Utilizes bosonic quantum error correction codes as long-coherence-time storage qubits, repetitively generating entanglement and injecting it into error-detectable logical qubits to significantly extend entanglement lifetime, offering a new paradigm for efficient entanglement management in scalable quantum networks.
