Title: On Tsirelson pairs of C*-algebras
Authors: Isaac Goldbring and Bradd Hart
Abstract summary: A Tsirelson pair of C*-algebras is a pair of C*-algebras for which the space of quantum strategies obtained by using states on the minimal tensor product of the pair coincide. We introduce the notion of a C*-algebra with the Tsirelson property (TP) and establish a number of closure properties for this class.

Abstract: We introduce the notion of a Tsirelson pair of C*-algebras, which is a pair of C*-algebras for which the space of quantum strategies obtained by using states on the minimal tensor product of the pair and the space of quantum strategies obtained by using states on the maximal tensor product of the pair coincide. We exhibit a number of examples of such pairs that are "nontrivial" in the sense that the minimal tensor product and the maximal tensor product of the pair are not isomorphic. For example, we prove that any pair containing a C*-algebra with Kirchberg's QWEP property is a Tsirelson pair. We then introduce the notion of a C*-algebra with the Tsirelson property (TP) and establish a number of closure properties for this class. We also show that the class of C*-algebras with the TP form an axiomatizable class (in the sense of model theory), but that this class admits no "effective" axiomatization.

Covariant decomposable maps on C*-algebras and quantum dynamics [0.0]
We provide a certain characterization of the operator sum representation of maps on $mathbbM_n (mathbbC)$. A connection to quantum dynamics is established by specifying sufficient and necessary conditions for covariance of D-divisible quantum evolution families.

Entanglement of Sections: The pushout of entangled and parameterized quantum information [0.0]
Recently Freedman & Hastings asked for a mathematical theory that would unify quantum entanglement/tensor-structure with parameterized/-structure. We make precise a form of the relevant pushout diagram in monoidal category theory. We show how this model category serves as categorical semantics for the linear-multiplicative fragment of Linear Homotopy Type Theory.

The Schmidt rank for the commuting operator framework [58.720142291102135]
The Schmidt rank is a measure for the entanglement dimension of a pure bipartite state. We generalize the Schmidt rank to the commuting operator framework. We analyze bipartite states and compute the Schmidt rank in several examples.

Quantum Current and Holographic Categorical Symmetry [62.07387569558919]
A quantum current is defined as symmetric operators that can transport symmetry charges over an arbitrary long distance. The condition for quantum currents to be superconducting is also specified, which corresponds to condensation of anyons in one higher dimension.

Quantum teleportation in the commuting operator framework [63.69764116066747]
We present unbiased teleportation schemes for relative commutants $N'cap M$ of a large class of finite-index inclusions $Nsubseteq M$ of tracial von Neumann algebras. We show that any tight teleportation scheme for $N$ necessarily arises from an orthonormal unitary Pimsner-Popa basis of $M_n(mathbbC)$ over $N'$.

Monogamy of entanglement between cones [68.8204255655161]
We show that monogamy is not only a feature of quantum theory, but that it characterizes the minimal tensor product of general pairs of convex cones. Our proof makes use of a new characterization of products of simplices up to affine equivalence.

We show that Lorentz cones are the only cones with a symmetric base for which a certain stronger version of the resilience property is satisfied. Our proof exploits the symmetries of the Lorentz cones and applies two constructions resembling protocols for entanglement distillation.
