  In the context of Matrix/light-cone gauge M-theory, we develop a new approach
for computing quantum entanglement between a probe gravitating in the vicinity
of a source mass and the source mass. We demonstrate that this entanglement is
related to the gravitational potential energy between the two objects. We then
show that the Von Neumann entropy is a function of two derivatives of the
gravitational potential. We conjecture a relation between the entropy and the
local Riemann tensor sampled by the probe, establishing a general scheme to
relate entropy to local geometric data. This relation connects the rate of
change, rotation, and twist of a small volume element at the probe's location
to the quantum entanglement of the probe with the source.
