Strong Einstein-Podolsky-Rosen steering with unconditional entangled states
Sebastian Steinlechner, Jöran Bauchrowitz, Tobias Eberle +1
In 1935 Schrödinger introduced the terms entanglement and steering in the context of the famous gedanken experiment discussed by Einstein, Podolsky, and Rosen (EPR). Here, we repor…
Status of the GEO 600 squeezed-light laser
Alexander Khalaidovski, Henning Vahlbruch, Nico Lastzka +5
In the course of the high-frequency upgrade of GEO 600, its optical configuration was extended by a squeezed-light laser [1]. Recently, a non-classically enhanced measurement sensi…
Squeezed light at 1550 nm with a quantum noise reduction of 12.3 dB
Moritz Mehmet, Stefan Ast, Tobias Eberle +3
Continuous-wave squeezed states of light at the wavelength of 1550 nm have recently been demonstrated, but so far the obtained factors of noise suppression still lag behind today's…
Gaussian Entanglement for Quantum Key Distribution from a Single-Mode Squeezing Source
Tobias Eberle, Vitus Händchen, Jörg Duhme +4
We report the suitability of an Einstein-Podolsky-Rosen (EPR) entanglement source for gaussian continuous-variable quantum key distribution at 1550 nm. Our source is based on a sin…
The critical Kerr non-linear optical cavity in the presence of internal loss and driving noise
Andre Thuering, Roman Schnabel
We theoretically analyze the noise transformation of a high power continuouswave light field that is reflected off a critical Kerr non-linear cavity (KNLC). Our investigations are…
Long-term stable squeezed vacuum state of light for gravitational wave detectors
Alexander Khalaidovski, Henning Vahlbruch, Nico Lastzka +4
Currently, the German/British gravitational wave detector GEO600 is being upgraded in course of the GEO-HF program. One part of this upgrade consists of the integration of a squeez…
