We evaluate the reliability of the move operation specific to a quantum distributed computer. We vary the noise strength for noisy operations and the fidelity of the initial EPR pair for an EPR distillation protocol. The noise model employed is depolarizing quantum channel. The protocol analyzed is a tradeoff between the serial purification and the tree based purification protocols - a 5 level queue protocol. Our analysis employees simulated fault injection to determine the efficiency and reliability of the purification protocol, and it uses analytical results to estimate the reliability of the operation responsible for data movement. We show that noise affecting the quantum gates acts as a limitation factor for the fidelity of the purified EPR pair independent of the number of purification levels.
