Motion and gravity effects in the precision of quantum clocks
Joel Lindkvist, Carlos Sabín, Göran Johansson +1
We show that motion and gravity affect the precision of quantum clocks. We consider a localised quantum field as a fundamental model of a quantum clock moving in spacetime and show…
Scattering of coherent pulses on a two-level system - single-photon generation
Joel Lindkvist, Göran Johansson
In this work, we consider a two-level system (TLS) coupled to a one-dimensional continuum of bosonic modes in a transmission line. Using the master equation approach, a method for…
Twin paradox with macroscopic clocks in superconducting circuits
Joel Lindkvist, Carlos Sabín, Ivette Fuentes +4
We propose an implementation of a twin paradox scenario in superconducting circuits, with velocities as large as a few percent of the speed of light. Ultrafast modulation of the bo…
