Quantum state estimation for continuously monitored dynamical systems involves assigning
a quantum state to an individual system at some time, conditioned on the results of …

While quantum reality can be probed through measurements, the Two-State Vector
Formalism (TSVF) reveals a subtler reality prevailing between measurements. Under special …

Intuition from our everyday lives gives rise to the belief that information exchanged between
remote parties is carried by physical particles. Surprisingly, in a recent theoretical study …

Here we report a type of dynamic effect that is at the core of the so called “counterfactual
computation” and especially “counterfactual communication” quantum effects that have …

In quantum mechanics, the concept of weak measurements allows for the description of a
quantum system both in terms of the initial preparation and the final state (post-selection) …

One of the most intriguing aspects of quantum mechanics is the impossibility of measuring at
the same time observables corresponding to noncommuting operators, because of quantum …

Recent controversy regarding the meaning and usefulness of weak values is reviewed. It is
argued that in spite of recent statistical arguments by Ferrie and Combes, experiments with …

We report an experimental realization of a modified counterfactual communication protocol
that eliminates the dominant environmental trace left by photons passing through the …

The modification of the effect of interactions of a particle as a function of its preselected and
postselected states is analyzed theoretically and experimentally. The universality property of …

A novel prediction is derived by the Two-State-Vector-Formalism (TSVF) for a particle
superposed over three boxes. Under appropriate pre-and post-selections, and with …
