Proposal for a new quantum computer architecture that separates the memory and processor

–Paving the way to practical quantum computation with a highly memory-efficient design with excellent portability

(2025/03/04)

Takumi Kobori, a graduate student (an intern at Nippon Telegraph and Telephone Corporation at the time) and Professor Synge Todo of the Graduate School of Science at The University of Tokyo, Researchers Yasunari Suzuki and Yuuki Tokunaga of Nippon Telegraph and Telephone Corporation, Research Fellow Yosuke Ueno of the RIKEN Quantum Computer Science Institute, and Associate Professor Teruo Tanimoto of the Graduate School of Systems Information Science, Kyushu University, have proposed a new architecture for error-tolerant quantum computation that applies the basic design of conventional computers to quantum computers.  This technology is expected to accelerate the early realization of useful quantum computation by enabling high portability of programs (ease of migration to other environments) and utilization of highly efficient quantum hardware.
