Cooper pair polaritons in cold fermionic atoms within a cavity
Amaury Dodel, Alexander Pikovski, Igor Ermakov +4
We formulate a Bardeen-Cooper-Schriffer (BCS) theory of quasiparticles in a degenerate Fermi gas strongly coupled to photons in a optical cavity. The elementary photonic excitation…
Solitonic fixed point attractors in the complex Ginzburg-Landau equation for associative memories
A. N. Pyrkov, T. Byrnes, V. V. Cherny
It was recently shown [V.V. Cherny, T. Byrnes, A.N. Pyrkov, \textit{Adv. Quantum Technol.} \textbf{2019} \textit{2}, 1800087] that the nonlinear Schrodinger equation with a simplif…
Super-quantum discord in ferromagnetic and antiferromagnetic materials
A. V. Fedorova, T. Byrnes, A. N. Pyrkov
Super-quantum discord is an extension of the quantum discord concept where weak measurements are made instead of projective measurements. We study the temperature behavior of the s…
Error suppression in adiabatic quantum computing with qubit ensembles
Naeimeh Mohseni, Marek Narozniak, Alexey N. Pyrkov +3
Incorporating protection against quantum errors into adiabatic quantum computing (AQC) is an important task due to the inevitable presence of decoherence. Here we investigate an er…
Characterizing coherence with quantum observables
Suman Mandal, Marek Narozniak, Chandrashekar Radhakrishnan +3
We introduce a procedure based on quantum expectation values of measurement observables to characterize quantum coherence. Our measure allows one to quantify coherence without havi…
A multipartite generalization of quantum discord
Chandrashekar Radhakrishnan, Mathieu Lauriere, Tim Byrnes
A generalization of quantum discord to multipartite systems is proposed. A key feature of our formulation is its consistency with the conventional definition of discord in bipartit…
