WebbAs the total system is closed, we can write its unitary evolution as (3.3) ϱ S B ( t) = U ( t) ϱ S B ( 0) U † ( t), with U ( t) = exp [ − i H t]. If we now take the partial trace over the environment in the equation above, we have: (3.4) ϱ S ( t) = T r B { U ( t) ϱ S B ( 0) U † ( t) } = T r B { U ( t) ϱ S ( 0) ⊗ ϱ B U † ( t) } ≡ Λ t ϱ S ( 0). WebbWe assess the effect of the heat radiation emitted by mesoscopic particles on their ability to show interference in a double-slit arrangement. The analysis is based on a stationary, phase-space-based description of matter-wave interference in the presence of momentum-exchange-mediated decoherence. phil johnson blacksmith

http://park.itc.u-tokyo.ac.jp/motohiko-ezawa/ezawa/lecture.html The Lindblad master equation describes the evolution of various types of open quantum systems, e.g. a system weakly coupled to a Markovian reservoir. Note that the H appearing in the equation is not necessarily equal to the bare system Hamiltonian, but may also incorporate effective unitary dynamics arising from the system-environment interaction. A heuristic derivation, e.g., in the notes by Preskill, begins with a more general form of an open q… phil johnson christian singerWebbThe Lindblad equation is an evolution equation for the density matrix in quantum theory.

WebbIn this paper, we consider the application of quantum reservoir engineering in quantum metrology. More precisely, we are concerned with a system setup where a sequence of atoms constructing the “time-varying” quantum reservoir interact, in turn, with the trapped field in a cavity through the Jaynes–Cummings Hamiltonian. In … WebbTraditional loss formulas are composed of network parameters and in terms of the generator’s real power outputs. These formulas are derived by several assumptions, but these basic assumptions sacrifice accuracy. In this study, a new expression for the loss formula is proposed to improve the shortcomings of traditional loss formulas.
