Significant enhancement in refrigeration and entanglement in auxiliary-cavity-assisted optomechanical systems
Deng-Gao Lai, Wei Qin, Bang-Pin Hou +2
We propose how to achieve significantly enhanced quantum refrigeration and entanglement by coupling a pumped auxiliary cavity to an optomechanical cavity. We obtain both analytical…
Generating Large Cats with Nine Lives: Long-Lived Macroscopically Distinct Superposition States in Atomic Ensembles
Wei Qin, Adam Miranowicz, Hui Jing +1
We propose to create and stabilize long-lived macroscopic quantum superposition states in atomic ensembles. We show that using a fully quantum parametric amplifier can cause the si…
Fast binomial-code holonomic quantum computation with ultrastrong light-matter coupling
Ye-Hong Chen, Wei Qin, Roberto Stassi +2
We propose a protocol for bosonic binomial-code nonadiabatic holonomic quantum computation in a system composed of an artificial atom ultrastrongly coupled to a cavity resonator. I…
Two-level systems with periodic -step driving fields: Exact dynamics and quantum state manipulations
Zhi-Cheng Shi, Ye-Hong Chen, Wei Qin +4
In this work, we derive exact solutions of a dynamical equation, which can represent all two-level Hermitian systems driven by periodic -step driving fields. For different physi…
Tunable optomechanically induced transparency by controlling the dark-mode effect
Deng-Gao Lai, Xin Wang, Wei Qin +3
We study tunable optomechanically induced transparency by controlling the dark-mode effect induced by two mechanical modes coupled to a common cavity field. This is realized by int…
Shortcuts to Adiabaticity for the Quantum Rabi Model: Efficient Generation of Giant Entangled cat States via Parametric Amplification
Ye-Hong Chen, Wei Qin, Xin Wang +2
We propose a method for the fast generation of nonclassical ground states of the Rabi model in the ultrastrong and deep-strong coupling regimes via the shortcuts-to-adiabatic (STA)…
