Energy-time entanglement of quasi-particles in solid-state devices

摘要

We present a proposal for the experimental observation of energy-timeentanglement of quasi-particles in mesoscopic physics. This type ofentanglement arises whenever correlated particles are produced at the same timeand this time is uncertain in the sense of quantum uncertainty, as has beenlargely used in photonics. We discuss its feasibility for electron-hole pairs.In particular, we argue that the recently fabricated 2DEG-2DHG junctions,irradiated with a continuous laser, behave as "entanglers" for energy-timeentanglement.
