Decomposing complex systems into smaller abstract functional blocks and developing mathematical models to represent their behavior is an important activity towards developing comprehensive system understanding. In this paper, we extract an essential functional block known as Bell State Measurement from a notional quantum network system implemented using linear quantum optics. Bell State Measurement is required for the geographic distribution of unknown quantum states via quantum teleportation and entanglement swapping. A statistical model is developed to estimate the probability of successfully sending an unknown quantum state across a quantum network segment using entanglement swapping. The abstract model greatly simplifies the performance analysis of a quantum network in terms of its throughput. This paper is introductory in nature and is intended to help those who are relatively new to modeling, simulating, and analyzing ideal quantum networks.
