&nbsp;<\/strong>We employ quantum-volume random-circuit sampling to benchmark two- QPU entanglement-assisted distributed quantum computing (DQC) and compare it with single-QPU quantum computing. &nbsp;Based on our error model, we derive &nbsp;an analytical approximation of the average gate fidelity and show the one-to-one correspondence of three figures of merits, namely average gate fidelity, heavy output probability, and linear cross-entropy, which is shown to align with numerical simulations. The approximation is calculated from the extended connectivity graph of a DQC device. Furthermore, we provide a simple formula to estimate the average gate fidelity, which also provides us with a heuristic method to evaluate the scalability enhancement in DQC, and unveils the scalability enhancement in DQC for the QPUs with limited connectivity.
