The generation of (Bell-)nonlocal correlations, i.e., correlations leading to the violation of a Bell-like inequality, requires the usage of a nonlocal resource, such as an entangled state. When given a correlation (a ...

Given a set of local dynamics, are they compatible with a global dynamics? We systematically formulate these questions as quantum channel marginal problems. These problems are strongly connected to the generalization of ...

In this project, two methods have been analyzed to obtain the information, previously com-pressed, through a quantum channel. Information travels through qubits, which are the unit of information in the world of quantum ...

In this work we experimentally and theoretically characterize the converted signal and the noise level of a quantum frequency conversion (QFC) device implemented for frequency down conversion from the visible to telecommunication ...

The ground-state properties of one-dimensional spin polarized hydrogen, deuterium and tritium at zero temperature are obtained by means of Diffusion Monte Carlo calculations (DMC). The equations of state of the three ...

A self-accelerating electronic wave packet can acquire a phase akin to the Aharonov–Bohm effect, but in the absence of a magnetic field.

We have studied how the ground state and the one-body density distribution of a one-dimensional system of bosons trapped by a harmonic oscillator potential depend on the repulsive interaction between the bosons. This study ...

We develop a numerical simulator to solve the time-dependent Schrödinger equation (TDSE) to simulate strong field ionization of a single electron under the influence of a one-dimensional separable potential. We use the ...

We study the properties of a single impurity in a dilute Bose gas, a Bose polaron, using the functional renormalization group. We use an ansatz for the effective action motivated by a derivative expansion, and we compute ...
