Interaction-Free Measurements
Lev Vaidman
A brief review of interaction-free measurements (IFM) is presented. The IFM is a solution of a quantum puzzle: How to test a bomb which explodes on every test without exploding it?…
Defending Time-Symmetrized Quantum Theory
Lev Vaidman
Recently, several authors have criticized time-symmetrized quantum theory originated by the work of Aharonov et al. (1964). The core of this criticism was the proof, which appeared…
On Schizophrenic Experiences of the Neutron or Why We Should Believe in the Many-Worlds Interpretation of Quantum Theory
Lev Vaidman
This is a philosophical paper in favor of the Many-Worlds Interpretation (MWI) of quantum theory. The concept of the ``measure of existence of a world'' is introduced and some diff…
Emergence of Weak Values
Lev Vaidman
Various quantum measurement procedures are analyzed and it is shown that under certain conditions they yield consistently {\em weak values} which might be very different from the e…
Reply to Comment: Quantum Cryptography Based on Orthogonal States?
Lior Goldenberg, Lev Vaidman
This is our Reply to Peres' Comment [quant-ph/9509003] to "Quantum Cryptography Based on Orthogonal States" [Phys. Rev. Lett. 75, 1239 (1995)].
Protective Measurements of Two-State Vectors
Y. Aharonov, L. Vaidman
A recent result about measurability of a quantum state of a single quantum system is generalized to the case of a single pre- and post-selected quantum system described by a two-st…
