Decoherence control by quantum decoherence itself. [PDF]
Sci Rep, 2015 AbstractWe propose a general approach of protecting a two-level system against decoherence via quantum engineering of non-classical multiple superpositions of coherent states in a non-Markovian reservoir. The scheme surprisingly only uses the system-environment interaction responsible for the decoherence and projective measurements of the two-level ...

Decoherence on staggered quantum walks [PDF]
Physical Review A, 2022 Decoherence phenomenon has been widely studied in different types of quantum walks. In this work we show how to model decoherence inspired by percolation on staggered quantum walks. Two models of unitary noise are described: breaking polygons and breaking vertices.

Scanning quantum decoherence microscopy [PDF]
Nanotechnology, 2009 The use of qubits as sensitive magnetometers has been studied theoretically and recent demonstrated experimentally. In this paper we propose a generalisation of this concept, where a scanning two-state quantum system is used to probe the subtle effects of decoherence (as well as its surrounding electromagnetic environment). Mapping both the Hamiltonian

, 2022 A study of continuous measurement and quantum decoherence is presented in this work. Starting from the Schrödinger- von Neumann equation and developing it, a set of stochastic equations will be obtained such that they describe the behaviour of a system of few degrees of freedom affected by a bath of many degrees of freedom that is interacting with it ...

Decoherence and quantum fluctuations [PDF]
Physical Review B, 1997 We show that the zero-point fluctuations of the intrinsic electromagnetic environment limit the phase coherence time in all mesoscopic systems at low temperatures. We derive this quantum noise limited dephasing time and its temperature dependence in the crossover to the thermal regime. Our results agree well with most experiments in 1D systems.

Quantifying Decoherence via Increases in Classicality
Entropy, 2021 As a direct consequence of the interplay between the superposition principle of quantum mechanics and the dynamics of open systems, decoherence is a recurring theme in both foundational and experimental exploration of the quantum realm.

On the effect of decoherence on quantum tunnelling
SN Applied Sciences, 2021 This work proposes a series of quantum experiments that can, at least in principle, allow for examining microscopic mechanisms associated with decoherence.
