Transitionless quantum drivings for the harmonic oscillator
J. G. Muga, X. Chen, Ibáñez +2
Two methods to change a quantum harmonic oscillator frequency without transitions in a finite time are described and compared. The first method, a transitionless-tracking algorithm…
Zeno physics in ultrastrong circuit QED
I. Lizuain, J. Casanova, J. J. Garcia-Ripoll +2
We study the Zeno and anti-Zeno effects in a superconducting qubit interacting strongly and ultrastrongly with a microwave resonator. Using a model of a frequently measured two-lev…
Short-time-interaction quantum measurement through an incoherent mediator
J. Casanova, G. Romero, I. Lizuain +4
We develop a theory of indirect measurements where a probe is able to read, in short interaction times, the quantum state of a remote system through an incoherent wall. The probe a…
Low velocity limits of cold atom clocks
J. Muñoz, I. Lizuain, J. G. Muga
Fundamental low-energy limits to the accuracy of quantum clock and stopwatch models in which the clock hand motion is activated by the presence of a particle in a region of space h…
