From decoherence-free channels to decoherence-free and quasi-free subspaces within bosonic dissipative networks
(IOP PUBLISHING LTD, 2011)
We present a technique to build, within a dissipative bosonic network, decoherence-free channels (DFCs): a group of normal-mode oscillators with null effective damping rates. We verify that the states protected within the ...
Protecting The Root Swap Operation From General And Residual Errors By Continuous Dynamical Decoupling
(AMER PHYSICAL SOCCOLLEGE PK, 2015)
Continuous dynamical decoupling and decoherence-free subspaces for qubits with tunable interaction
(2019-05-01)
Protecting quantum states from the decohering effects of the environment is of great importance for the development of quantum computation devices and quantum simulators. Here, we introduce a continuous dynamical decoupling ...
The double Caldeira-Leggett model: Derivation and solutions of the master equations, reservoir-induced interactions and decoherence
(ELSEVIER SCIENCE BV, 2010)
In this paper we analyze the double Caldeira-Leggett model: the path integral approach to two interacting dissipative harmonic oscillators. Assuming a general form of the interaction between the oscillators, we consider ...
DECOHERENCE-FREE SUBSPACES FOR OPEN QUANTUM RANDOM WALKS ON GRAPHS
(Publicaciones académicas Ltd., 2016)
We study decoherence-free subspaces in a type of Quantum Markov Semigroups called continuous-time open quantum random walks on graphs. We measure the temporary changes of quantum correlations using geometric quantum discord ...
Sudden death of entanglement in fermionic systems under collective decoherence
(IOP Publishing, 2020-08)
We analyze the dynamics of entanglement due to decoherence in asystem of two identical fermions with spin 3/2 interacting with a global bosonicenvironment. We make use of an appropriate measure of the so-called ...
Emaranhamento: caracterização, manipulação e consequências
(Universidade Federal de Minas GeraisUFMG, 2005-04-15)
Entanglement is characterized, to the best knowledge of these days, from bipartite pure states to multipartite mixed states, and including the problems of di erent tensor product structures determination for a given quantum ...
