Entangling distant stationary qubits—such as superconducting qubits, color centers, trapped ions, and phononic modes—commonly relies on flying photons transmitted through noisy channels. The fidelity of remote entanglement is severely degraded by channel noise. While entanglement purification can theoretically mitiga...

Long-distance entanglement distribution is hindered by photon loss in optical fibers and the nocloning theorem. Optical quantum repeater (QR) protocols rely on Bell state measurements (BSMs), they are intrinsically limited to probabilistic photon operations and fail 50% of the time. We propose a hybrid approach to buil...

Approximate quantum error correction (AQEC) extends the framework of discrete- and continuous-variable quantum error correction beyond the Knill-Laflamme (KL) conditions, where the recovery performance is quantified by entanglement fidelity. Recent studies have enabled efficient evaluation of near-optimal entanglement...
