Evidence of Two-Source King Plot Nonlinearity in Spectroscopic Search for New Boson
Joonseok Hur, Diana P. L. Aude Craik, Ian Counts +12
Optical precision spectroscopy of isotope shifts can be used to test for new forces beyond the Standard Model, and to determine basic properties of atomic nuclei. We measure isotop…
Overcoming inefficient detection in sub-shot-noise absorption measurement and imaging
E. Knyazev, F. Ya. Khalili, M. V. Chekhova
Photon-number squeezing and correlations enable measurement of absorption with an accuracy exceeding that of the shot-noise limit. However, sub-shot noise imaging and sensing based…
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…
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…
A new type of quantum speed meter interferometer: measuring speed to search for intermediate mass black holes
Stefan L. Danilishin, Eugene Knyazev, Nikita V. Voronchev +5
The recent discovery of gravitational waves (GW) by LIGO has impressively launched the novel field of gravitational astronomy and it allowed us to glimpse at exciting objects we co…
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…
