Two-mode light states before and after delocalized single-photon addition
Bo Lan, Hong-chun Yuan, Xue-xiang Xu
We studied the effect of delocalized single-photon addition (DPA) on two input modes containing four cases: two independent coherent states (CSs), two independent thermal states (T…

Multi-headed symmetrical superpositions of coherent states
Bo Lan, Xue-xiang Xu
Based on N different coherent states with equal weights and phase-space rotation symmetry, we introduce N-headed incoherent superposition states (NHICSSs) and N-headed coherent sup…

Quantum-enhanced SU(1,1) interferometry via a Fock state
Shuai Wang, Jian-Dong Zhang, Xue-Xiang Xu
In this paper, we derive a general expression of the quantum Fisher information of an SU(1,1) interferometer with an arbitrary state and a Fock state as inputs by the phase-averagi…
