The paper deals with the fundamental question of whether an environment, defined as a quantum system with an arbitrarily large or infinite number of unobservable degrees of freedom, is necessary or not to enforce quantum decoherence on quantum measuring instruments. The paper gives an unambiguous answer to the question as summarized by its Abstract: Current… Read More »
This blogpost is aimed to explain some portions of our paper “Dissipative preparation of phase and number squeezed states using ultracold atoms” (Phys. Rev. A 89, 013620 (2014)), authored by Gentaro Watanabe, Harri Makela, Sebastian Diehl, Markus Oberthaler and myself. At the time of the collaboration, Prof. Watanabe was based at the Asia Pacific Center… Read More »
The paper deals with the fundamental question of whether an environment is necessary or not to enforce quantum decoherence on quantum measuring instruments. The paper gives an unambiguous answer to the question as summarized by its Abstract: Current quantum orthodoxy claims that the statistical collapse of the wave-function arises from the interaction of the measuring… Read More »
Introduction We, physicists, work with our operators very differently from mathematicians. We are unencumbered by rigor and our mathematics proceeds with the motivation to forge ahead to gain insight as quickly as possible. Only later when our results are meaningful that we bother to step back and ask ourselves if our steps in reaching our… Read More »
