Standard Quantum Limit for Probing Mechanical Energy Quantization
Haixing Miao, Stefan Danilishin, Thomas Corbitt +1
We derive a standard quantum limit for probing mechanical energy quantization in a class of systems with mechanical modes parametrically coupled to external degrees of freedom. To…
Quantum state preparation and macroscopic entanglement in gravitational-wave detectors
Helge Mueller-Ebhardt, Henning Rehbein, Chao Li +5
Long-baseline laser-interferometer gravitational-wave detectors are operating at a factor of 10 (in amplitude) above the standard quantum limit (SQL) within a broad frequency band.…
Creation of a quantum oscillator by classical control
Stefan Danilishin, Helge Müller-Ebhardt, Henning Rehbein +7
As a pure quantum state is being approached via linear feedback, and the occupation number approaches and eventually goes below unity, optimal control becomes crucial. We obtain th…
Quantum engineering of squeezed states for quantum communication and metrology
Henning Vahlbruch, Simon Chelkowski, Karsten Danzmann +1
We report the experimental realization of squeezed quantum states of light, tailored for new applications in quantum communication and metrology. Squeezed states in a broad Fourier…
On the distillation and purification of phase-diffused squeezed states
B. Hage, A. Franzen, J. DiGuglielmo +3
Recently it was discovered that non-Gaussian decoherence processes, such as phase-diffusion, can be counteracted by purification and distillation protocols that are solely built on…
Detuned Twin-Signal-Recycling for ultra-high precision interferometers
Andre Thuering, Roman Schnabel, Harald Lueck +1
We propose a new interferometer technique for high precision phase measurements such as those in gravitational wave detection. The technique utilizes a pair of optically coupled re…
