Quantum coherence in ultrastrong optomechanics
D. Hu, S. -Y. Huang, J. -Q. Liao +2
Ultrastrong light-matter interaction in an optomechanical system can result in nonlinear optical effects such as photon blockade. The system-bath couplings in such systems play an…
Enhanced interferometry using squeezed thermal states and even or odd states
Qing-Shou Tan, Jie-Qiao Liao, Xiaoguang Wang +1
We derive a general expression of the quantum Fisher information for a Mach-Zehnder interferometer, with the port inputs of an \emph{arbitrary} pure state and a squeezed thermal st…
Spectrometric reconstruction of mechanical-motional states in optomechanics
Jie-Qiao Liao, Franco Nori
We propose a spectrometric method to reconstruct the motional states of mechanical modes in optomechanics. This is achieved by detecting the single-photon emission and scattering s…
Steady-state Mechanical Squeezing in an Optomechanical System via Duffing Nonlinearity
Xin-You Lü, Jie-Qiao Liao, Lin Tian +1
Quantum squeezing in mechanical systems is not only a key signature of macroscopic quantum effects, but can also be utilized to advance the metrology of weak forces. Here we show t…
Tailorable couplings of a cantilever with a superconducting charge qubit: Quantum state engineering
Jie-Qiao Liao, Le-Man Kuang
We propose a theoretical scheme to realize tailorable couplings between a cantilever and a superconducting charge qubit. By tuning the controllable parameters of the qubit, both li…
