Communication of Partial Ignorance with Qubits
November 5th, 2019 TEIKO HEINOSAARI University of Turku

In this talk, I will introduce a class of communication tests where the task is to communicate partial ignorance by means of a physical system. I will then present a full characterization of the implementations of these tests in the qubit case and partial results for qudits. A peculiar observation is that two physical systems with the same operational dimensions may differ with respect to implementations of these tasks, as is shown to be the case for the qubit and rebit. Finally, I will discuss the natural question whether some of the communication tests are more difficult than others.
