Charge acceleration without radiation
Yakir Aharonov, Daniel Collins, Sandu Popescu
The existence of electromagnetic radiation - radio-waves, microwaves, light, x-rays and so on - is one of the most important physical phenomena, and our ability to manipulate them…
Conservation Laws For Every Quantum Measurement Outcome
Daniel Collins, Sandu Popescu
In the paradigmatic example of quantum measurements, whenever one measures a system which starts in a superposition of two states of a conserved quantity, it jumps to one of the tw…
Conservation laws and the foundations of quantum mechanics
Yakir Aharonov, Sandu Popescu, Daniel Rohrlich
In a recent paper, PNAS, 118, e1921529118 (2021), it was argued that while the standard definition of conservation laws in quantum mechanics, which is of a statistical character, i…
Angular Momentum Flows without anything carrying it
Yakir Aharonov, Daniel Collins, Sandu Popescu
Transfer of conserved quantities between two remote regions is generally assumed to be a rather trivial process: a flux of particles carrying the conserved quantities propagates fr…
Open Quantum System Approach to the Modeling of Spin Recombination Reactions
M. Tiersch, U. E. Steiner, S. Popescu +1
In theories of spin-dependent radical pair reactions, the time evolution of the radical pair, including the effect of the chemical kinetics, is described by a master equation in th…
Semifluxon degeneracy choreography in Aharonov-Bohm billiards
M V Berry, S Popescu
Every energy level of a charged quantum particle confined in a region threaded by a magnetic flux line with quantum flux one-half must be degenerate for some position of the semifl…
A Novel Phase Shift Acquired due to Virtual Forces
T. Kaufherr, Y. Aharonov, S. Nussinov +2
This paper has been withdrawn by the author.
Multiple-time states and multiple-time measurements in quantum mechanics
Y. Aharonov, S. Popescu, J. Tollaksen +1
We discuss experimental situations that consist of multiple preparation and measurement stages. This leads us to a new approach to quantum mechanics. In particular, we introduce th…
Experimental Realization of Teleporting an Unknown Pure Quantum State via Dual Classical and Einstein-Podolski-Rosen Channels
D. Boschi, S. Branca, F. De Martini +2
We report on a quantum optical experimental implementation of teleportation of unknown pure quantum states. This realizes all the nonlocal aspects of the original scheme proposed b…
Quantum Measurement Back-Reaction and Induced Toplogical Phases
Y. Aharonov, T. Kaufherr, S. Popescu +1
It is shown that a topological vector-potential (Berry phase) is induced by the act of measuring angular momentum in a direction defined by a reference particle. This vector potent…
Jamming non-local quantum correlations
J. Grunhaus, S. Popescu, D. Rohrlich
We present a possible scheme to tamper with non-local quantum correlations in a way that is consistent with relativistic causality, but goes beyond quantum mechanics. A non-local `…
Quantum Back Reaction on a Classical Field
R. Brout, S. Massar, S. Popescu +2
We show how to apply post selection in the context of weak measurement of Aharonov and collaborators to construct the quantum back reaction on a classical field. The particular cas…
