Non-gaussian Entanglement Swapping between Three-Mode Spontaneous Parametric Down Conversion and Three Qubits
A. Agustí Casado, C. Sabín
In this work we study the production and swapping of non-gaussian multipartite entanglement in a setup containing a parametric amplifier which generates three photons in different…
Causality in a qubit-based quantum switch
Carlos Sabín
We introduce a qubit-based version of the quantum switch, consisting in a variation of the Fermi problem. Two qubits start in a superposition state where one qubit is excited and t…
Digital quantum simulation of beam splitters and squeezing with IBM quantum computers
Paula Cordero Encinar, Andrés Agustí, Carlos Sabín
We present results on the digital quantum simulations of beam-splitter and squeezing interactions. The bosonic hamiltonians are mapped to qubits and then digitalized in order to im…
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…
Entangling superconducting qubits through an analogue wormhole
Carlos Sabín
We propose an experimental setup to test the role of curved spacetime on entanglement extraction from the vacuum of a quantum field to a pair of artificial atoms. In particular, we…
Digital quantum simulation of linear and nonlinear optical elements
Carlos Sabín
We provide a recipe for the digitalization of linear and nonlinear quantum optics in networks of superconducting qubits. By combining digital techniques with boson-qubit mappings w…
