我们证明，量子粒子，最初准备在量子阱中，可以通过一个连续的光谱传播的水库，并重新出现在一个遥远的井没有被登记在水库。它示出，这样的通道通过水库发生，即使后者是连续监测。我们讨论了在介观系统中实现这种隐形传态现象的可能实验。(c)2013爱思唯尔有限公司版权所有。
We demonstrate that a quantum particle, initially prepared in a quantum well, can propagate through a reservoir with a continuous spectrum and reappear in a distant well without being registered in the reservoir. It is shown that such a passage through the reservoir takes place even if the latter is continuously monitored. We discuss a possible experimental realization of such a teleportation phenomenon in mesoscopic systems. (c) 2013 Elsevier B.V. All rights reserved.
