Simulating spin measurement with a finite heat bath model for the environment
Thomas Dittrich, Óscar Rodrí guez, Carlos Viviescas
Spin measurement is studied as a unitary time evolution of the spin coupled to an environment representing the meter and the apparatus. Modelling the environment as a heat bath com…
Fuzzy measurements and coarse graining in quantum many-body systems
Carlos Pineda, David Davalos, Carlos Viviescas +1
Using the quantum map formalism, we provide a framework to construct fuzzy and coarse grained quantum states of many-body systems that account for limitations in the resolution of…
Parametrization and optimization of Gaussian non-Markovian unravelings for open quantum dynamics
Nina Megier, Walter T. Strunz, Carlos Viviescas +1
We derive a family of Gaussian non-Markovian stochastic Schrödinger equations for the dynamics of open quantum systems. The different unravelings correspond to different choices of…
Average entanglement dynamics in open two-qubit systems with continuous monitoring
Ivonne Guevara, Carlos Viviescas
We present a comprehensive implementation of the quantum trajectory theory for the description of the entanglement dynamics in a Markovian open quantum system made of two qubits. W…
A statistical portrait of the entanglement decay of two-qubit memories
Karen M. Fonseca-Romero, Julián Martínez-Rincón, Carlos Viviescas
We present a novel approach to the study of entanglement decay, which focuses on collective properties. As an example, we investigate the entanglement decay of a two-qubit system,…
Quantifying entanglement in multipartite conditional states of open quantum systems by measurements of their photonic environment
Juan Diego Urbina, Walter T. Strunz, Carlos Viviescas
A key lesson of the decoherence program is that information flowing out from an open system is stored in the quantum state of the surroundings. Simultaneously, quantum measurement…
