Maximally non-Markovian quantum dynamics without environment-to-system backflow of information
(American Physical Society, 2018-05)
The degree of non-Markovianity allows one to characterize quantum evolutions that depart from a Markovian regime in a similar way as the Schmidt number measures the degree of entanglement of pure states. Maximally non-Markovian ...
Why entanglement of formation is not generally monogamous
(2013-03-13)
Unlike correlation of classical systems, entanglement of quantum systems cannot be distributed at will: if one system A is maximally entangled with another system B, it cannot be entangled at all with a third system C. ...

Dynamical dimerization phase in Jaynes-Cummings lattices
(IOP Publishing, 2020)
We report on an emergent dynamical phase of a strongly-correlated light-matter system, which is governed by dimerization processes due to short-range and long-range two-body interactions. The dynamical phase is characterized ...
Role of initial conditions in the dynamics of quantum glassy systems
(IOP Publishing, 2019-02-25)
We set the formalism to study the way in which the choice of canonical equilibrium initial conditions affect the real-time dynamics of quantum disordered models. We use a path integral formulation on a time contour with ...
Enhanced precision of low-temperature quantum thermometry via dynamical control
(Asociación Física Argentina, 2019)
Precise probing of quantum systems is one of the keys to progress in diverse quantum technologies, includingquantum metrology, quantum information processing and quantum many-body manipulations. We consider athermometer ...
Maximizing information on the environment by dynamically controlled qubit probes
(American Physical Society, 2016-01)
We explore the ability of a qubit probe to characterize unknown parameters of its environment. By resorting to the quantum estimation theory, we analytically find the ultimate bound on the precision of estimating key ...
