Improvement of phase sensitivity in SU(1,1) interferometer via a Kerr nonlinear
Shoukang Chang, Wei Ye, Huan Zhang +3
We propose a theoretical scheme to enhance the phase sensitivity by introducing a Kerr nonlinear phase shift into the traditional SU(1,1) interferometer with a coherent state input…

Operator transpose within normal ordering and its applications for quantifying entanglement
Liyun Hu, Luping Zhang, Xiaoting Chen +3
Partial transpose is an important operation for quantifying the entanglement, here we study the (partial) transpose of any single (two-mode) operators. Using the Fock-basis expansi…
