Overcoming the SQL in gravitational wave detectors using spin systems with negative effective mass
Farid Khalili, Eugene S. Polzik
Quantum back action (QBA) of a measurement limits the precision of observation of the motion of a free mass. This profound effect dabbed the "Heisenberg microscope" in the early da…
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…
Speedmeter scheme for gravitational-wave detectors based on EPR quantum entanglement
E. Knyazev, S. Danilishin, S. Hild +1
We propose a new implementation of a quantum speed meter QND measurement scheme. It employs two independent optical readouts of the interferometer test masses, featuring strongly d…
