Questions tagged [quantum-volume]

Roughly speaking, quantum volume measures the worth of quantum computing hardware by the square of the maximum depth of quantum computations it permits but limits its value to the square of the qubits involved. This limit is justified by wanting to forestall "gaming" of the system by optimizing towards few qubits. (

Is the "Quantum Volume" a fair metric for future, elaborate, high value quantum computations?

A metric called the "quantum volume" has been proposed to somehow compare the utility of different quantum computing hardware. Roughly speaking, it measures their worth by the square of the maximum ...

How to calculate the quantum Volume?

I read the article of IBM on Quantum Volume, but I don't understand how to calculate the effective error rate, and therefore the Quantum Volume. Can someone give an example of the calculation?
