High-Efficiency Quantum Error Correction Promises Smaller, Stronger Quantum Computers

Researchers present bivariate bicycle (BB) LDPC quantum codes that preserve logical qubits with 10× fewer physical qubits than surface codes. Using 288 physical qubits, 12 logical qubits can survive ~1 million error-correction cycles. The approach is compatible with superconducting architectures and...
