Seeking a Research Part-time Worker I　(26-631)

Laboratory

Floating-Electron-Based Quantum Information RIKEN Hakubi Research Team
RIKEN Center for Quantum Computing
(RIKEN Hakubi Team Leader: Erika Kawakami)

Outline of Laboratory

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.

In our laboratory, we study floating electrons on the surface of liquid helium or solid neon. These physical systems hold high potential as an ideal platform for realizing quantum computers, as they are free of impurities and defects. We are also working on the technological development required for large-scale quantum computation.
