The basic concept of the two-state vector formalism, which is the time symmetric approach to quantum mechanics, is the backward evolving quantum state. However, due to the time asymmetry of the memory's arrow of time, the possible ways to manipulate a backward evolving quantum state differ from those for a standard, forward evolving quantum state. The similarities and the differences between forward and backward evolving quantum states regarding the no-cloning theorem, nonlocal measurements and… Expand

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 twoExpand

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-selectedExpand
Quantum Instruments as a Foundation for Both States and Observables
We demonstrate that quantum instruments can provide a unified operational foundation for quantum theory. Since these instruments directly correspond to laboratory devices, this foundation provides anExpand
Retrocausality and Quantum Measurement
A retrocausal interpretation of quantum mechanics is examined and is applied to the problem of measuring an optical qubit before the qubit is actually created. Although the predictions of theExpand

This paper relates both to the metaphysics of probability and to the physics of time asymmetry. Using the formalism of decoherent histories, it investigates whether intuitions about intrinsic timeExpand
Weak value beyond conditional expectation value of the pointer readings
It is argued that a weak value of an observable is a robust property of a single pre- and postselected quantum system rather than a statistical property. During an infinitesimal time a system with aExpand

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. Expand

We suggest an interpretation of quantum mechanics, inspired by the ideas of Aharonov et al. of a time-symmetric description of quantum theory. We show that a special final boundary condition for theExpand

TLDR
The recent result of Bennett of teleportation of an unknown quantum state is obtained in the framework of nonlocal measurements proposed by Aharonov and Albert, and the latter method is generalized to the teleportation of a quantum state of a system with continuous variables. Expand

TLDR
It is proved that verification measurements of entangled states necessarily erase local information and it is shown that measurability of certain projection operators which play an important role in axiomatic quantum theory contradicts the causality principle. Expand
