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…
Engineering the Optical Spring via Intra-Cavity Optical-Parametric Amplification
Mikhail Korobko, Farid Ya. Khalili, Roman Schnabel
The 'optical spring' results from dynamical back-action and can be used to improve the sensitivity of cavity-enhanced gravitational-wave detectors. The effect occurs if an oscillat…
Quantum tomography enhanced through parametric amplification
E. Knyazev, K. Yu. Spasibko, M. V. Chekhova +1
Quantum tomography is the standard method of reconstructing the Wigner function of quantum states of light by means of balanced homodyne detection. The reconstruction quality stron…
Sub-SQL Sensitivity via Optical Rigidity in Advanced LIGO Interferometer with Optical Losses
F. Ya. Khalili, V. I. Lazebny, S. P. Vyatchanin
The ``optical springs'' regime of the signal-recycled configuration of laser interferometric gravitational-wave detectors is analyzed taking in account optical losses in the interf…
Reducing the mirrors coating noise in laser gravitational-wave antennae by means of double mirrors
F. Ya. Khalili
Recent researches show that the fluctuations of the dielectric mirrors coating thickness can introduce a substantial part of the future laser gravitational-wave antennae total nois…
