Measuring a quantum system without problems
Marco Falconi, Clotilde Fermanian Kammerer, Raphaël Gautier
The process of measuring quantum observables has been plagued, since the inception of quantum mechanics, by the so-called measurement problem: it is impossible to read a definite o…

Quasi-classical Limit of a Spin Coupled to a Reservoir
Michele Correggi, Marco Falconi, Michele Fantechi +1
A spin (qubit) is in contact with a bosonic reservoir. The state of the reservoir contains a parameter {\varepsilon} interpolating between quantum and classical reservoir features.…
