光束的Stokes算符压缩和纠缠

Spatial state Stokes-operator squeezing and entanglement for optical beams

M. T. L. Hsu, W. P. Bowen, P. K. Lam

摘要:

光束的横向空间属性可以分解为位置、动量和轨道角动量观测量。光束的位置和动量与正交振幅直接相关,而轨道角动量与偏振和自旋变量相关。在本文中,我们研究了这些空间变量的量子特性,使用斯托克斯算子的基础上表示。我们提出了一个空间探测方案来测量所有三个空间变量,从而提出了一个方案的产生空间斯托克斯算符压缩和纠缠。

英文摘要:

The transverse spatial attributes of an optical beam can be decomposed into the position, momentum and orbital angular momentum observables. The position and momentum of a beam is directly related to the quadrature amplitudes, whilst the orbital angular momentum is related to the polarization and spin variables. In this paper, we study the quantum properties of these spatial variables, using a representation in the Stokes-operator basis. We propose a spatial detection scheme to measure all three spatial variables and consequently, propose a scheme for the generation of spatial Stokes operator squeezing and entanglement.
