Protective Measurements
Yakir Aharonov, Lev Vaidman
Protective measurements yield properties of the quantum state of a single quantum system without affecting the quantum state. A protective measurement involves adiabatic coupling t…
Weak Measurements
Lev Vaidman
Weak measurement is a standard measuring procedure with two changes: it is performed on pre- and post-selected quantum systems and the coupling to the measuring device is weakened.…
The Meaning of Protective Measurements
Yakir Aharonov, Jeeva Anandan, Lev Vaidman
Protective measurements, which we have introduced recently, allow to measure properties of the state of a single quantum system and even the Schrödinger wave itself. These measurem…
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…
