Amplified quantum non-demolition measurements of optical quadratures using quadratic nonlinearity
D. I. Salykina, V. S. Liamin, P. R. Sharapova +1
Quantum non-demolition (QND) measurement is a special technique that allows to evade quantum back-action. In this paper, we propose a new QND measurement scheme of the optical fiel…

Intracavity squeezing for Kerr QND Measurement scheme
Dariya Salykina, Stepan Balybin, Farid Ya. Khalili
In Ref. [Phys. Rev. A 108, 053708], the scheme of quantum non-demolition measurement of optical quanta that uses a resonantly enhanced Kerr nonlinearity in the optical microresonat…

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…
