Squeezing for dispersive readout of NV magnetometer
A. M. Kozodaev, S. M. Drofa, P. G. Vilyuzhanina +9
Nitrogen vacancy centers in diamond have established themselves as good sensing element for various type of sensors. In particular magnetometers based on diamond impurities are qui…
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 , where is a numerical prefactor and is the mean number of photons interact…
Using non-Gaussian quantum states for detection of a given phase shift
V. L. Gorshenin, F. Ya. Khalili
Injecting a non-Gaussian (Fock or Shrödinger cat) quantum state into the dark port of a two-arm interferometer and a strong classical light into the bright one, it is possible, in…
A new double-pass type of the optical spring
F. Ya. Khalili
In detuned optical cavities, the radiation pressure force acting on the mirrors depends on their displacements. This is equivalent to the rigidity (the optical spring), inserted be…
Quantum noise cancellation in asymmetric speed meters with balanced homodyne readout
T Zhang, E Knyazev, S Steinlechner +17
Sagnac speed meter (SSM) topology is known as an alternative technique to reduce quantum back-action in gravitational-wave interferometers. However, any potential imbalance of the…
