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…

Demonstration of a switchable damping system to allow low-noise operation of high-Q low-mass suspension systems
Jan-Simon Hennig, Bryan W. Barr, Angus S. Bell +16
Low mass suspension systems with high-Q pendulum stages are used to enable quantum radiation pressure noise limited experiments. Utilising multiple pendulum stages with vertical bl…

Control of a velocity-sensitive audio-band quantum non-demolition interferometer
S. S. Leavey, S. L. Danilishin, A. Gläfke +16
The Sagnac speed meter interferometer topology can potentially provide enhanced sensitivity to gravitational waves in the audio-band compared to equivalent Michelson interferometer…
