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…

Heisenberg limit in phase measurements: the threshold detection approach

D. I. Salykina, V. S. Liamin, V. L. Gorshenin +2

The ultimate precision of phase estimation is limited by the Heisenberg scaling $Δ ϕ_{0} = K / N$ , where $K \sim 1$ is a numerical prefactor and $N$ is the mean number of photons interact…
