Multipartite quantum and classical correlations in symmetric n-qubit mixed states
Gian Luca Giorgi, Steve Campbell
We discuss how to calculate genuine multipartite quantum and classical correlations in symmetric, spatially invariant, mixed -qubit density matrices. We show that the existence…
Characterization and properties of weakly optimal entanglement witnesses
Bang-Hai Wang, Hai-Ru Xu, Steve Campbell +1
We present an analysis of the properties and characteristics of weakly optimal entanglement witnesses, that is witnesses whose expectation value vanishes on at least one product ve…
Quenching small quantum gases: Genesis of the orthogonality catastrophe
Steve Campbell, Miguel Ángel García-March, Thomás Fogarty +1
We study the dynamics of two strongly interacting bosons with an additional impurity atom trapped in a harmonic potential. Using exact numerical diagonalization we are able to full…
Correlation approach to work extraction from finite quantum systems
Gian Luca Giorgi, Steve Campbell
Reversible work extraction from identical quantum systems via collective operations was shown to be possible even without producing entanglement among the sub-parts. Here, we show…
