无相互作用测量和前向散射

Interaction-free measurement and forward scattering

Tamás Geszti

摘要:

无相互作用的测量示出从伴随吸收的前向散射波产生:吸收体的“量子轮廓”。因此,该过程并非没有相互作用。对于理想的吸收体,前向散射波在振幅和相位上都被锁定。对于一个不完美的,它有一个非平凡的阶段的动力学起源(“彩色剪影”),可测量的干涉。其他例子的量子剪影,所有控制的幺正性,简要讨论。

英文摘要:

Interaction-free measurement is shown to arise from the forward-scattered wave accompanying absorption: a "quantum silhouette" of the absorber. Accordingly, the process is not free of interaction. For a perfect absorber the forward-scattered wave is locked both in amplitude and in phase. For an imperfect one it has a nontrivial phase of dynamical origin (``colored silhouette"), measurable by interferometry. Other examples of quantum silhouettes, all controlled by unitarity, are briefly discussed.
