Gaining confidence on the correct realization of arbitrary quantum computations
Jose Carrasco, Marc Langer, Antoine Neven +1
We present verification protocols to gain confidence in the correct performance of the realization of an arbitrary universal quantum computation. The derivation of the protocols is…

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…
