Engineering the Optical Spring via Intra-Cavity Optical-Parametric Amplification
Mikhail Korobko, Farid Ya. Khalili, Roman Schnabel
The 'optical spring' results from dynamical back-action and can be used to improve the sensitivity of cavity-enhanced gravitational-wave detectors. The effect occurs if an oscillat…
Continuous-Variable Protocol for Oblivious Transfer in the Noisy-Storage Model
Fabian Furrer, Tobias Gehring, Christian Schaffner +3
Cryptographic protocols are the backbone of our information society. This includes two-party protocols which offer protection against distrustful players. Such protocols can be bui…
Negative Wigner function at telecommunication wavelength from homodyne detection
Christoph Baune, Jaromir Fiurasek, Roman Schnabel
Quantum states of light having a Wigner function with negative values represent a key resource in quantum communication and quantum information processing. Here, we present the gen…
