Quantum noise of non-ideal Sagnac speed meter interferometer with asymmetries
S. L. Danilishin, C. Graef, S. S. Leavey +6
The speed meter concept has been identified as a technique that can potentially provide laser-interferometric measurements at a sensitivity level which surpasses the Standard Quant…
Observation of one-way Einstein-Podolsky-Rosen steering
Vitus Händchen, Tobias Eberle, Sebastian Steinlechner +4
The distinctive non-classical features of quantum physics were first discussed in the seminal paper by A. Einstein, B. Podolsky and N. Rosen (EPR) in 1935. In his immediate respons…
Continuous-wave non-classical light with GHz squeezing bandwidth
Stefan Ast, Aiko Samblowski, Moritz Mehmet +3
Squeezed states can be employed for entanglement-based continuous-variable quantum key distribution, where the secure key rate is proportional to the bandwidth of the squeezing. We…
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…
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…
High-efficiency frequency doubling of continuous-wave laser light
Stefan Ast, Ramon Moghadas Nia, Axel Schönbeck +6
We report on the observation of high efficiency frequency doubling of 1550 nm continuous-wave laser light in a nonlinear cavity containing a periodically poled potassium titanyl ph…
