Classical Physics and the Church-Turing Thesis
Would physical laws permit the construction of computing machines that are capable of solving some problems much faster than the standard computational model? Recent evidence sugge...

The physical Church-Turing thesis and the principles of quantum theory
Abstract. Notoriously, quantum computation shatters complexity theory, but is innocuous to computability theory [17]. Yet several works have shown how quantum theory as it stands c...

From Logic to Physics: How the Meaning of Computation Changed over Time
The intuition guiding the de…nition of computation has shifted over time, a process that is re‡ected in the changing formulations of the Church-Turing thesis. The theory of co...

If a tree casts a shadow is it telling the time?
Physical processes are computations only when we use them to externalize thought. Entities provide nature with a way to preserve structure over time. We think in terms of entities ...

Quantum complexity theory
In this paper we study quantum computation from a complexity theoretic viewpoint. Our first result is the existence of an efficient universal quantum Turing machine in Deutsch’s...
