Entanglement‐buildup through charged‐exciton decay in a semiconductor quantum dot
Ulrich Hohenester, Claudia Sifel
Abstract
We analyze the decay of a single-electron charged exciton in a quantum dot embedded in a field effect structure. We show how the quantum properties of the charged exciton are transferred through tunneling and relaxation to the spin entanglement between electrons in the dot and contact, carefully examine the proper theoretical description of the underlying scattering processes, and identify the pertinent disentanglement mechanisms.
