Towards experimental entanglement harvesting in superconducting circuits

Adam Teixido-Bonfill

Entanglement harvesting is the surprising prediction that two quantum systems can become entangled by locally interacting with a quantum field, even if the two systems are far apart and never directly interact. Moreover, this can occur even if the field is in its vacuum state. In relativistic quantum information, entanglement harvesting is typically modeled using Unruh-DeWitt (UDW) particle detectors.

In this talk, we show how to extend the standard UDW detector model to better match a proposed realization of entanglement harvesting in superconducting circuits. The experiment consists of a pair of tunable superconducting qubits that interact with one-dimensional quantum fields (transmission lines). We investigate how these experimental features impact entanglement harvesting, paving the way to implement this protocol in the lab.
