In the race for quantum volume
Such a measure of quantum volume - dear to IBM - is an indicator of the overall power for quantum computing which does not only take into account the number of physical qubits, but elements such as the number and precisely the connectivity of the qubits, the rate of errors.

It is indeed a challenge to assess the power of a quantum computer. It is not a question of the number of operations per second, and this is also why the comparison with a classic computer is not easy, it will depend on the type of calculation to be performed.
We can still say that an ideal quantum computer has its power which increases exponentially with the number of Qubits.
I think it should go really fast in the next 10 years, for the hardware. For algos, it's been at least 20 years since research started, because we can simulate a quantum computer with a classical computer (obviously less speed). But from there to there being loads of tools available to develop large, practical applications, and well-trained developers, I'm less optimistic.
