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…
Sub-Planck structure quantification in non-Gaussian probability densities
Darren W. Moore, Vojtěch Švarc, Kratveer Singh +5
Sub-Planck structures in non-Gaussian probability densities of phase space variables are pervasive in bosonic quantum systems. They are almost universally present if the bosonic sy…
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…
Coherence of quantum non-Gaussian states via nonlinear absorption of quanta
Kingshuk Adhikary, Darren W. Moore, Radim Filip
The linear and phase insensitive absorption of a single quanta via coherent interactions with a saturable system, even a single ground state qubit, is sufficient to deterministical…
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…
Entanglement growth via splitting of a few thermal quanta
Pradip Laha, Darren W. Moore, Radim Filip
Quanta splitting is an essential generator of Gaussian entanglement, exemplified by Einstein-Podolsky-Rosen states and apparently the most commonly occurring form of entanglement.…
Thermally induced entanglement of atomic oscillators
Pradip Laha, Lukáš Slodička, Darren W. Moore +1
Laser cooled ions trapped in a linear Paul trap are long-standing ideal candidates for realizing quantum simulation, especially of many-body systems. The properties that contribute…
Bayesian optimization of non-classical optomechanical correlations
Alexander Pitchford, Andrey A. Rakhubovsky, Rick Mukherjee +5
Nonclassical correlations provide a resource for many applications in quantum technology as well as providing strong evidence that a system is indeed operating in the quantum regim…
Detecting nonclassical correlations in levitated cavity optomechanics
Andrey A. Rakhubovsky, Darren W. Moore, Uroš Delić +3
Nonclassical optomechanical correlations enable optical control of mechanical motion beyond the limitations of classical driving. Here we investigate the feasibility of using pulse…
Quantum Hypergraph States in Continuous Variables
Darren W. Moore
The measurement based, or one-way, model of quantum computation for continuous variables uses a highly entangled state called a cluster state to accomplish the task of computing. C…
Estimation of squeezing in a nonlinear quadrature of a mechanical oscillator
Darren W. Moore, Andrey A. Rakhubovsky, Radim Filip
Processing quantum information on continuous variables requires a highly nonlinear element in order to attain universality. Noise reduction in processing such quantum information i…
Nonclassical states of levitated macroscopic objects beyond the ground state
Andrey A. Rakhubovsky, Darren W. Moore, Radim Filip
The preparation of nonclassical states of mechanical motion conclusively proves that control over such motion has reached the quantum level. We investigate ways to achieve nonclass…
Unconditional measurement-based quantum computation with optomechanical continuous variables
Oussama Houhou, Darren W. Moore, Sougato Bose +1
Universal quantum computation encoded over continuous variables can be achieved via Gaussian measurements acting on entangled non-Gaussian states. However, due to the weakness of a…
Unconditional preparation of nonclassical states via linear-and-quadratic optomechanics
Matteo Brunelli, Oussama Houhou, Darren W. Moore +3
Reservoir engineering enables the robust preparation of pure quantum states in noisy environments. We show how a new family of quantum states of a mechanical oscillator can be stab…
Arbitrary multimode Gaussian operations on mechanical cluster states
Darren W. Moore, Oussama Houhou, Alessandro Ferraro
We consider opto- and electro-mechanical quantum systems composed of a driven cavity mode interacting with a set of mechanical resonators. It has been proposed that the latter can…

Darren W. Moore, Tommaso Tufarelli, Mauro Paternostro +1
We introduce a scheme to reconstruct an arbitrary quantum state of a mechanical oscillator network. We assume that a single element of the network is coupled to a cavity field via…
