Maximal Coherence and the Resource Theory of Purity
Alexander Streltsov, Hermann Kampermann, Sabine Wölk +2
The resource theory of quantum coherence studies the off-diagonal elements of a density matrix in a distinguished basis, whereas the resource theory of purity studies all deviation…
Resolution-enhanced entanglement detection
Manuel Gessner, Luca Pezzè, Augusto Smerzi
We formulate a general family of entanglement criteria for multipartite systems. Fisher information criteria compare the sensitivity to unitary rotations with the variances of suit…
Local probe of single phonon dynamics in warm ion crystals
Ahmed Abdelrahman, Omid Khosravani, Manuel Gessner +8
The detailed characterization of non-trivial coherence properties of composite quantum systems of increasing size is an indispensable prerequisite for scalable quantum computation,…
Efficient entanglement criteria for discrete, continuous, and hybrid variables
Manuel Gessner, Luca Pezzè, Augusto Smerzi
We provide a method to construct entanglement criteria for arbitrary multipartite systems of discrete or continuous variables and hybrid combinations of both. While any set of loca…
On the reduced dynamics of a subset of interacting bosonic particles
Manuel Gessner, Andreas Buchleitner
The quantum dynamics of a subset of interacting bosons in a subspace of fixed particle number is described in terms of symmetrized many-particle states. A suitable partial trace op…
The local detection method: Dynamical detection of quantum discord with local operations
Manuel Gessner, Heinz-Peter Breuer, Andreas Buchleitner
Quantum discord in a bipartite system can be dynamically revealed and quantified through purely local operations on one of the two subsystems. To achieve this, the local detection…
