Silicon Quantum Processor Logical Operations Mark Key Step in China Research

A research team in Shenzhen has built a small silicon quantum processor that performs a complete set of logical operations while detecting errors. Scientists encoded four physical qubits into two logical qubits and successfully ran single-qubit and two-qubit gates. They even executed a basic algorithm to estimate the ground-state energy of a water molecule. This progress shows silicon could support reliable, large-scale quantum machines compatible with existing chip manufacturing.
