No-signaling values of quantum games--an operator algebra perspective
Roy Araiza, Marius Junge, Carlos Palazuelos
The aim of this work is to study two-prover quantum games (i.e., games with quantum inputs and outputs) from an operator-algebraic and operator-space point of view. We characterize…

The Hidden Nature of Non-Markovianity
Jihong Cai, Advith Govindarajan, Marius Junge
The theory of open quantum systems served as a tool to prepare entanglement at the beginning stage of quantum technology and more recently provides an important tool for state prep…

Transportation cost and contraction coefficient for channels on von Neumann algebras
Roy Araiza, Marius Junge, Peixue Wu
We present a noncommutative optimal transport framework for quantum channels acting on von Neumann algebras. Our central object is the Lipschitz cost measure, a transportation-insp…
