Entanglement with a mode observable via a tunable interaction with a qubit
Małgorzata Strzałka, 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…
Nonlinear stochastic and quantum motion from Coulomb forces
Luca Ornigotti, Darren W. Moore, Radim Filip
Controllable nonlinear quantum interactions are a much sought after target for modern quantum technologies. They are typically difficult and costly to engineer for bespoke purposes…
Witnessing quantum non-Gaussianity from intensity moments
Éva Rácz, László Ruppert, Radim Filip
Direct measurement of quantum non-Gaussianity requires some variant of a discrete photon-resolving detection, which is feasible only for low mean photon numbers. For a large mean p…
Certifying non-classicality and non-Gaussianity through optical parametric amplification
Mahmoud Kalash, Marcello H. M. Passos, Éva Rácz +3
Non-Gaussian states of light are essential for numerous quantum information protocols; thus, certifying non-Gaussianity is crucial. Full quantum state tomography, commonly used for…
Nonlinear Phase Gates as Airy Transforms of the Wigner Function
Darren W. Moore, Radim Filip
Low-order nonlinear phase gates allow the construction of versatile higher-order nonlinearities for bosonic systems and grant access to continuous variable quantum simulations of m…
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…
