Nondeterministic ultrafast ground-state cooling of a mechanical resonator
Nondeterministic ultrafast ground-state cooling mechanical resonator
2014/5/28
We present a feasible scheme for the cooling of a mechanical resonator via projective measurements on an auxiliary flux qubit which interacts with it. We find that ground-state cooling can be achieved...
A Single Laser System for Ground State Cooling of 25-Mg+
Single Laser System Ground State Cooling 25-Mg+
2010/11/9
We present a single solid-state laser system to cool, coherently manipulate and detect $^{25}$Mg$^+$ ions. Coherent manipulation is accomplished by coupling two hyperfine ground state levels using a p...
Fast ground-state cooling of mechanical resonators with time-dependent optical cavities
Fast ground-state cooling mechanical resonators time-dependent optical cavities
2014/5/28
We propose a feasible scheme to cool down a mechanical resonator (MR) in a three-mirror cavity optomechanical system with controllable external optical driving fields. Under the Born-Oppenheimer appro...
