Entangling Superconducting Qubits through an Analogue Wormhole

Marcelo Castellanos2021-02-12T10:07:58+01:00Tags: Astronomy & Astrophysics; Physics, Particles & Fields. |

Authors: Sabin, Carlos Contribution: Article Journal: UNIVERSE Publication date: 2020/09/09 DOI: 10.3390/universe6090149 Abstract: We propose an experimental setup to test the effect of curved spacetime upon the extraction of entanglement from the quantum field vacuum to a pair of two-level systems. We consider two superconducting qubits coupled to a dc-SQUID array embedded into an open microwave [...]
