Scalable diamond Quantum Computing with cryogenic chip integration

Researchers from QuTech, in a Fujitsu-funded project, have demonstrated the first cryogenic control chip capable of directly managing both electron and nuclear spins in diamond-based qubits. The innovation, which integrates a cryo-CMOS system-on-chip with nitrogen-vacancy (NV) centers in diamond, represents a significant step toward building scalable, high-fidelity quantum computers with diamond qubits. The results ...
