Routing Codes: High-Rate Quantum LDPC Codes with Short, Parallel Non-Local Connectivity
Researchers have introduced 'Routing Codes', a new family of quantum LDPC codes achieving a trade-off between high encoding rate and short, parallel non-local connectivity, bridging asymptotically good codes and practical near-term implementations.

The new routing codes could be demonstrated on near-term quantum processors, enabling higher-rate logical qubits with modest connectivity requirements.
The paper provides explicit small-size code families with short, parallel non-local connectivity, designed to reduce qubit overhead and simplify implementation on existing noisy devices, making experimental realization feasible within two years.
