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…

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…
