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…
Sandwich theorems and capacity bounds for non-commutative graphs
Gareth Boreland, Ivan G. Todorov, Andreas Winter
We define non-commutative versions of the vertex packing polytope, the theta convex body and the fractional vertex packing polytope of a graph, and establish a quantum version of t…
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…
Stochastic thermodynamics with arbitrary interventions
Philipp Strasberg, Andreas Winter
We extend the theory of stochastic thermodynamics in three directions: (i) instead of a continuously monitored system we consider measurements only at an arbitrary set of discrete…
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…
