Has there been any measurable progress in quantum computing over the last few decades? Not just number of qubits, but also factoring in speed and error correction.

In classical computing, there’s Moore’s law. Is there anything roughly similar in quantum computing?

Is quantum volume per second going up over the years? If so, what is the rate of change of this metric? Is it doubling every year or two?

You’re right. I see graphs of quantum volume over time over the last few years, and they are exponential. Thanks.

But the only graphs I saw were from individual companies. I haven’t yet seen any graphs from independent rating agencies or academic papers comparing different companies quantum computers.

Also I haven’t yet seen anything about quantum volume per second. Quantum information can be stored for hundreds of milliseconds, then noise takes over, and you have to reset everything. How long does it take to set up the next shot on different quantum computers? Quantum volume per second would also incorporate the time needed to set up the next shot.
