摘要:
在量子光学中,光子扣除是一种最为基本的非高斯操作。当光子扣除操作执行于光场的一般高斯型量子态-双模压缩相干态时,可以得到一种非高斯型量子态,即光子扣除双模压缩相干态。研究结果表明:对量子态的2个模扣除相同的光子数可以明显地增强双模压缩相干态的双模压缩以及和压缩效应,而对量子态的2个模扣除不同的光子数通常会削弱态的压缩性质。
Abstract:
Photon subtraction is a basic non-Gaussian operation in quantum optics. Applying photon subtraction on a general Gaussian state(two-mode squeezed coherent state)of light field, one can obtain a non-Gaussian state, called photon-subtracted two-mode squeezed coherent state. Our results indicate that the symmetry photon subtraction can clearly enhance the two-mode squeezing and sum squeezing of the state. While the asymmetry photon subtraction generally weak the squeezing effect.
