In this paper 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 experimentsâ€¦ (More)

This work is inspired by our discussions with David Bohm in different periods in Tel-Aviv, London, and South Carolina. We were excited by the results we obtained in the framework of two-state vectorâ€¦ (More)

It is proposed that superoscillations play an important role in the interferences that give rise to superluminal effects. To exemplify that, we consider a toy model that a wave packet to travel inâ€¦ (More)

We consider circumstances wherein a quantum-mechanical system is subjected to a varied sequence of measurements, someof which are substantially more precise than others. Such systems are shown toâ€¦ (More)

Suppose that the Hamiltonian acting on a quantum system is unknown and one wants to determine which is the Hamiltonian. We show that, in general, this requires a time Dt that obeys the uncertaintyâ€¦ (More)

We consider the tunnelling particle as a preand post-selected system and prove that the tunnelling time is the expectation value of the position of a â€˜clockâ€™ degree of freedom weakly coupled to it.â€¦ (More)
