Seeking a few Technical Staffs I or II (W23167)


Theoretical Quantum Physics Laboratory,
RIKEN Cluster for Pioneering Research
(Laboratory head: Franco Nori, Chief Scientist)

Research Field

Our top priorities are now: (1) quantum computing using superconducting qubits, (2) coherent Ising machines, and (3) neural networks and machine learning applied to quantum physics. Candidates with prior experience in these topics will have priority.

We perform interdisciplinary research in theoretical quantum information processing, atomic physics, quantum optics, condensed matter physics, nanoscience, and computational physics. We are also studying hybrid quantum electro-mechanical systems, optomechanics, nano-mechanics, quantum nano-electronics, and quantum simulations. Particular emphasis is being placed on quantum computing using superconducting Josephson-junction qubits, scalable quantum circuitry and improved designs for their quantum control. An underlying theme of our work is to better understand nano-scale quantum systems and devise methods to control them. We use physical models to make predictions that can be tested experimentally and that can be used to better understand the observed phenomena.
Our publications are available online at Publications | Theoretical Quantum Physics Laboratory website.
