Demonstrating nonlocality-induced teleportation through Majorana bound states in a semiconductor nanowire

• We analyze a concrete measurement scheme for Majorana teleportation.
• This phenomenon is unusual since it seemingly contradicts the principle of relativity.
• The analysis is based on a conditional quantum-jump technique.
• The proposed scheme is accessible by nowadays state-of-the-art experiments.

It was predicted by Tewari et al. (2008) [15] that a teleportation-like electron transfer phenomenon is one of the novel consequences of the existence of Majorana fermion, because of the inherently nonlocal nature. In this work we consider a concrete realization and measurement scheme for this interesting behavior, based on a setup consisting of a pair of quantum dots which are tunnel-coupled to a semiconductor nanowire and are jointly measured by two point-contact detectors. We analyze the teleportation dynamics in the presence of measurement back-action and discuss how the teleportation events can be identified from the current trajectories of strong response detectors.
