Quantum Metrology for Gravitational Wave Astronomy

Roman Schnabel, Nergis Mavalvala, David E. McClelland +1

Einstein's General Theory of Relativity predicts that accelerating mass distributions produce gravitational radiation, analogous to electromagnetic radiation from accelerating char…

Detection of 15 dB Squeezed States of Light and their Application for the Absolute Calibration of Photoelectric Quantum Efficiency

Henning Vahlbruch, Moritz Mehmet, Karsten Danzmann +1

Squeezed states of light belong to the most prominent nonclassical resources. They have compelling applications in metrology, which has been demonstrated by their routine exploitat…

GHZ protocols enhance frequency metrology despite spontaneous decay

Timm Kielinski, Piet O. Schmidt, Klemens Hammerer

The use of correlated states and measurements promises improvements in the accuracy of frequency metrology and the stability of atomic clocks. However, developing strategies robust…

Particle detectors under chronological hazard

Ana Alonso-Serrano, Erickson Tjoa, Luis J. Garay +1

We analyze how the presence of closed timelike curves (CTCs) characterizing a time machine can be discerned by placing a local particle detector in a region of spacetime which is c…

Quantum enhanced balanced heterodyne readout for differential interferometry

Daniel W. Gould, Vaishali B. Adya, Sheon S. Y. Chua +8

Conventional heterodyne readout schemes are now under reconsideration due to the realization of techniques to evade its inherent 3 dB signal-to-noise penalty. The application of hi…
