On two recent proposals for witnessing nonclassical gravity
Michael J. W. Hall, Marcel Reginatto
Two very similar proposals have been made recently for witnessing nonclassical features of gravity, by Bose et al. and by Marletto and Vedral. However, while these proposals are as…
Simultaneous continuous measurement of non-commuting observables: quantum state correlations
Areeya Chantasri, Juan Atalaya, Shay Hacohen-Gourgy +3
We consider the temporal correlations of the quantum state of a qubit subject to simultaneous continuous measurement of two non-commuting qubit observables. Such qubit state correl…
A single-atom 3D sub-attonewton force sensor
V. Blūms, M. Piotrowski, M. I. Hussain +5
All physical interactions are mediated by forces. Ultra-sensitive force measurements are therefore a crucial tool for investigating the fundamental physics of magnetic, atomic, qua…
Coarse graining a non-Markovian collisional model
Nadja K. Bernardes, Andre R. R. Carvalho, C. H. Monken +1
The dynamics of systems subjected to noise is called Markovian in the absence of memory effects, i.e. when its immediate future only depends on its present. Time correlations in th…
