Gaussian superpositions for bosonic encodings
Federico Centrone, Juan Pablo Paz, Augusto Roncaglia
Non-Gaussian bosonic states are ubiquitous in interacting light--matter systems, many-body platforms, and relativistic quantum field settings, but their quantitative characterizati…
Squeezed quantum multiplets: properties and phase space representation
Juan Pablo Paz, Corina Révora, Christian Tomás Schmiegelow
We define and study the properties of ``squeezed quantum multiplets''. Ordinary multiplets are sets of -orthonormal quantum states formed by superpositions of states squeezed al…
Controlled-squeeze gate in superconducting quantum circuits
Nicolás F. Del Grosso, Rodrigo G. Cortiñas, Paula I. Villar +2
We present a method to prepare non-classical states of the electromagnetic field in a microwave resonator. It is based on a controlled gate that applies a squeezing operation on a…
Defining coherent states: why must they be eigenstates of the annihilation operator?
Juan Pablo Paz, Augusto J. Roncaglia
This is a pedagogical paper where we present a physically motivated approach to introduce the coherent states of a harmonic oscillator from which it is simple to rigorously derive…
