Ab-initio Quantum Enhanced Optical Phase Estimation Using Real-time Feedback Control
Adriano A. Berni, Tobias Gehring, Bo M. Nielsen +3
Optical phase estimation is a vital measurement primitive that is used to perform accurate measurements of various physical quantities like length, velocity and displacements. The…
Implementation of Continuous-Variable Quantum Key Distribution with Composable and One-Sided-Device-Independent Security Against Coherent Attacks
Tobias Gehring, Vitus Händchen, Jörg Duhme +5
Secret communication over public channels is one of the central pillars of a modern information society. Using quantum key distribution this is achieved without relying on the hard…
Experimental entanglement distribution by separable states
Christina E. Vollmer, Daniela Schulze, Tobias Eberle +3
The distribution of entanglement between macroscopically separated parties represents a crucial protocol for future quantum information networks. Surprisingly, it has been theoreti…
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…
Strong Einstein-Podolsky-Rosen entanglement from a single squeezed light source
Tobias Eberle, Vitus Händchen, Jörg Duhme +3
Einstein-Podolsky-Rosen (EPR) entanglement is a criterion that is more demanding than just certifying entanglement. We theoretically and experimentally analyze the low resource gen…
Quantum Enhancement of the Zero-Area Sagnac Interferometer Topology for Gravitational Wave Detection
Tobias Eberle, Sebastian Steinlechner, Jöran Bauchrowitz +5
Only a few years ago, it was realized that the zero-area Sagnac interferometer topology is able to perform quantum nondemolition measurements of position changes of a mechanical os…
