Abstract
Various benchmarking metrics have been developed to quantify the performance of quantum computing hardware and help evaluate development. However, it is not always necessary to know the metric values precisely. This is especially true for potential end-users who may not be experts in the underlying technology itself. In this work, we show how to estimate the quantum volumetric metrics defined in Ref. [1] based on system parameters such as qubit number, qubit layout/connectivity, and physical error rates. As part of this work, we also include an initial analysis of how the overhead required for quantum error correction in systems below the error correction viability threshold affects the metric value of that system.
