Entanglement robustness against particle loss in multiqubit systems
Antoine Neven, John Martin, Thierry Bastin
When some of the parties of a multipartite entangled pure state are lost, the question arises whether the residual mixed state is also entangled, in which case the initial entangle…
The quantum separability problem is a simultaneous hollowisation matrix analysis problem
Antoine Neven, Thierry Bastin
We use the generalized concurrence approach to investigate the general multipartite separability problem. By extending the preconcurrence matrix formalism to arbitrary multipartite…
Coherent quantum dynamics launched by incoherent relaxation in a quantum circuit simulator of a light-harvesting complex
A. W. Chin, E. Mangaud, O. Atabek +1
Engineering and harnessing coherent excitonic transport in organic nanostructures has recently been suggested as a promising way towards improving man-made light harvesting materia…
Analytical results for the quantum non-Markovianity of spin ensembles undergoing pure dephasing dynamics
Rémy Dubertrand, Alexandre Cesa, John Martin
We study analytically the non-Markovianity of a spin ensemble, with arbitrary number of spins and spin quantum number, undergoing a pure dephasing dynamics. The system is considere…
