Data processing over single-port homodyne detection to realize super-resolution and super-sensitivity
J. H. Xu, A. X. Chen, W. Yang +1
Performing homodyne detection at one port of squeezed-state light interferometer and then binarzing measurement data are important to achieve super-resolving and super-sensitive ph…
Experimental orthogonalization of highly overlapping quantum states with single photons
Gaoyan Zhu, Orsolya Kalman, Kunkun Wang +6
We experimentally realize a nonlinear quantum protocol on single-photon qubits with linear optical elements and appropriate measurements. The quantum nonlinearity is induced by pos…
Dispersive readout of a weakly coupled qubit via the parity-time-symmetric phase transition
Guo-Qiang Zhang, Yi-Pu Wang, J. Q. You
For some cavity-quantum-electrodynamics systems, such as a single electron spin coupled to a passive cavity, it is challenging to reach the strong-coupling regime. In such a weak-c…
An analytical variational method for the biased quantum Rabi model in the ultra-strong coupling regime
Bin-Bin Mao, Maoxin Liu, Wei Wu +3
An analytical variational method for the ground state of the biased quantum Rabi model in the ultra-strong coupling regime is presented. This analytical variational method can be o…
Variational generalized rotating-wave approximation in the two-qubit quantum Rabi model
Bin-Bin Mao, Liangsheng Li, Yimin Wang +4
We present an analytical method for the two-qubit quantum Rabi model. While still operating in the frame of the generalized rotating-wave approximation (GRWA), our method further e…
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…
