Loss-tolerant concatenated Bell-state measurement with encoded coherent-state qubits for long-range quantum communication
The coherent-state qubit is a promising candidate for optical quantum information processing due to its nearly deterministic nature of the Bell-state measurement (BSM). However, its nonorthogonality incurs difficulties such as the failure of the BSM. One may use a large amplitude (α) for the coheren...
