The issue of tunneling time is replete with controversy and paradoxes. The controversy
stems from the fact that many tunneling time definitions seem to predict superluminal …

Using a two-photon interferometer, we have measured the time delay for a photon to tunnel
across a barrier consisting of a 1.1-μm-thick 1D photonic band-gap material. The peak of the …

A unified time analysis of photon and nonrelativistic particle tunnellings is presented, in
which time is regarded as a quantum observable, canonically conjugated to energy. Within …

In this revised and expanded edition, in addition to a comprehensible introduction to the
theoretical foundations of quantum tunneling based on different methods of formulating and …

Propagation of electromagnetic wave packets through 1D photonic band gap materials has
been studied using 12 fs optical pulses. The measured transit time is found to be …

The question in the title may be answered by considering the outcome of a “weak
measurement” in the sense of Aharonov, Albert, and Vaidman. Various properties of the …

Publisher Summary Measurements of tunneling times by photons possess certain
advantages over those by electrons or other particles, stemming from the fact that the …

It is argued that there is a sensible way to define conditional probabilities in quantum
mechanics, assuming only Bayes's theorem and standard quantum theory. These …

We demonstrate that although the well-known analogy between the time-independent
solutions for two-dimensional tunneling (eg, frustrated total internal reflection) and tunneling …

Recent experimental studies with microwave and laser pulses have revealed superluminal
(faster-than-light) group, signal and energy velocities for the tunneling of electromagnetic …
