Decoherence and the transition from quantum to classical -- REVISITED

Wojciech H. Zurek

Abstract

The environment surrounding a quantum system can, in effect, monitor some of the systems observables. As a result, the eigenstates of these observables continuously decohere and can behave like classical states.

    • As a former quantum physicist who has just decided to go back into quantum computing, this was my take as well: Introductory quantum physics courses may still include wave-function collapse and all that nonsense, but I have not met many physicists who use this as a mental model.…

    • > inflating small fragments HN comments don't lend themselves well to long-form writing. But in this case it wasn't really necessary to go past that one small fragment to see that Motl had not in fact paid attention to the details because he's attacking a straw man. > Your…

    • My paper is based on this one: http://arxiv.org/pdf/quant-ph/9605002v2.pdf I don't know if that exact paper was ever published, but an earlier version was formally published here: C. H. Adami and N. J. Cerf, “Information Theory of Quantum Entanglement and Measurement,” Physica D…
