AB and Berry phases for a quantum cloud of charge
Y. Aharonov, S. Coleman, A. S. Goldhaber +5
We investigate the phase accumulated by a charged particle in an extended quantum state as it encircles one or more magnetic fluxons, each carrying half a flux unit. A simple, esse…
Elements of Reality and the Failure of the Product Rule Measurability of Commuting Observables
Lev Vaidman
The concept of ``elements of reality" is analyzed within the framework of quantum theory. It is shown that elements of reality fail to fulfill the product rule. This is the core of…
Measurement of Nonlocal Variables without Breaking Causality
Lev Vaidman
We report results of an investigation of relativistic causality constraints on the measurability of nonlocal variables. We show that measurability of certain nondegenerate variable…
Lorentz-Invariant "Elements of Reality" and the Question of Joint Measurability of Commuting Observables
Lev Vaidman
It is shown that the joint measurements of some physical variables corresponding to commuting operators performed on pre- and post-selected quantum systems invariably disturb each…
Measurements, errors, and negative kinetic energy
Y. Aharonov, S. Popescu, D. Rohrlich +1
An analysis of errors in measurement yields new insight into the penetration of quantum particles into classically forbidden regions. In addition to ``physical" values, realistic m…
Teleportation of Quantum States
Lev Vaidman
Bennett et al. (PRL 70, 1859 (1993)) have shown how to transfer ("teleport") an unknown spin quantum state by using prearranged correlated quantum systems and transmission of class…
Quantum Mechanical Interaction-Free Measurements
Avshalom C. Elitzur, Lev Vaidman
A novel manifestation of nonlocality of quantum mechanics is presented. It is shown that it is possible to ascertain the existence of an object in a given region of space without i…
The Schrodinger Wave is Observable after All!
Yakir Aharonov, Lev Vaidman
It is shown that it is possible to measure the Schrödinger wave of a single quantum system. This provides a strong argument for associating physical reality with a quantum state of…
Measurement of the Schrodinger wave of a single particle
Yakir Aharonov, Lev Vaidman
We show that it is possible to measure Schrodinger wave of a single quantum system. This provides a strong argument for associating physical reality with the quantum state of a sin…
