单电子态的量子隐形传态

Quantum teleportation of single-electron states

Edvin Olofsson, Peter Samuelsson, Nicolas Brunner, Patrick P. Potts

摘要:

我们考虑了一个基于单电子源和探测器的双轨电子量子比特态的按需传送方案。该方案的最大效率为25%,这受到共享纠缠态和Bell态测量的限制。我们考虑两个实验实现,实现与当前的技术。第一种依赖于表面声波,其中所有成分都是现成的。第二种是基于量子霍尔边缘通道中的洛伦兹电压脉冲。由于单电子检测尚未实验建立在这些系统中,我们认为使用电流放大器的隐形传态的断层检测(包括)三阶。对于这两种实现方式,我们都考虑了环境影响。

英文摘要:

We consider a scheme for on-demand teleportation of a dual-rail electron qubit state, based on single-electron sources and detectors. The scheme has a maximal efficiency of 25%, which is limited both by the shared entangled state as well as the Bell-state measurement. We consider two experimental implementations, realizable with current technology. The first relies on surface acoustic waves, where all the ingredients are readily available. The second is based on Lorentzian voltage pulses in quantum Hall edge channels. As single-electron detection is not yet experimentally established in these systems, we consider a tomographic detection of teleportation using current correlators up to (and including) third order. For both implementations we take into account environmental effects.
