The mind-bending complexities of quantum investing

THE brilliant physicist Richard Feynman once famously remarked that “nobody understands quantum mechanics” given the counter-intuitive absurdity of nature.

To which the pragmatic response of some other researchers has been to “shut up and calculate”. Even lesser minds than Feynman’s can sometimes prove in practice what remains mystifying in theory.

A similar reductionist view appears to have taken hold among investors trying to make money out of the current quantum boom. It is all too easy to get lost in the mind-bending complexities of the different modalities being explored to build a quantum computer.
