When does a physical system compute?
Computing is a high-level process of a physical system. Recent interest in non-standard computing systems, including quantum and biological computers, has brought this physical basis of computing to the forefront. There has been, however, no consensus on how to tell if a given physical system is acting as a computer or not; leading to confusion over novel computational devices, and even claims ...

متن کاملConcrete Digital Computation: What Does it Take for a Physical System to Compute?
This paper deals with the question: what are the key requirements for a physical system to perform digital computation? Time and again cognitive scientists are quick to employ the notion of computation simpliciter when asserting basically that cognitive activities are computational. They employ this notion as if there was or is a consensus on just what it takes for a physical system to perform ...
متن کاملWhen Can Solitons Compute?
We explore the possibility of using soliton interactions in a one-dimensional bulk medium as a basis for a new kind of computer. Such a structure is “gateless” – all computations are determined by an input stream of solitons. Intuitively, the key requirement for accomplishing this is that soliton collisions be nonoblivious; that is, solitons should transfer state information during collisions. ...
