Seeking a few Postdoctoral Researchers (W22103)


Superconducting Quantum Simulation Research Team
RIKEN Center for Quantum Computing
(Team Leader: Jaw-Shen Tsai)

Research Field

The missions of RIKEN Center for Quantum Computing (RQC) are to deepen our understandings of quantum mechanics and quantum information, develop techniques for quantum control and measurement, build quantum computing hardware and software, and explore novel applications. We promote basic research on quantum information science and contribute to society through quantum technology.
Superconducting qubit possesses high degree of freedoms in the circuit design and ability to local control as well as readout quantum states. Utilizing these properties, the development of small scale quantum analog simulator that aiming for the simulations of macroscopic material properties is targeted. Study of non-equilibrium quantum dynamics in these circuits is also planned.
