Amplification of the coupling strength in a hybrid quantum system
Wei Xiong, Yueyin Qiu, Lian-Ao Wu +1
Realization of strong coupling between two different quantum systems is important for fast transferring quantum information between them, but its implementation is difficult in som…
Single-photon-driven high-order sideband transitions in an ultrastrongly coupled circuit quantum electrodynamics system
Zhen Chen, Yimin Wang, Tiefu Li +8
We report the experimental observation of high-order sideband transitions at the single-photon level in a quantum circuit system of a flux qubit ultrastrongly coupled to a coplanar…
Four-junction superconducting circuit
Yueyin Qiu, Wei Xiong, Xiao-Ling He +2
We develop a theory for the quantum circuit consisting of a superconducting loop interrupted by four Josephson junctions and pierced by a magnetic flux (either static or time-depen…
Cross-Kerr effect on an optomechanical system
Wei Xiong, Da-Yu Jin, Yueyin Qiu +2
We study cross-Kerr (CK) effect on an optomechanical system driven by two-tone fields. We show that in the presence of the CK effect, a bistable behavior of the mean photon number…
Coupling spin ensembles via superconducting flux qubits
Yueyin Qiu, Wei Xiong, Lin Tian +1
We study a hybrid quantum system consisting of spin ensembles and superconducting flux qubits, where each spin ensemble is realized using the nitrogen-vacancy centers in a diamond…
