Pick simulation settings and hit run (see below for technical details).
Two processes occur in this system
nearest neighbors have entanglement being generated between them
each repeater performs an entanglement swap as soon as possible
In this simulation you can manipulate:
number of repeaters
number of qubits available as memories at each repeater
the mean time to successful generation of a raw Bell pair (governed by an exponential distribution)
the time it takes to perform a swap at a repeater
the fidelity of a raw Bell pair (assuming depolarization noise)
Tâ‚‚ memory time (only dephasing is modeled)
Local gates are assumed perfect.
To avoid deadlocks, entangled pairs are being generated only on even/odd pair of registers: for a given pair of neighboring repeaters a raw entagled pair can be stored only in odd registers on the left repeater and in even registers on the right repeater. This staggering makes it impossible for the concurrent processes of entangling generation and swapping to deadlock each other.
This simulation is a convenient tool for studying congestion on the repeater chain.
