Non-Gaussian entanglement swapping between three-mode spontaneous parametric down-conversion and three qubits

2023-02-21T13:37:15+01:00Tags: , , |

Authors: Casado, A. Agusti; Sabin, C. Journal: PHYSICAL REVIEW A Publication date: 2022/02/03 DOI: 10.1103/PhysRevA.105.022401 Abstract: 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 modes coupled to three qubits. We prove that the entanglement generated in this [...]

Authors: Garcia-Abenza, A.; No, J. M. Journal: EUROPEAN PHYSICAL JOURNAL C Publication date: 2022/02/01 DOI: 10.1140/epjc/s10052-022-10089-3 Abstract: High-energy ( )gamma gamma colliders constitute a potential running mode of future lepton colliders such as the ILC and CLIC. We study the sensitivity of a high-energy gamma gamma collider to the Higgs portal scenario to a hidden [...]
