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…
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…
