Quantum Reservoir Computing QRC For Soft Robot Control

Use quantum reservoir computing to explore quantum machine learning's frontiers. Keio University and Mitsubishi Chemical used QRC to study and forecast flexible soft robot behaviour.

Quantum Innovation Centres IBM

In 2017, Keio University became one of the first IBM Quantum Hubs, now QICs. There are about 40 QICs globally. QICs use IBM Quantum's expertise to advance quantum computing. These global hubs promote a worldwide quantum ecosystem, creative quantum research, and quantum learning communities by drawing participants to joint research initiatives.

Keio University works with leading Japanese companies to develop quantum applications and algorithms as a QIC. The university's partnership with Mitsubishi Chemical, a global materials science research and development leader, is an example. In 2023, scholars from the two organisations, the University of Tokyo, the University of Arizona, and the University of New South Wales conducted a utility-scale experiment utilising an IBM Quantum device to execute a proposed quantum reservoir computing technology. This investigation established a thriving research endeavour.

Reservoir computing with utility-scale quantum computation

Reservoir computing (RC) reduces the training overhead of neural networks and generative adversarial networks. A reservoir is a computing resource that can conduct mathematical transformations on incoming system data, allowing large datasets to be manipulated while keeping data point connections.

Researchers send input system data to the reservoir in a reservoir computing experiment. Researchers will use post-processing to find answers in the reservoir's changed data. This post-processing often uses the linear regression model, an ML model for variable relationships. After training a linear regression model using reservoir output data, researchers can construct a time series that predicts input system behaviour.

Quantum reservoir computing (QRC) uses quantum computers as its reservoir. Quantum computers, which may surpass standard systems in computing capability, are ideal for high-dimensional data processing.

Mitsubishi Chemical, Keio University, and others are studying how quantum reservoir computing might help comprehend complicated natural systems. Their 2023 experiment aimed to create a quantum reservoir computing model that could predict the noisy, non-linear motions of a "soft robot," a malleable device controlled by air pressure.

Creating Quantum Reservoir Computing techniques

The researchers converted robot movement data into IBM quantum reservoir-readable quantum input states to begin the experiment. These inputs reached the reservoir. After applying random gates to input states, the reservoir produces changed signals. After that, researchers post-process output data with linear regression. The result is a robot movement prediction time series. The researchers evaluate this prediction against real data to determine its accuracy.

Most quantum reservoir computing systems measure at the end of a quantum circuit, therefore you must build up and run the system for every qubit at every time step. This can increase experiment duration and reduce time series accuracy. The Keio University and Mitsubishi Chemical research sought to overcome these limitations with “repeated measurements”.

They add qubits and measure them repeatedly instead of setting up and executing the system at each time step. This method allows researchers to collect the time series at once, resulting in a more accurate series and less circuit time.

The researchers demonstrated their quantum reservoir computing system using IBM Quantum processors with up to 120 qubits. They found that repeated measurements yielded higher accuracy and faster execution than standard QRC methods. Their first studies suggest it might accelerate calculating.

Before RC and quantum reservoir computing can solve problems, additional research is needed. The researchers say their utility-scale investigations may outperform standard modelling methods. They plan to study quantum reservoir computing for nonlinear problems like financial risk modelling.

How Quantum Innovation Centres Help Enterprise Research Organisations

Keio University and Mitsubishi Chemical's relationship is an example of how businesses may benefit from IBM Quantum Innovation Centre partnerships. Professors and students who are strong in quantum computing and at teaching other researchers in difficult issues may assist enterprise researchers achieve advanced quantum skills through these relationships.

Not just Mitsubishi Chemical, but also other global firms are benefiting from this. In addition to Mistubishi Chemical, Keio University is collaborating with corporate R&D teams from leading companies in many industries and quantum use cases to investigate exciting quantum applications and algorithm development. These collaborations show how industry research trials with universities may lead to valuable real-world applications and how QICs can help corporations explore fascinating quantum use cases.
