Quantum Causal Histories and the Directed Graph Operator Framework
نویسنده
چکیده
A mathematical formalism called Quantum Causal Histories was recently invented as an attempt to describe causality within a quantum theory of gravity. Fundamental examples include quantum computers. We show there is a connection between this formalism and the directed graph operator framework from the theory of operator algebras.

A Unified Framework for Graph Algebras and Quantum Causal Histories
We present a mathematical framework that unifies the quantum causal history formalism from theoretical high energy physics and the directed graph operator framework from the theory of operator algebras. The approach involves completely positive maps and directed graphs and leads naturally to a new class of operator algebras.
متن کاملDecoherent histories on graphs
The consistent histories approach to quantum mechanics is traditionally based on linearly ordered sequences of events. We extend the histories formalism to sets of events whose causal ordering is described by directed acyclic graphs. The need for a global time is eliminated and our construction reflects the causal structure faithfully.
متن کاملQuantum causal histories
Quantum causal histories are defined to be causal sets with Hilbert spaces attached to each event and local unitary evolution operators. The reflexivity, antisymmetry, and transitivity properties of a causal set are preserved in the quantum history as conditions on the evolution operators. A quantum causal history in which transitivity holds can be treated as “directed” topological quantum fiel...
متن کاملImplementing causality in the spin foam quantum geometry
We analyse the classical and quantum geometry of the Barrett-Crane spin foam model for four dimensional quantum gravity, explaining why it has to be considering as a covariant realization of the projector operator onto physical quantum gravity states. We discuss how causality requirements can be consistently implemented in this framework, and construct causal transiton amplitudes between quantu...
متن کاملScalar Field Theory on a Causal Set in Histories Form
We recast into histories-based form a quantum field theory defined earlier in operator language for a free scalar field on a background causal set. The resulting decoherence functional resembles that of the continuum theory but the counterpart of the d’Alembertian operator is nonlocal and a generalized inverse of the discrete retarded Green function. We comment on the significance of this and w...
