Comment on ``Protective measurements of the wave function of a single squeezed harmonic-oscillator state''
Y. Aharonov, L. Vaidman
Alter and Yamamoto [Phys. Rev. A 53, R2911 (1996)] claimed to consider ``protective measurements'' [Phys. Lett. A 178, 38 (1993)] which we have recently introduced. We show that th…
Realistic experiments for measuring the wave function of a single particle
S. Nussinov
We suggest scattering experiments which implement the concept of ``protective measurements'' allowing the measurement of the complete wave function even when only one quantum syste…
Thermodynamics and the Measure of Entanglement
Sandu Popescu, Daniel Rohrlich
We point out formal correspondences between thermodynamics and entanglement. By applying them to previous work, we show that entropy of entanglement is the unique measure of entang…
On Schizophrenic Experiences of the Neutron or Why We Should Believe in the Many-Worlds Interpretation of Quantum Theory
Lev Vaidman
This is a philosophical paper in favor of the Many-Worlds Interpretation (MWI) of quantum theory. The concept of the ``measure of existence of a world'' is introduced and some diff…
Applications of the Complex Geometric "Phase" for Meta-stable Systems
S. Massar
Garrison and Wright showed that upon undergoing cyclic quantum evolution a meta-stable state acquires both a geometric phase and a geometric decay probability. This is described by…
Error Prevention Scheme with Four Particles
Lev Vaidman, Lior Goldenberg, Stephen Wiesner
It is shown that a simplified version of the error correction code recently suggested by Shor exhibits manifestation of the quantum Zeno effect. Thus, under certain conditions, pro…
