Universal Logical Operations Implemented in Silicon Donor Quantum Processor

Researchers from the Shenzhen International Quantum Academy have demonstrated a silicon-based quantum processor capable of executing a universal set of logical gate operations. The device utilizes a cluster of five phosphorus donor nuclear spins embedded in an isotopically purified silicon-28 lattice, patterned with atomic precision via scanning tunneling microscopy (STM) lithography. To manage environmental noise, […]
