RIKEN Center for Quantum Computing Superconducting Quantum Computing System Research Unit
Unit Leader: Yutaka Tabuchi (Ph.D.)
Research Summary
Our unit pursues the realization of practical quantum computers. We study a quantum mechanical system that integrates qubits, readout circuits, wiring, control electronics, cooling units, signal processing circuits, etc, to exploit and maximize a quantum mechanical feature in superconducting quantum chips. Each component has strengths and weaknesses, and the combination of those give trade-offs. We aim to establish a design method that harmonizes the elements to expand the performance and scalability of a quantum computing system.
