Exceptional Point and Cross-Relaxation Effect in a Hybrid Quantum System
Guo-Qiang Zhang, Zhen Chen, Da Xu +7
Exceptional points (EPs) are exotic degeneracies of non-Hermitian systems, where the eigenvalues and the corresponding eigenvectors simultaneously coalesce in parameter space, and…
Phase-controlled pathway interferences and switchable fast-slow light in a cavity-magnon polariton system
Jie Zhao, Longhao Wu, Tiefu Li +4
We study the phase controlled transmission properties in a compound system consisting of a 3D copper cavity and an yttrium iron garnet (YIG) sphere. By tuning the relative phase of…
Photon-Dressed Bloch-Siegert Shift in an Ultrastrongly Coupled Circuit Quantum Electrodynamical System
Shuai-Peng Wang, Guo-Qiang Zhang, Yimin Wang +5
A cavity quantum electrodynamical (QED) system beyond the strong-coupling regime is expected to exhibit intriguing quantum phenomena. Here we report a direct measurement of the pho…
An analytical double-unitary-transformation approach for strongly and periodically driven three-level systems
Yingying Han, Xiao-Qing Luo, Tie-Fu Li +1
Floquet theory combined with the generalized Van Vleck nearly degenerate perturbation theory, has been widely employed for studying various two-level systems that are driven by ext…
Quantum Simulation of the Fermion-Boson Composite Quasi-Particles with a Driven Qubit-Magnon Hybrid Quantum System
Yi-Pu Wang, Guo-Qiang Zhang, Da Xu +4
We experimentally demonstrate strong coupling between the ferromagnetic magnons in a small yttrium-iron-garnet (YIG) sphere and the drive-field-induced dressed states of a supercon…
Time-domain grating with a periodically driven qutrit
Yingying Han, Xiao-Qing Luo, Tie-Fu Li +5
Physical systems in the time domain may exhibit analogous phenomena in real space, such as time crystals, time-domain Fresnel lenses, and modulational interference in a qubit. Here…
