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…
Continuous-wave squeezed states of light via 'up-down' self-phase modulation
Amrit Pal Singh, Stefan Ast, Moritz Mehmet +2
Continuous-wave (cw) squeezed states of light have applications in sensing, metrology and secure communication. In recent decades their efficient generation has been based on param…
Gaussian entanglement distribution with gigahertz bandwidth
Stefan Ast, Melanie Ast, Moritz Mehmet +1
The distribution of entanglement with Gaussian statistic can be used to generate a mathematically-proven secure key for quantum cryptography. The distributed secret key rate is lim…
High-bandwidth squeezed light at 1550 nm from a compact monolithic PPKTP cavity
Stefan Ast, Moritz Mehmet, Roman Schnabel
We report the generation of squeezed vacuum states of light at 1550 nm with a broadband quantum noise reduction of up to 4.8 dB ranging from 5 MHz to 1.2 GHz sideband frequency. We…
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…
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…
