University of Tokyo

The University of Tokyo is a national research university whose physics and applied-physics departments host several of Japan's leading quantum computing groups rather than a single corporate program. Yasunobu Nakamura's laboratory works on superconducting qubits, building on his 1999 demonstration of coherent control in a Cooper-pair box; Akira Furusawa's group develops continuous-variable optical quantum computing with squeezed light; and semiconductor spin-qubit research is pursued in applied physics. It is an academic institution, not a company, and is not publicly traded.

Researchers Demonstrate Building Blocks for Zinc Oxide Spin Qubits

Researchers at Tohoku University, in collaboration with NIMS and the University of Tokyo, demonstrated charge sensing, high-frequency reflectometry, and a few-electron double quantum dot in zinc oxide. The work establishes basic building blocks for semiconductor spin qubits based on ZnO.

OutlookPlausible

The demonstrated charge-sensing and few-electron double quantum dot could enable the first spin-state readout and single-qubit control experiments in zinc oxide within two years.
