Spekkens' Toy Model, Finite Field Quantum Mechanics, and the Role of Linearity
Lay Nam Chang, Djordje Minic, Tatsu Takeuchi
We map Spekkens' toy model to a quantum mechanics defined over the finite field . This allows us to define arbitrary linear combinations of the epistemic states in th…
Observable Effects of Quantum Gravity
Lay Nam Chang, Djordje Minic, Chen Sun +1
We discuss the generic phenomenology of quantum gravity and, in particular, argue that the observable effects of quantum gravity, associated with new, extended, non-local, non-part…
On the Physics of the Minimal Length: The Question of Gauge Invariance
Lay Nam Chang, Djordje Minic, Ahmed Roman +2
In this note we discuss the question of gauge invariance in the presence of a minimal length. This contribution is prepared for the celebration of the 60th anniversary of the Yang-…
Quantum Systems based upon Galois Fields: from Sub-quantum to Super-quantum Correlations
Lay Nam Chang, Zachary Lewis, Djordje Minic +1
In this talk we describe our recent work on discrete quantum theory based on Galois fields. In particular, we discuss how discrete quantum theory sheds new light on the foundations…
Quantum F_un: the q=1 Limit of Galois Field Quantum Mechanics, Projective Geometry, and the Field with One Element
Lay Nam Chang, Zachary Lewis, Djordje Minic +1
We argue that the q=1 limit of Galois Field Quantum Mechanics, which was constructed on a vector space over the Galois Field F_q=GF(q), corresponds to its `classical limit,' where…
Is Quantum Gravity a Super-Quantum Theory?
Lay Nam Chang, Zachary Lewis, Djordje Minic +1
We argue that quantum gravity should be a super-quantum theory, that is, a theory whose non-local correlations are stronger than those of canonical quantum theory. As a super-quant…
