HSBC Claims Quantum Trading Breakthrough
- sgt101 1y agohttps://arxiv.org/pdf/2509.17715 https://arxiv.org/pdf/2509.17715 for the paper. - this is back testing. - the mechanism (from first skim) is to create features using the QC which are then fed to the classical algorithm.
- dash2 1y agoCan anyone explain why creating features with QC might be a good idea?
- sgt101 1y agoI am on really shaky ground, but I think that they are representing "uncertainty" in the QC sense per event and that they claim that over the totality of the events this then represents reality better than stochastic sampling. But I've been reading the paper on and off today and I don't really understand much of it at all.

- miles7 1y agoNot 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.
