Professor Masaaki Kondo and Visiting Researcher Yosuke Ueno (Special Postdoctoral Researcher, Graduate School of Information Science and Technology, The University of Tokyo) of the Faculty of Science and Technology, Keio University; Researcher Yasunari Suzuki of the Computer & Data Science Laboratories, Nippon Telegraph and Telephone Corporation; Assistant Professor Masamitsu Tanaka of the Graduate School of Engineering, Nagoya University, Tokai National Higher Education and Research System; and Unit Leader Yutaka Tabuchi of the RIKEN Center for Quantum Computing have developed the world's first quantum error correction algorithm to decode not only single logical qubits but also multiple interacting logical qubits. This algorithm operates in the cryogenic environment of superconducting quantum computers while meeting the required levels of power consumption, implementation scale, speed, and error correction performance necessary to control practical-scale quantum computers. The results of this research are expected to improve the scalability and error tolerance of qubits in superconducting quantum computers, contributing to the advancement of fault-tolerant quantum computer development.
These research results are scheduled to be presented at The 28th IEEE International Symposium on High-Performance Computer Architecture (HPCA-28), which will be held starting April 2, 2022.
