Quantum roadmaps target million-qubit systems within three to five years
“So right now the holy grail, if you will, of quantum is say a million physical qubits to implement perhaps thousands of logical qubits. And that's where you start to get real science and real applications. And if you look at all the company roadmaps, that is t…”

Rolls-Royce found quantum fluid dynamics outperformed theoretical predictions
“Rolls-Royce, who makes very good jet engines, are starting to examine what they can do for their computational fluid dynamics programs, what quantum can bring to the table. It was interesting. They got some cool results, but what I really liked about their exp…”

Assertion Supported
Leading scientific supercomputers cost up to $700M plus $300M in power
“Some of the most expensive HPCs right now doing science and engineering work are costing six to seven hundred million dollars a pop. And they require perhaps two to three hundred million dollars of electricity to run over a five year period.”
