Interferometric detection of continuous-variable entanglement using two states
Elena Callus, Martin Gärttner, Tobias Haas
The efficient witnessing and certification of entanglement is necessitated by its ubiquitous use in various aspects of quantum technologies. In the case of continuous-variable bipa…

Purcell-Enhanced, Directional Light-Matter Interaction in a Waveguide-Coupled Nanocavity
Nicholas J. Martin, Dominic Hallett, Mateusz Duda +9
We demonstrate electrically tunable, spin-dependent, directional coupling of single photons by embedding quantum dots (QDs) in a waveguide-coupled nanocavity. The directional behav…

Cumulative generation of maximal entanglement between spectrally distinct qubits using squeezed light
Elena Callus, Pieter Kok
We demonstrate how to create maximal entanglement between two qubits that are encoded in two spectrally distinct solid-state quantum emitters embedded in a waveguide interferometer…
