Hong-Ou-Mandel effect, which can also be extended to states made of many particles. By interfering “packets” consisting of many indistinguishable photons (indistinguishability is very important, as its absence destroys the quantum effect), which encode the information, one obtains a specialized quantum computer that computes the Kravchuk transform.

The experiment was performed in a quantum optical laboratory at the Department of Physics at the University of Oxford, where a special setup was built to produce multiphoton quantum states, so-called Fock states. This laboratory is equipped with TES (Transmission Edge Sensors), developed by NIST, which operate at near-absolute zero temperatures. These detectors possess a unique feature: they can actually count photons. This allows one to precisely read the quantum state leaving the beam splitter and thus, the result of the computation. Most importantly, such a computation of the quantum Kravchuk transform always takes the same time, regardless of the size of the input data set. It is the “Holy Grail” of computer science: an algorithm consisting of just one operation, implemented with a single gate. Of course, in order to obtain the result in practice, one needs to perform the experiment several hundred times to get the statistics. This is how every quantum computer works. However, it does not take long, because the laser produces dozens of millions of multiphoton “packets” per second.

The result obtained by scientists from Poland, the United Kingdom and the United States will find applications in the development of new quantum technologies and quantum algorithms. Its range of uses go beyond quantum photonics, since a similar quantum interference can be observed in many different quantum systems. The University of Warsaw applied for an international patent for this innovation. The scientists hope that the Kravchuk transform will soon find use in quantum computation, where it will become a component of new algorithms, especially in hybrid quantum-classical computers that merge quantum circuits with “normal” digital layouts.

Monday

As it was their moving day, Steve was allowed to stay at home from school so he could spend the whole morning playing his favorite video game. Dr. Splitter's engine was really great, not to compare to the run-down they owned when they still lived with Dad.

Mata: Oh, I see you're pursuing your creative streak, Dr. Splitter. It's so important to train all the fields a Sim could gain skills in. Adam: Oh, you-you think so, Mrs. Dore? I don-don't know, I-I'm still a beginner in the creative field. Um.. wou-would you... I mean... don't you mind talking to me as... as lightly dressed as... Mata: *laughs* Ah, Dr. Splitter, I don't mind at all. And a man of your standing shouldn't mind too. I'm positive, I've seen enough women like me. Adam didn't know what to say. He never had seen a woman like Mata. A distant memory of taking baths with his mother came to his mind, she was the only woman he'd ever seen in less than a lab coat. They chit-chatted for some more and suddenly Mata pulled him into a tender hug. Mata: Thank you again for letting us stay with you, Adam. He had never heard his name be spoken like this.

Mata sprung away from Dr. Splitter when she heard the door open. Steve: Mom! Can you believe it?! I made a new high score! Without all the lag I'm really great at SSX3!

Around lunch time, some neighbors came over to meet the new inhabitants of Emerald Heighs. Claire Voyante was the leader of a girls group home, April DeShong a local housewife and Rocky Stone the co-founder of a local interest group. They had a nice day and Steve could show off his SSX3 skills.

Steven knew that his mother wanted him to go to college as soon as he was old enough but Steven didn't know if he really wanted to go. Being new in town was hard enough, wouldn't it be even harder to leave right away again and start over AGAIN?

[tamtam-go92]

Our next step is with one of the more scientific areas of Emerald Heights, near the ominous oil field...

Splitter:

Dr. Adam Splitter has been living on Foundation property so he could monitor all his delicate experiments 24/7 for years, but now the Foundation has saddled him with an assistant! And she comes with a teen-age boy in tow. Can they adjust to life with the renowned reclusive scientist? Or will they all make each other Mad?

He lives across from the Science Center so he can monitor experiments at all hours, and has done so for years; but you blow up one lab, one time, just once, and suddenly they're all over you threatening to cut off the grant money if you don't get a younger assistant. And technically the house belongs to the Foundation so the board can move in whoever they want.

Dr. Adam Splitter: male, elder, Sim Knowledge/Fortune (Max out 7 Skills) Virgo (10/0/8/7/0) Science career, OTH: Sports Traits: Neat, Brooding, Vehicle Enthusiast, Computer Whiz, Materialistic

After her divorce, she'd been worried about making ends meet, but she's been so lucky! Not only does she get to work personally with the great Dr. Splitter, but she and her boy Steve get free housing! Okay, it's a little cramped; but she's far away from all the humiliating scenes of her marriage and that covers a multitude of sins. Steve's pouting, but he'll pull it together. He's a good boy, really.

Mata Dore: female, adult, Sim Knowledge/Family (Max out 7 Skills) Cancer (5/5/5/5/5) Science career, OTH: Sports Traits: Disciplined, Friendly, Match Enthusiast, Genius, Nurturing

The divorce is a bummer, the move is a bummer, sharing a room with his mother and his house with a crabby senile dude (Assistant, yeah right, try babysitter, Mom doesn't know when she's being exploited) is a megabummer. On the bright side, though - that house out back is crawling with hot teenage girls! So maybe it won't be that bad.

Quantum interference in the service of information technology

Scientists from the Faculty of Physics, University of Warsaw, in collaboration with the University of Oxford and NIST, have shown that quantum interference enables processing of large sets of data faster and more accurately than with standard methods. Their studies may boost applications of quantum technologies in artificial intelligence, robotics and medical diagnostics, for example. The results of this work have been published in Science Advances.

Contemporary science, medicine, engineering and information technology demand efficient processing of data—still images, sound and radio signals, as well as information coming from different sensors and cameras. Since the 1970s, this has been achieved by means of the Fast Fourier Transform algorithm (FFT). The FFT makes it possible to efficiently compress and transmit data, store pictures, broadcast digital TV, and talk over a mobile phone. Without this algorithm, medical imaging systems based on magnetic resonance or ultrasound would not have been developed. However, it is still too slow for many demanding applications.

To meet this goal, scientists have been trying for years to harness quantum mechanics. This resulted in the development of a quantum counterpart of the FFT, the Quantum Fourier Transform (QFT), which can be realized with a quantum computer. As the quantum computer simultaneously processes all possible values (so-called “superpositions”) of input data, the number of operations decreases considerably.

In spite of the rapid development of quantum computing, there is a relative stagnation in the field of quantum algorithms. Now scientists have shown that this result can be improved, and in a rather surprising way.

Kravchuk transform

Mathematics describes many transforms. One of them is a Kravchuk transform. It is very similar to the FFT, as it allows processing of discrete (e.g. digital) data, but uses Kravchuk functions to decompose the input sequence into the spectrum. At the end of the 1990s, the Kravchuk transform was “rediscovered” in computer science. It turned out to be excellent for image and sound processing. It allowed scientists to develop new and much more precise algorithms for the recognition of printed and handwritten text (including even the Chinese language), gestures, sign language, people, and faces. A dozen years ago, it was shown that this transform is ideal for processing low-quality, noisy and distorted data, and thus it could be used for computer vision in robotics and autonomous vehicles. There is no fast algorithm to compute this transform, but it turns out that quantum mechanics allows one to circumvent this limitation.

“Holy Grail” of computer science

In their article published in Science Advances, scientists from the University of Warsaw—Dr. Magdalena Stobinska and Dr. Adam Buraczewski, scientists from the University of Oxford, and NIST, have shown that the simplest quantum gate, which interferes between two quantum states, essentially computes the Kravchuk transform. Such a gate could be a well-known optical device—a beam splitter, which divides photons between two outputs. When two states of quantum light enter its input ports from two sides, they interfere. For example, two identical photons, which simultaneously enter this device, bunch into pairs and come out together by the same exit port. This is the well-known Hong-Ou-Mandel effect, which can also be extended to states made of many particles. By interfering “packets” consisting of many indistinguishable photons (indistinguishability is very important, as its absence destroys the quantum effect), which encode the information, one obtains a specialized quantum computer that computes the Kravchuk transform.

The experiment was performed in a quantum optical laboratory at the Department of Physics at the University of Oxford, where a special setup was built to produce multiphoton quantum states, so-called Fock states. This laboratory is equipped with TES (Transmission Edge Sensors), developed by NIST, which operate at near-absolute zero temperatures. These detectors possess a unique feature: they can actually count photons. This allows one to precisely read the quantum state leaving the beam splitter and thus, the result of the computation. Most importantly, such a computation of the quantum Kravchuk transform always takes the same time, regardless of the size of the input data set. It is the “Holy Grail” of computer science: an algorithm consisting of just one operation, implemented with a single gate. Of course, in order to obtain the result in practice, one needs to perform the experiment several hundred times to get the statistics. This is how every quantum computer works. However, it does not take long, because the laser produces dozens of millions of multiphoton “packets” per second.

The result obtained by scientists from Poland, the United Kingdom and the United States will find applications in the development of new quantum technologies and quantum algorithms. Its range of uses go beyond quantum photonics, since a similar quantum interference can be observed in many different quantum systems. The University of Warsaw applied for an international patent for this innovation. The scientists hope that the Kravchuk transform will soon find use in quantum computation, where it will become a component of new algorithms, especially in hybrid quantum-classical computers that merge quantum circuits with “normal” digital layouts.
