  We investigate the effects of quantum entanglement between our horizon patch
and others due to the tracing out of long wavelength modes in the wavefunction
of the Universe as defined on a particular model of the landscape. In this, the
first of two papers devoted to this topic, we find that the SUSY breaking scale
is bounded both above {\em and} below: $10^{-10} M_{\rm P}\leq M_{\rm SUSY}\leq
10^{-8} M_{\rm P}$ for $GUT$ scale inflation. The lower bound is at least five
orders of magnitude larger than the expected value of this parameter and can be
tested by LHC physics.
