论文摘要
我们考虑了基于单电子源和检测器的双轨电子量子量子态的按需传送方案。该方案的最大效率为25％，这受到共享纠缠状态和钟形测量的限制。我们考虑了两个实验实现，可以通过当前技术实现。第一个依赖于表面声波，其中所有成分易于使用。第二个基于量子厅边缘通道中的洛伦兹电压脉冲。由于在这些系统中尚未实验建立单电子检测，因此我们考虑使用电流相关器对传送的层析成像检测，直到（包括）三阶。对于这两种实施，我们都考虑了环境影响。
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.
