Bimodal non-Gaussian photonic states from a single quantum emitter in a waveguide
Thomas Copie, Ofer Firstenberg, G. P. Teja +2
We investigate the generation of deterministic and heralded non-Gaussian states of light, using a single two-level system coupled to a chiral waveguide. We study the case of a sing…
Deterministic nonlinear bunching of bosons
Kingshuk Adhikary, Darren W. Moore, Radim Filip
The ability of bosonic energy quanta to bunch together in an energy-conserving interaction is a fundamental feature of quantum harmonic oscillators. Linear systems together with me…
Entanglement with a mode observable via a tunable interaction with a qubit
MaÅgorzata StrzaÅka, Radim Filip, Katarzyna Roszak
We study the possibility of detection of ``spin-boson'' entanglement by qubit only measurements. Such entanglement is impossible to detect by previously proposed schemes that invol…
Nonclassical nullifiers for quantum hypergraph states
Abhijith Ravikumar, Darren W. Moore, Radim Filip
Quantum hypergraph states form a generalisation of the graph state formalism that goes beyond the pairwise (dyadic) interactions imposed by remaining inside the Gaussian approximat…
Broadcasting quantum nonlinearity in hybrid systems
Alisa D. Manukhova, Andrey A. Rakhubovsky, Radim Filip
Linear oscillators contribute to most branches of contemporary quantum science. They have already successfully served as quantum sensors and memories, found applications in quantum…
Maximum precision charging of multi-qubit quantum batteries
Davide Rinaldi, Radim Filip, Dario Gerace +1
Precision, robustness, and efficiency are crucial aspects in the design of quantum technologies. Here, we show how genuine quantum features, together with non-Gaussianity, can be t…
