Optqc Team Builds Constant-Rate Quantum Codes with Full Clifford Actions
Researchers at OptQC have constructed quantum error-correcting codes that achieve a constant encoding rate while supporting the full Clifford group of logical operations. The codes use only transversal and fold-transversal gates, avoiding the need for additional qubits or restricted logic. The construction is based on classical codes with automorphism group symmetries.
This could allow near-term fault-tolerant processors to execute the full Clifford group on logical qubits with much lower overhead, making practical error-corrected demonstrations feasible within two years.
