چکیده

We consider a number of proposals for the entropy of sets of classical coarse-grained histories based on the procedures of Jaynes, and we prove a series of inequalities relating these measures. We then examine these as a function of the coarse-graining for various classical systems, and show explicitly that the entropy is minimized by the finest-grained description of a set of histories. We propose an extension of the second law of thermodynamics to the entropy of histories. We briefly discuss the implications for decoherent or consistent history formulations of quantum mechanics.

Quantum Information: What Is It All About?

This paper answers Bell’s question: What does quantum information refer to? It is about quantum properties represented by subspaces of the quantum Hilbert space, or their projectors, to which standard (Kolmogorov) probabilities can be assigned by using a projective decomposition of the identity (PDI or framework) as a quantum sample space. The single framework rule of consistent histories preve...

Preferred Observables, Predictability, Classicality, and the Environment-induced Decoherence

Selection of the preferred classical set of states in the process of decoherence – so important for cosmological considerations – is discussed with an emphasis on the role of information loss and entropy. Persistence of correlations between the observables of two systems (for instance, a record and a state of a system evolved from the initial conditions described by that record) in the presence...

Consistent-histories Description of a World with Increasing Entropy

1. Attempt at a self-contained quantum description The consistent-histories program 1,2,3 represents a more concerted effort than previous attempts to overcome what some workers regard as the main defect of the Copenhagen interpretation: the need to invoke the existence of a classical world as a precondition to the meaningful interpretation of quantum mechanics. Hence, just as for any other att...

Time’s Arrow from the Multiverse Point of View

In this paper I suggest a possible explanation for the asymmetry of time. In the models that I study, the dynamical laws and the boundary conditions are completely symmetric, but the behaviour of time is not. The underlying mechanism is a spontaneously broken symmetry on the micro-level which is closely related to the idea of multiple histories in quantum mechanics. The situations that I will d...

Decoherence and linear entropy increase in the quantum baker's map.

We show that the coarse-grained quantum baker's map exhibits a linear entropy increase at an asymptotic rate given by the Kolmogorov-Sinai entropy of the classical chaotic baker's map. The starting point of our analysis is a symbolic representation of the map on a string of N qubits, i.e., an N-bit register of a quantum computer. To coarse grain the quantum evolution, we make use of the decoher...
