Silicon Quantum Processor Achieves Universal Logical Gate Set

Researchers at the Shenzhen International Quantum Academy demonstrated a silicon-based quantum processor executing a universal set of logical gate operations, including T-gates and CNOT operations, using five phosphorus donor nuclear spins in an isotopically purified silicon-28 lattice. Published in Nature Nanotechnology, the result validates error-corrected quantum computing on a platform fully compatible with existing CMOS semiconductor manufacturing.
