* The quantum volume treats the width and depth of a model circuit with equal importance and measures the largest square shaped (i.e., <math>m = d</math>) model circuit a quantum computer can implement successfully on average. | * The quantum volume treats the width and depth of a model circuit with equal importance and measures the largest square shaped (i.e., <math>m = d</math>) model circuit a quantum computer can implement successfully on average. | ||

* There are two possible paths for increasing the quantum volume, which is given by the numerical simulations for given connectivity. The first path is to prioritize improving the gate fidelity above other operations. This | |||
sets the roadmap for device performance to focus on the errors that limit gate performance, such as coherence and | |||
calibration errors. The second path stems from the observation that, for these devices and this metric, circuit | |||
optimization is becoming important. | |||
