- Abstract: We present a hybrid continuous variable-discrete variable entanglement generation protocol using linear optics and homodyne measurements, capable of producing multiple high-fidelity Bell pairs per protocol iteration, with an approximate $0.5$ success probability. The effectiveness of the protocol is determined by the squeezing strength. To increase the number of Bell pairs, approximately 3 dB of extra squeezing is needed for each additional Bell pair. The protocol also generates single Bell pairs with an approximate $0.75$ probability for squeezing strengths $\lessapprox 15dB$, achievable with current technology.

The ability of preparing perfect Bell pairs with a practical scheme is of great relevance for quantum communication and distributed quantum computing.
We propose a scheme which produces the perfect Bell pair from four copies of qubit pairs initially in the same arbitrary pure quantum state.
The scheme achieves success within just three iterations, making it attractive for real-world applications.
