# Dual-rail superconducting qubits reach 98.1% CNOT fidelity at 13% erasure - Date: 2026-03-26 - Category: Quantum Computing A team at the Shenzhen International Quantum Academy has demonstrated multi-qubit entanglement using a superconducting processor built from dual-rail erasure qubits — an architecture that treats the dominant error type in superconducting systems as detectable rather than invisible. ---
