自由粒子的量子纠缠

Quantum Entanglement of Free Particles

Roumen Tsekov

摘要:

对多个自由粒子求解薛定谔方程,通过关联分析研究了它们之间的量子纠缠。将薛定谔方程转化为类马德隆流体力学形式,通过加入欧姆摩擦力,将量子力学推广到开放量子系统。耗散演化证实了关联随时间的衰减,但发现了一个新的运动积分,适合于存储永久的量子信息。

英文摘要:

The Schrodinger equation is solved for many free particles and their quantum entanglement is studied via correlation analysis. Converting the Schrodinger equation in the Madelung hydrodynamic-like form, the quantum mechanics is extended to open quantum systems by adding Ohmic friction forces. The dissipative evolution confirms the correlation decay over time, but a new integral of motion is discovered, being appropriate for storing everlasting quantum information.
