Full control of a six-qubit quantum processor in silicon

https://phys.org/news/2022-09-full-six-qubit-quantum-processor-silicon.html

"quantum arrays 50 superconducting qubits... individual electrons linear array six quantum dots 90 nanometers apart... silicon chip... finely-tuned microwave radiation, magnetic fields, and electric potentials control and measure spin individual electrons... interact with each other... high initialization readout fidelities, high single-qubit gate fidelities, and high two-qubit state fidelities... increase the silicon spin qubit count while keeping the same precision as for single qubits... low error rates"
