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)].
Error Prevention Scheme with Four Particles
Lev Vaidman, Lior Goldenberg, Stephen Wiesner
It is shown that a simplified version of the error correction code recently suggested by Shor exhibits manifestation of the quantum Zeno effect. Thus, under certain conditions, pro…
Adiabatic Measurements on Metastable Systems
Y. Aharonov, S. Massar, S. Popescu +2
In several situations, most notably when describing metastable states, a system can evolve according to an effective non hermitian Hamiltonian. To each eigenvalue of a non hermitia…
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…
Weak-Measurement Elements of Reality
L. Vaidman
A brief review of the attempts to define ``elements of reality'' in the framework of quantum theory is presented. It is noted that most definitions of elements of reality have in c…
