Blind steering in no-signalling theories

Quantum Physics 2021-05-21 v4

Abstract

Steering is a physical phenomenon which is not restricted to quantum theory, it is also present in more general, no-signalling theories. Here, we study steering from the point of view of no-signalling theories. First, we show that quantum steering involves a collection of different aspects, which need to be separated when considering steering in no-signalling theories. By deconstructing quantum steering, we learn more about the nature of the steering phenomenon itself. Second, we introduce a new concept, that we call "blind steering", which can be seen as the most basic form of steering, present both in quantum mechanics and no-signalling theories.
