Macroscopic Bell state between a millimeter-sized spin system and a superconducting qubit
Da Xu, Xu-Ke Gu, Yuan-Chao Weng +4
Entanglement is a fundamental property in quantum mechanics that systems share inseparable quantum correlation regardless of their mutual distances. Owing to the fundamental signif…
Generating Bell states and -partite states of long-distance qubits in superconducting waveguide QED
Guo-Qiang Zhang, Wei Feng, Wei Xiong +3
We show how to generate Bell states and -partite states of long-distance superconducting (SC) qubits in a SC waveguide quantum electrodynamical (QED) system, where SC qubits…
Observation of a superradiant phase transition with emergent cat states
Ri-Hua Zheng, Wen Ning, Ye-Hong Chen +15
Superradiant phase transitions (SPTs) are important for understanding light-matter interactions at the quantum level, and play a central role in criticality-enhanced quantum sensin…
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…
Duality Symmetry of Quantum Electrodynamics and Magnetic Charges
Li-Ping Yang, Dazhi Xu
The duality symmetry between electricity and magnetism hidden in classical Maxwell equations suggests the existence of dual charges, which have usually been interpreted as magnetic…
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…
