Bose polarons as relativistic Unruh-DeWitt detectors: Entanglement harvesting from Bose-Einstein condensates
T. Rick Perche, Francesco Gozzini, Markus K. Oberthaler
We show that a bound impurity in a Bose-Einstein condensate can be directly mapped to an Unruh-DeWitt detector interacting with a relativistic quantum field. We provide explicit ex…
Subsystem entanglement and separability in quantum reference frames
T. Rick Perche, Natália Salomé Móller, Guilherme Franzmann
We find a necessary condition for subsystems to become entangled after a quantum reference frame transformation. We then distinguish between subsystems that admit separable descrip…
Finite-size clocks in quantum field theory and the twin paradox
Matheus H. Zambianco, T. Rick Perche
Vacuum fluctuations in quantum field theory impose fundamental limitations on our ability to measure time at arbitrarily short scales. To investigate the impact of universal quantu…
Trajectory-Protected Quantum Computing
Barbara Šoda, Pierre-Antoine Graham, T. Rick Perche +1
We introduce a novel method that simultaneously isolates a quantum computer from decoherence and enables the controlled implementation of computational gates. We demonstrate a quan…
State updates and useful qubits in relativistic quantum information
José Polo-Gómez, T. Rick Perche, Eduardo Martín-Martínez
We address the longstanding challenge of consistently updating quantum states after selective measurements in a relativistic spacetime. Standard updates along the future lightcones…
