“Time” replaced by quantum correlations

  • William K. Wootters
The Loyola Conference Papers Presented at the Second New Orleans Conference on Quantum Theory and Gravitation, Loyola University, New Orleans, May, 1983


Abstract coordinate time is not observable, but “clock time” is observable, Therefore, any statement about temporal evolution can be replaced, without loss of observational content, by a statement about correlations between a clock and another physical system. We show that information about such correlations can be represented just as well in a single “timeless” quantum state as in a whole history of states. It is therefore not necessary to include “time” as a basic element in the description of the world.
