A new study from researchers at Japan’s RIKEN Center for Quantum Computing and Toshiba reveals a high-fidelity quantum gate that promises to significantly improve the performance of existing noisy intermediate-scale quantum (NISQ) devices.
Like logic gates in classical computers, quantum computing applications require quantum gates to change the state of qubits —- enabling them to perform complex calculations.
A new study from researchers at Japan’s RIKEN Center for Quantum Computing and Toshiba reveals a high-fidelity quantum gate that promises to significantly improve the performance of existing noisy intermediate-scale quantum devices.The newly developed gate utilizes a double-transmon coupler , a component that allows precise control over how two qubits interact.
“An average gate fidelity surpassing 99.9%, for example, would enable not only efficient fault-tolerant quantum computing with error correction but also effective mitigation of errors in current noisy intermediate-scale quantum devices,” the study authors added.
