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 common the feature to be a definite outcome of some measurement. Elements of reality are extended to pre- and post- selected systems and to measurements which fulfill certain criteria of weakness of the coupling. Some features of the newly introduced concepts are discussed. 

Do weak values show the past of a quantum particle?

We investigate the use of weak values to determine the presence of an individual quantum particle. Specifically, we show issues with both Vaidman’s weak trace approach, and other approaches where a

The Two-State Vector Formalism of Quantum Mechanics

We present the two-state vector formalism of quantum mechanics. It is a time-symmetrized approach to standard quantum theory particularly helpful for the analysis of experiments performed on pre- and

The Two-State Vector Formalism: An Updated Review

The two-state vector formalism of quantum mechanics is a time-symmetrized approach to standard quantum theory particularly helpful for the analysis of experiments performed on preand post-selected

Information-reality complementarity in photonic weak measurements

The emergence of realistic properties is a key problem in understanding the quantum-to-classical transition. In this respect, measurements represent a way to interface quantum systems with the

Pedagogical Review of Quantum Measurement Theory with an Emphasis on Weak Measurements

The quantum theory of measurement has been with us since quantum mechanics was invented. It has recently been invigorated, partly due to the increasing interest in quantum information science. In

Time Symmetry and the Many-Worlds Interpretation

An attempt to solve the collapse problem in the framework of a time-symmetric quantum formalism is reviewed. Although the proposal does not look very attractive, its concept - a world defined by two

Quantum averages of weak values

We re-examine the status of the weak value of a quantum mechanical observable as an objective physical concept, addressing its physical interpretation and general domain of applicability. We show

What Is a Quantum-Mechanical “Weak Value” the Value of?

A so called “weak value” of an observable in quantum mechanics (QM) may be obtained in a weak measurement + post-selection procedure on the QM system under study. Applied to number operators, it has

Information-reality complementarity: The role of measurements and quantum reference frames

Recently, a measure has been put forward which allows for the quantification of the degree of reality of an observable for a given preparation [A. L. O. Bilobran and R. M. Angelo, Europhys. Lett.

Quantum mechanics and elements of reality

It is widely accepted that a Born probability of 1 is sufficient for the existence of a corresponding element of reality. Recently Vaidman has extended this idea to the ABL probabilities of the



Philosophy of quantum mechanics

In the recent literature the use of the term “Philosophy of Quantum Mechanics” is very similar to that of the corresponding term “Philosophy of Mathematics”. Its denotation includes a vast class of

Can Quantum-Mechanical Description of Physical Reality Be Considered Complete?

Consideration of the problem of making predictions concerning a system on the basis of measurements made on another system that had previously interacted with it leads to the result that one is led to conclude that the description of reality as given by a wave function is not complete.

Lorentz-invariant "elements of reality" and the joint measurability of commuting observables.

It is shown that joint measurements of certain commuting operators, performed on pre- and post-selected quantum systems, invariably disturb each other, resulting in a Lorentz-invariant interpretation of quantum theory.

On schizophrenic experiences of the neutron or why we should believe in the many‐worlds interpretation of quantum theory

Abstract This is a philosophical paper in favor of the many‐worlds interpretation (MWI) of quantum theory. The necessity of introducing many worlds is explained by analyzing a neutron interference

A description of quantum systems at the time interval between two successive measurements is presented, and how this approach leads to a new concept: a weak value of an observable.

"Relative State" Formulation of Quantum Mechanics

The task of quantizing general relativity raises serious questions about the meaning of the present formulation and interpretation of quantum mechanics when applied to so fundamental a structure as

Recently, we have proposed protective measurements1-* that allow the measuring of the Schrodinger wave of a single particle. We have argued that the possibility of such measurements tells us that a

THE paradox of Einstein, Podolsky and Rosen [1] was advanced as an argument that quantum mechanics could not be a complete theory but should be supplemented by additional variables. These additional
