Título:Multimode parametric amplification of the quantum vacuum for quantum computing
Resumen: The Dynamical Casimir Effect (DCE) consists in the generation of photons out of the vacuum of a quantum field by means of the non-adiabatic modulation of boundary conditions -e.g. a mirror oscillating at speeds comparable to the speed of light. Predicted in 1970, an experimental demonstration remained elusive until 2011, when it was implemented in a superconducting circuit architecture. In addition to its fundamental interest, it has been shown that the radiation generated in the DCE displays bipartite and multipartite entanglement as well as other forms of quantum correlations, which poses the question of its utility as a resource for the heralded quantum-technological revolution. In this talk, we establish a bridge between multimode parametric amplification induced by the modulation of boundary conditions – for which DCE is a paradigmatic case- and quantum computing devices.
