我们提出了一种通过介观导体中电势随时间变化动态创建轨道纠缠电子空穴对的方案。与时间相关的电势在导体的两个不同轨道区域中产生电子空穴对的叠加，这是量子霍尔体系中的双粒子干涉仪。轨道纠缠是通过违反贝尔不等式来检测的，贝尔不等式是用零频率电流噪声表示的。考虑了弱振幅限制和强振幅限制下的势能绝热循环。
We propose a scheme for dynamically creating orbitally entangled electron-hole pairs through a time-dependent variation of the electrical potential in a mesoscopic conductor. The time-dependent potential generates a superposition of electron-hole pairs in two different orbital regions of the conductor, a two-particle interferometer in the quantum Hall regime. The orbital entanglement is detected via violation of a Bell inequality, formulated in terms of zero-frequency current noise. Adiabatic cycling of the potential, in both the weak and strong amplitude limits, is considered.
