Silicon quantum chip demonstrates full, error-detecting logical operations
TL;DR Summary
Shenzhen researchers built a silicon-based quantum processor with four physical qubits encoding two logical qubits that can detect errors during computation, completing a full chain of operations and running a water-molecule ground-state algorithm via the Variational Quantum Eigensolver; this marks a milestone toward fault-tolerant, scalable silicon quantum computing, with next steps to increase qubits and reduce interference, as reported in Nature Nanotechnology.
