Not at all clear from the paper whether you need a quantum computer to do these calculations or whether the same circuits could be simulated classically.
(I.e. from what I can see the paper never mentions the amount of entanglement or complexity in the quantum state, or that they used state-of-the-art simulation techniques like tensor networks to check.)
If someone knows of a blog post, supplemental material, etc. that reports this I'd be curious to know.

[ 2.6 ms ] story [ 27.1 ms ] thread- this is back testing. - the mechanism (from first skim) is to create features using the QC which are then fed to the classical algorithm.
