intuitionistic math can help in quantum physics?

I’m not aware of any results delineating for which analytic functions this use of the Fundamental Theorem of Calculus does not improve on numerical integration, but that sounds like an interesting question.

As I read Kreinovitch's paper, similar ideas came to Mind.

I once gave a lecture, to a group of high level researchers in
analysis, presenting  an overview of G. Takeuti's work on
computational complexity within bounded arithmetic. They were all
captivated by Takeuti's ideas, and one of the conclusions we all
reached, was the following: the problem of sieving exponential space,
is analogous to that of representing an "almost nowhere differentiable
function", by a fourier series.

Algorithms were proposed, in this context, as candidates for a quantum
speed up, similar to those of Simon and Shor.
