Query: Reducing Spacetime to Binary Information   We present a new description of discrete space-time in 1+1 dimensions in
terms of a set of elementary geometrical units that represent its independent
classical degrees of freedom. This is achieved by means of a binary encoding
that is ergodic in the class of space-time manifolds respecting coordinate
invariance of general relativity. Space-time fluctuations can be represented in
a classical lattice gas model whose Boltzmann weights are constructed with the
discretized form of the Einstein-Hilbert action. Within this framework, it is
possible to compute basic quantities such as the Ricci curvature tensor and the
Einstein equations, and to evaluate the path integral of discrete gravity. The
description as a lattice gas model also provides a novel way of quantization
and, at the same time, to quantum simulation of fluctuating space-time.
