Qubit Motion as a Microscopic Model for the Dynamical Casimir Effect
Andrés Agustí, Laura García-Álvarez, Enrique Solano +1
The generation of photons from the vacuum by means of the movement of a mirror is known as the dynamical Casimir effect (DCE). In general, this phenomenon is effectively described…

Efficient simulatability of continuous-variable circuits with large Wigner negativity
Laura García-Álvarez, Cameron Calcluth, Alessandro Ferraro +1
Discriminating between quantum computing architectures that can provide quantum advantage from those that cannot is of crucial importance. From the fundamental point of view, estab…

From the Bloch sphere to phase space representations with the Gottesman-Kitaev-Preskill encoding
L. García-Álvarez, A. Ferraro, G. Ferrini
In this work, we study the Wigner phase-space representation of qubit states encoded in continuous variables (CV) by using the Gottesman-Kitaev-Preskill (GKP) mapping. We explore a…
