A Fixed Point Result for Environment-Induced Semigroups | A. M. Lisewski
; | Date: |
11 Nov 2002 | Subject: | quant-ph | Abstract: | Based on the environment induced semigroup approach to the quantum measurement process, we show that a certain class of these semigroups, referred to as contractive uniformly $k$-Lipschitzian semigroups, exhibit a fixed point property. With regard to the quantum measurement problem, semigroups of this kind ensure decoherence and the selection of a single state from the familiy of pointer states. In fact, the common fixed point is the selected state. | Source: | arXiv, quant-ph/0211054 | Services: | Forum | Review | PDF | Favorites |
