Revealing entanglement through local features of phase-space distributions

Elena Callus, Martin Gärttner, Tobias Haas

We formulate an infinite hierarchy of continuous-variable separability criteria in terms of quasiprobability distributions and their derivatives evaluated at individual points in p…

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…

Spin-augmented observables for efficient photonic quantum error correction

Elena Callus, Pieter Kok

We demonstrate that the spin state of solid-state emitters inside micropillar cavities can serve as measure qubits in syndrome measurements. The photons, acting as data qubits, int…

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…
