摘要
利用Bell-CHSH(Clauser-Home-Shimony-Holt)不等式研究了两种纠缠的光学薛定谔猫态的量子非定域性及其在真空热库中的演化.计算表明,最大纠缠的薛定谔猫态具有最大的量子非定域性.在真空热库中随着时间的演化,两种纠缠态的量子非定域性逐渐减弱直至消失.
Abstract
The quantum nonlocality of two kinds of entangled optical Schrodinger-cat states and its evolution in a vacuum thermal revervoir are studied by using the Bell-CHSH (Clauser-Horne-Shimony-Holt) inequalities. The derived result shows that the maximally entangled Schrodinger-cat state has the maximal quantum nonlocality. Under the time evolution in a vacuum thermal reservoir, quantum nonlocality of the two kinds of entangled states decreases gradually and disappears finally.
