Environment induced decoherence for Markovian evolutions

R Carbone, E Sasso, V Umanità - Journal of Mathematical Physics, 2015 - pubs.aip.org
We study environmental decoherence for a quantum Markov semigroup T acting on an
arbitrary von Neumann algebra M⁠. In particular, we analyze the relationships between the …

[HTML][HTML] Decoherence in excited atoms by low-energy scattering

DA Quiñones, B Varcoe - Atoms, 2016 - mdpi.com
We describe a new mechanism of decoherence in excited atoms as a result of thermal
particles scattering by the atomic nucleus. It is based on the idea that a single scattering will …

Detection of space-time perturbations with quantum-enhanced metrology

DA Quiñones Valles - 2017 - etheses.whiterose.ac.uk
We present a new model of atomic decoherence by space-time perturbations. We propose
that decoherence will arise as a result of two possible effects that gravitational fluctuations …
