Superconducting circuits boost long-distance quantum entanglement by 63%

A new transduction-enabled quantum repeater, utilizing superconducting circuits, achieves a 63% increase in long-distance entanglement.
The proposed transduction-enabled superconducting quantum repeater (TESQR) architecture eliminates the need for probabilistic Bell state measurements and allows deterministic processing operations. The TESQR framework always yields a final state at the remote nodes rather than aborting on photon loss. After purification, the end-to-end fidelities exceed 0.8 over distances up to 20 kilometers. This new approach directly performs entanglement swapping operations within superconducting circuits, a shift that allows for deterministic processing rather than relying on chance outcomes. The TESQR framework integrates optical-microwave transduction with superconducting qubits, capitalizing on the strengths of both technologies to overcome individual weaknesses in long-distance quantum communication. This hybrid design uses the high transmission speeds of photonic qubits in optical fiber alongside the high-fidelity quantum processing capabilities of superconducting circuits, a…
