Overcoming standard quantum limit using a momentum measuring interferometer: publisher’s note

Open Access Open Access

Abstract

This publisher’s note contains corrections to Opt. Lett. 45, 1256 (2020) [CrossRef]  .

In Ref. [1], two of the display equations were incorrect. Equation (2) should have been

$${\Delta }p = \left\langle \sqrt {{{\left[T\left( {\hat F} \right)\right]}^\dagger }T\left( {\hat F} \right)}\right \rangle .$$

In addition, Eq. (9) should have been

$$ \hat \delta _{ba}^{jl}(\omega ) = \frac{{ig \hat{{\delta ^l}} (\omega ) - \hat F _{ba}^{jl}(\omega )}}{{(i\omega + i\Delta - \gamma )}} + \frac{{k\omega (\hat F _{th}^{jl}(\omega ) + F(\omega ))\bar \sigma _{ba}^{jl}}}{{m(v_t^2 - {\omega ^2} - i\gamma t\omega )(i\omega + i\Delta - \gamma )}}.$$

The Letter was corrected online on 23 March 2020.
