Optimal electron entangler and single electron source at low temperatures
arXiv:0812.4433 · doi:10.1103/PhysRevB.80.041313
Abstract
Electron transport in mesoscopic contacts at low temperatures is accompanied by logarithmically divergent equilibrium noise. We show that this equilibrium noise can be dramatically suppressed in the case of a tunnel junction with modulated (time-dependent) transparency, and identify the optimal protocol. We show how such a contact could be used either as an optimal electron entangler or as a single-electron source with suppressed equilibrium noise at low temperatures.
