Reference frames which separately store non-commuting conserved quantities
Sandu Popescu, Ana Belén Sainz, Anthony J. Short +1
Even in the presence of conservation laws, one can perform arbitrary transformations on a system if given access to a suitable reference frame, since conserved quantities may be ex…
How to quantify a dynamical quantum resource
Gilad Gour, Andreas Winter
We show that the generalization of the relative entropy of a resource from states to channels is not unique, and there are at least six such generalizations. We then show that two…
LOCC protocols with bounded width per round optimize convex functions
Debbie Leung, Andreas Winter, Nengkun Yu
We start with the task of discriminating finitely many multipartite quantum states using LOCC protocols, with the goal to optimize the probability of correctly identifying the stat…
Resource theories of quantum channels and the universal role of resource erasure
Zi-Wen Liu, Andreas Winter
We initiate the systematic study of resource theories of quantum channels, i.e. of the dynamics that quantum systems undergo by completely positive maps, in abstracto: Resources ar…
Indistinguishability-enabled coherence for quantum metrology
Alessia Castellini, Rosario Lo Franco, Ludovico Lami +3
Quantum coherence plays a fundamental and operational role in different areas of physics. A resource theory has been developed to characterize the coherence of distinguishable part…
Entanglement-Assisted Quantum Data Compression
Zahra Baghali Khanian, Andreas Winter
Ask how the quantum compression of ensembles of pure states is affected by the availability of entanglement, and in settings where the encoder has access to side information. We fi…
