Transduction-enabled superconducting quantum repeater: Toward deterministic entanglement distribution with high-fidelity gates

Aps.org·October 5, 2026

Long-distance entanglement distribution is hindered by photon loss in optical fibers and the no-cloning theorem. Optical quantum repeater (QR) protocols rely on Bell-state measurements (BSMs); they are intrinsically limited to probabilistic photon operations …
