Free Space Optical Communication in Satellite-Based QKD

System Architecture and Performance Limits for Satellite Quantum Key Distribution

The major theme of the essay is  quantum key distribution (QKD), which satellite-based systems need for unconditionally secure communication. It highlights the engineering challenges of adopting QKD globally by lowering photon loss, beam divergence, and targeting mistakes in free space optical Communication systems. Research on precise channel modelling and practical implementation, including using UAVs as relays, aims to overcome these limitations. Interdisciplinary knowledge from optical engineering to quantum physics is needed to construct secure communication networks. Current research aims to increase system performance and develop trustworthy quantum communication technologies.

Quantum key distribution (QKD) secures communication during cyberattacks. QKD uses quantum mechanics for security, unlike classical encryption, which involves complex arithmetic that supercomputers can decipher. Although QKD systems are getting better in fibre optic and terrestrial labs, satellites are needed for worldwide deployments, which poses engineering hurdles.

Overcoming Physical Barriers for Global Reach

Physical implementation, especially satellite deployment and free space optical communication, is the present focus of quantum key distribution. Researchers strive to overcome major challenges to safe quantum communications across long distances. Background noise and photon loss from atmospheric turbulence, beam divergence, and poor aiming are issues. All of these elements can considerably increase QBER and decrease key generation rate.

Entanglement-based QKD protocols like E91 and BBM92 for satellite-to-satellite communications are intriguing. Two distant satellites, Alice and Bob, could receive qubits from a central entangled photon, enabling global key sharing without trusted nodes. The extremely low key generation rate and QBER elevation make long-distance deployment of these protocols difficult.

QKD's present trajectory requires free-space optical (FSO) communication, which uses light to carry data over the atmosphere or space, especially for secure quantum networks over long distances. It supports satellite-based quantum communication networks, which are necessary for worldwide quantum security.

Understanding QKD Free Space Optical Communication FSO communication involves delivering modified light beams from lasers to a receiver via air, dust, or water. QKD relies on FSO links to deliver quantum keys remotely without fibre optic cables. This is crucial for satellite-to-ground communications and intersatellite communication, since terrestrial fibre networks are impractical. Because QKD uses quantum physics rather than computational complexity to guarantee unconditionally secure communication, robust FSO networks are crucial.

FSO QKD's Main Issues

FSO communication for QKD is promising but challenging to execute, especially for long-distance satellite-to-satellite or satellite-to-ground links. Researchers seek to build safe quantum networks despite these issues. The main hurdles that slow key generation and increase QBER are:

Photon Loss: Signal photons may be lost on the FSO link for several causes. QKD relies on photon detection, hence this is a major challenge.

Divergence: Light beams expand naturally. Divergence reduces photons reaching the receiver, limiting signal power over long distances.

Poor Pointing and Tracking: Satellites and aeroplanes make transmitter-receiver alignment challenging. Signal degradation might result from aiming mistakes or transmitter tracking jitter sending many photons missing the receiver. This is a common constraint in optical communication networks.

Satellite-to-ground FSO refractive index fluctuates with pressure and temperature. Air turbulence can make the optical beam wander, spread, and scintillate, interfering with photon detection.

Scattering: Aerosols, fog, and rain can scatter light, deflecting photons or altering their angles.

Background Noise: The receiver may detect sunshine or terrestrial light in addition to signal photons. Background noise causes quantum key errors, raising QBER.

Comprehensive channel modelling is needed to estimate system performance with these impairments. These models consider receiver Field-of-View (FoV) filtering, transmitter tracking jitter, background photon influence, and link distance to provide design insights for system performance and key generation.

FSO QKD Progress and Future

Recent research has focused on system implementation and resolving long-distance FSO linkage issues for satellite QKD and broader space-based quantum communication networks. Analytical work emphasises how important precise channel modelling is for understanding and reducing these limitations.

Future research to improve FSO QKD systems will explore several exciting avenues:

Techniques: To mitigate aiming errors and air turbulence, powerful techniques are needed. Advanced signal processing and adaptive optics, which rectify mirror wavefront distortions, can improve connection performance and stability.

New modulation and coding schemes Novel ways of encoding information onto light and sophisticated error-correction codes can make quantum signals more impervious to FSO network noise and channel limitations.

Quantum Repeaters: Quantum repeaters are being studied to improve quantum communication range beyond signal loss. These devices may efficiently “boost” quantum signals while maintaining delicate quantum states, like classical repeaters.

New research is exploring hybrid architectures with unmanned aerial vehicles (UAVs) as relays or nodes in FSO networks. UAVs' increased flexibility and range suggest hybrid designs that combine the agility and cost of UAV-based communication with satellites' global coverage and stable platforms to boost FSO networks' reach and adaptability.

To provide secure communication in a tech-dependent environment, FSO-based satellite QKD is growing rapidly. Quantum physics, optical engineering, communication theory, and networking are needed to solve quantum communication system technical problems. FSO research and development are needed to fully realise this game-changing technology, which impacts government, finance, healthcare, and essential infrastructure.

The Potential of Quantum Processing Units(QPUs): The Quantum Revolution

Quantum Processing Units (QPUs) are the key concept of a brand new way of computing. The principle of a quantum computer is actually, first of all, a qubit or a quantum bit. QPUs are using qubits which are the smallest subatomic particles that can be used to represent and process huge amounts of information ¹. Unlike the classical computers, QPUs use the principles of quantum mechanics to solve complex tasks which are otherwise intractable for the fastest supercomputers.

How QPUs Work

QPUs exploit qubits through quantum logic gates following the laws of the basic principles of quantum physics and making slight adjustments ¹. Thereby, QPUs decode information in a period of time close to what would take a classical computer years to accomplish. The use of quantum algorithms gives QPUs an advantage to run code in a different manner which makes them uniquely suited for complex tasks such as large number factoring and molecular simulation.

Key Principles of Quantum Computing

Superposition: Qubits can exist in many states at the same time.

Entanglement: Qubits become linked and can then transfer information instantly.

Decoherence: Qubits are reduced to a state where the measurement can be done, which is a non-quantum state.

Interference: Qubits are in a state where they can enhance or cancel.

Advantages of QPUs

Parallel Processing: QPUs conduct multiple calculations in parallel.

Exponential Scaling: The number of qubits can grow exponentially with the number of qubits involved.

Probabilistic Computing: QPs detect probable outcomes among several alternatives thus reducing the overall computational time.

Real-World Applications

Cryptography: QPUs have enough power to crack some encryption protocols.

Optimization: QPUs show a remarkable result in resolving complicated optimization problems.

Simulation: QPUs make a correct reflection of complicated systems.

Leave aside the future, the QPUs have very high potential, but they are still in their infancy. As research continues, we may look forward to QPUs being a tool for various areas like medicine, finance, and materials science ². Computing, as we know it can be a promising adventure, and by means of QPUs, we can be part of this.
