论文摘要
在自发参数下转换中产生的光子对自然纠缠在其横向空间自由度，包括轨道角动量。以零阶高斯模式泵送非线性晶体会产生相关的信号和相同的轨道角动量和相反符号的惰性信号。在一个光子之一上执行的测量值远程准备了另一个光子的状态。我们从该系统中的远程状态制备从其在量子热力学上的潜在应用的角度研究。
Photon pairs produced in spontaneous parametric down-conversion are naturally entangled in their transverse spatial degrees of freedom including the orbital angular momentum. Pumping a non-linear crystal with a zero order Gaussian mode produces quantum correlated signal and idler photons with equal orbital angular momentum and opposite signs. Measurements performed on one of the photons prepares the state of the other remotely. We study the remote state preparation in this system from the perspective of its potential application to Quantum Thermodynamics.
