NEURAL NETWORKS CONTROLLING SUPERCONDUCTING QUANTUM CIRCUITS

This website provides information about the project entitled "Neural networks controlling superconducting quantum circuits" that was funded in the 2021 QuantERA program of the European Union. The ARTEMIS project aims at establishing and commercializing a radically new neural-networks-based quantum control approach. It will use reinforcement learning on real time experimental observations in order to overcome today's main challenges in quantum computing - quantum error correction and optimal control.

Kick-off meeting, ENS de Lyon, July 2022.

PARTNERS

Principal Investigators

Benjamin Huard (coordinator)

Benjamin Huard is a professor at Ecole Normale Supérieure de Lyon in France where he leads the Quantum Circuit Group together with Audrey Bienfait. He coordinates the Artemis project and will lead the corresponding experimental effort at ENS de Lyon.






Florian Marquardt

Florian Marquardt is currently scientific director of the Max Planck Society, at the Max Planck Institute for the Science of Light (MPL) in Erlangen, Germany. There, he leads the theory division. Florian Marquardt and his team will be mainly responsible for developing the theory required for successful completion of the project, including the development of new reinforcement learning training approaches, neural network structures, etc. In that way, they will contribute to all theory-related parts of the project.






Yonatan Cohen

Yonatan Cohen is the CTO and a co-founder at QM. Dr. Cohen has a PhD in physics from the Weizmann Institute, working on carbon nanotube quantum systems at the lab of Prof. Moty Heiblum, and holds an M.Sc. and B.Sc. in physics from the Weizmann Institute and the University of Washington, respectively. He will be mostly in charge of developing the control hardware on which to embed the neural networks.






Raphaël Lescanne

Raphaƫl Lescanne is the CTO and co-founder of Alice and Bob. He has a PhD in experimental quantum physics from ENS Paris, working on quantum error correction with superconducting cat-qubits. He will be mostly in charge elaborating to the cloud platform to give access to the RL-NN operated quantum hardware.
