entanglement in quantum repeater networks is the management
and suppression of quantum errors. In this work, we develop an
approach for extending the effective coherence time of shared
entanglement between nodes by utilizing compact quantum error
correcting (QEC) codes, which are scheduled and run locally on
resource-constrained repeaters, to maximize the fidelity of the shared state,
while also accounting for the incurred gate noise from QEC circuit
operations. This local QEC approach stabilizes the distributed state
via local operations, so independent execution on the nodes requires
no additional synchronization or protocol overhead. Simulation
results show significant improvements in the effective coherence
time relative to idle decay, suggesting this approach could be useful
with several quantum networking protocols such as entanglement
generation, swapping, purification, and teleportation.
