Magnon Kerr effect in a strongly coupled cavity-magnon system
Yi-Pu Wang, Guo-Qiang Zhang, Dengke Zhang +6
We experimentally demonstrate magnon Kerr effect in a cavity-magnon system, where magnons in a small yttrium iron garnet (YIG) sphere are strongly but dispersively coupled to the p…
Energy localization enhanced ground-state cooling of mechanical resonator from room temperature in optomechanics using a gain cavity
Yu-Long Liu, Yu-xi Liu
When a gain system is coupled to a loss system, the energy usually flows from the gain system to the loss one. We here present a counterintuitive theory for the ground-state coolin…
Phonon blockade in a nanomechanical resonator resonantly coupled to a qubit
Xun-Wei Xu, Ai-Xi Chen, Yu-xi Liu
We study phonon statistics in a nanomechanical resonator (NAMR) which is resonantly coupled to a qubit. We find that there are two different mechanisms for phonon blockade in such…
Method for identifying electromagnetically induced transparency in a tunable circuit quantum electrodynamics system
Qi-Chun Liu, Tie-Fu Li, Xiao-Qing Luo +9
Electromagnetically induced transparency (EIT) has been realized in atomic systems, but fulfilling the EIT conditions for artificial atoms made from superconducting circuits is a m…
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…
