TLDR
In this article, the authors discuss the connections between quantum and classical physics, information and its transfer, computation, and their significance for the formulation of physical theories, but also consider the origins and evolution of the information-processing entities, their complexity, and the manner in which they analyze their perceptions to form models of the Universe.Abstract:
This book has emerged from a meeting held during the week of May 29 to June 2, 1989, at St. John’s College in Santa Fe under the auspices of the Santa Fe Institute. The (approximately 40) official participants as well as equally numerous “groupies” were enticed to Santa Fe by the above “manifesto.” The book—like the “Complexity, Entropy and the Physics of Information” meeting explores not only the connections between quantum and classical physics, information and its transfer, computation, and their significance for the formulation of physical theories, but it also considers the origins and evolution of the information-processing entities, their complexity, and the manner in which they analyze their perceptions to form models of the Universe. As a result, the contributions can be divided into distinct sections only with some difficulty. Indeed, I regard this degree of overlapping as a measure of the success of the meeting. It signifies consensus about the important questions and on the anticipated answers: they presumably lie somewhere in the “border territory,” where information, physics, complexity, quantum, and computation all meet.read more

Filtrons and their associated ring computations
TL;DR: This work shows that filtrons may be generated in parallel by a multiprocessor ring net, and gives a method of calculating a whole filtron if its edge number and supporting FA are known, and of...

"Without in Any Way Disturbing the System": Illuminating the Issue of Quantum Nonlocality
TL;DR: In this article, the authors consider quantum phenomena and quantum mechanics from a nonrealist or, in terms adopted here, "reality-without-realism" (RWR) perspective.

TL;DR: This work has measured genome sequence complexity in the ancient phylum Cyanobacteria and applied three standard tests to detect if progressive evolution is passive or driven—the minimum, ancestor–descendant, and sub-clade tests.

Hypersensitivity to Perturbation: An Information-Theoretical Characterization of Classical and Quantum Chaos
Rüdiger Schack,Carlton M. Caves +1 more
TL;DR: In this article, a brief overview of hypersensitivity to perturbation in classical and quantum systems is given, together with a brief discussion of the general framework for hypersensitivity in quantum systems.

Spacetime Coarse Grainings and the Problem of Time in the Decoherent Histories Approach to Quantum Theory
TL;DR: In this article, the authors investigate the possibility of assigning consistent probabilities to sets of histories characterized by whether they enter a particular subspace of the Hilbert space of a closed system during a given time interval.
