Tachyonic quench in a free bosonic field theory
Sebastian Montes, Javier Rodríguez-Laguna, Germán Sierra
We present a characterization of a bosonic field theory driven by a free (Gaussian) tachyonic Hamiltonian. This regime is obtained from a theory describing two coupled bosonic fiel…
Five Experimental Tests on the 5-Qubit IBM Quantum Computer
Diego García-Martín, Germán Sierra
The 5-qubit quantum computer prototypes that IBM has given open access to on the cloud allow the implementation of real experiments on a quantum processor. We present the results o…
The role of short periodic orbits in quantum maps with continuous openings
Carlos A. Prado, Gabriel G. Carlo, R. M. Benito +1
We apply a recently developed semiclassical theory of short periodic orbits to the continuously open quantum tribaker map. In this paradigmatic system the trajectories are partiall…
Dynamical aspects in the Quantizer-Dequantizer formalism
Florio M. Ciaglia, Fabio Di Cosmo, Alberto Ibort +1
The use of the quantizer-dequantizer formalism to describe the evolution of a quantum system is reconsidered. We show that it is possible to embed a manifold in the space of quantu…
Dynamical Vector Fields on the Manifold of Quantum States
Florio M. Ciaglia, Fabio Di Cosmo, Alberto Ibort +2
In this paper we shall consider the stratified manifold of quantum states and the vector fields which act on it. In particular, we show that the infinitesimal generator of the GKLS…
Frequency-resolved Monte Carlo
Juan Camilo López Carreño, Elena del Valle, Fabrice P. Laussy
We adapt the Quantum Monte Carlo method to the cascaded formalism of quantum optics, allowing us to simulate the emission of photons of known energy. Statistical processing of the…
