Broadening the high sensitivity range of squeezing-assisted interferometers by means of two-channel detection
Gaurav Shukla, Dariya Salykina, Gaetano Frascella +3
For a squeezing-enhanced SU(2) interferometer, we theoretically investigate the possibility to broaden the phase range of sub-shot-noise sensitivity. We show that this goal can be…

Generation of non-classical optical fields by a beam splitter with second-order nonlinearity
Hari Prakash, Devendra Kumar Mishra
We propose quantum-mechanical model of a beam splitter with second-order nonlinearity and show that non-classical features such as squeezing and sub-Poissonian photon statistics of…
