Nonlocality without entanglement: Quantum theory and beyond
Some Sankar Bhattacharya, Sutapa Saha, Tamal Guha, Manik Banik
Abstract
The authors show that the indistinguishability of state preparation is not specific to quantum theory, but a generic property of a larger class of generalized probability theories. It is also shown that this feature in quantum theory is quantitatively limited compared to other generalized theories, attributing to one of the topological structures of Hilbert space quantum mechanics.
