Hongbin Song, Heyu Huang, Hao Liu, Ai Zhou, Guofeng Zhang, Hidehiro Yonezawa · 2024
We present and analyze the quantum entanglement generated from two-photon joint subtraction from two-mode squeezed vacuum states (TMSV). Larger entanglement negativity than single-photon jointly subtracted TMSV, photon-subtracted TMSV and TMSV is obtained when the squeezing parameter, ξ ≤ 0.58.
