Coherent population trapping with a controlled dissipation: applications in optical metrology

Coto, Raúl [Univ Mayor, Santiago, Chile]; Nicolás, L.; Delord, T.; Jamonneau, P.; Maze, J.; Jacques, V.; Hetet, G. (IOP PUBLISHING LTD, 2018)

We analyze the properties of a pulsed coherent population trapping protocol that uses a controlled decay from the excited state in a Lambda-level scheme. We study this problem analytically and numerically and find regimes ...
Ground-state cooling of a nanomechanical oscillator with N spins

Coto, Raúl [Univ Mayor, Santiago, Chile]; Orszag, Miguel [Univ Mayor, Santiago, Chile]; Montenegro, Victor; Eremeev, Vitalie (AMER PHYSICAL SOC, 2018)

It is typical of modern quantum technologies employing nanomechanical oscillators to demand few mechanical quantum excitations, for instance, to prolong coherence times of a particular task or to engineer a specific ...
