Fujitsu and QuTech realize high-precision quantum gates

Fujitsu Limited Denmark Finland Germany Netherlands Sweden United Kingdom Japan New York Ontario

Fujitsu and QuTech achieve a world-first sub-0.1% error probability in a complete universal quantum gate set for diamond spin qubits, exceeding the threshold for quantum error correction, an important step towards fault tolerant quantum computing and the practical application of quantum computersHigh-purity diamonds with reduced carbon-13 isotope concentration and advanced performance measurement techniques were used to achieve over 99.9% fidelity in both single- and two-qubit gate operations, minimizing environmental noiseFuture collaborations will focus on scaling up the system by increasing the number of qubits and developing advanced optical interconnects and control circuitsView original content:https://www.prnewswire.co.uk/news-releases/fujitsu-and-qutech-realize-high-precision-quantum-gates-302409122.html
