Scientists develop novel high-fidelity quantum computing gate

Summary

Nutrition label

92% Informative

Researchers from the RIKEN Center for Quantum Computing and Toshiba have succeeded in building a quantum computer gate based on a double-transmon coupler.

The DTC is a new kind of tunable coupler composed of two fixed-frequency transmons, a type of qubit that is relatively insensitive to noise arising from charge.

Using this, they achieved a fidelity of 99.92% for a two -qubit device known as a CZ gate.
