- Abstract: Entanglement distribution will form the backbone of many future distributed
quantum technologies, especially the quantum internet. The act of purifying
multiple noisy entangled states into a single one of higher quality has no
analogue in classical networking and as such, this transforms the way in which
we will consider future algorithms for routing entanglement. We outline the
differences that arise because of this, demonstrate some elementary formalisms
for `multi-path entanglement routing', and discuss the philosophical
differences that arise when comparing this regime to conventional digital
network theory. We also present a software package, QuNet, that uses novel
`quantum cost-vector analysis' to simulate and benchmark routing in multi-user
entanglement networks in a way that is is highly scalable in network size and
the number of competing users. Our software accommodates both ground- and
space-based networks, and implements efficient multi-user time-optimisation for
mitigating congestion when quantum memories are available.
