Seeking a few Senior Scientists, Research Scientists or Postdoctoral Researchers (W24026)


Quantum Computer Architecture Research Team
RIKEN Center for Quantum Computing
(Team Leader: Hayato Goto)

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.
We theoretically study fault-tolerant quantum computation and its physical implementation and algorithm, which leads to total design of quantum computers, namely, quantum computer architecture. We also aim at cooperating systems of quantum and classical computers towards early realization of useful quantum computers.
