Oxford Ionics, a quantum computing startup, recently announced that it has successfully developed the world's highest-performing quantum chip, with a fidelity of 99.97% for its two-qubit gates and a fidelity of 99.9992% for single-qubit operations, both setting new industry records. The company said that by developing a patented Electronic Qubit Control system, it has eliminated the scalability obstacle of traditional ion trap quantum computers that require lasers to control qubits.

Quantum computing developer Diraq announced yesterday that IMEC has successfully manufactured their silicon spin qubits on 300mm silicon wafers using standard CMOS materials and processes, achieving 99.9% fidelity in single qubit control. This milestone enables Diraq to achieve the precision necessary for producing robust error-corrected quantum computers in existing silicon foundries. It is reported that Diraq-designed quantum chips will be manufactured this year by GlobalFoundries using their 22FDX technology.
