I take it that physics provides our scientific understanding of that world at the most
fundamental level. However, its theories are perpetually provisional and the more or less …

Entropy is a basic physical quantity that led to various, and sometimes apparently con icting
interpretations. It has been successively assimilated to di erent concepts such as disorder …

Landauer's principle is the loosely formulated notion that the erasure of n bits of information
must always incur a cost of klnn in thermodynamic entropy. It can be formulated as a precise …

Quantum theory predicts experimental results brilliantly but simultaneously raises difficult
conceptual issues. Paradoxes such as Schrödinger's cat, the EPR paradox, or the …

In a recent paper [Stud. Hist. Philos. Mod. Phys. 36, 355 (2005)] it is argued that to properly
understand the thermodynamics of Landauer's principle it is necessary to extend the …

Landauer erasure seems to provide a powerful link between thermodynamics and
information processing (logical computation). The only logical operations that require a …

While quantum information theory is one of the most lively, up-and-coming new areas of
research in physics, its central concerns have long been familiar. They are simply those that …

The paper analyzes the probability distribution of the occupancy numbers and the entropy of
a system at the equilibrium composed by an arbitrary number of non-interacting bosons. The …

A number of researchers today make an appeal to quantum physics when trying to develop
a satisfactory account of the mind, an appeal still felt to be controversial by many. Often …

If the density matrix is treated as an objective description of individual systems, it may
become possible to attribute the same objective significance to statistical mechanical …
