Iโ€™m saying that if time is quantized and discrete, then the mathematical substrate required for computation does not exist in the way the formalism assumes. QC relies on continuous-time unitary evolution to define superposition, phase accumulation, interference etc. If time has a smallest indivisible tick, that formalism breaks; this is well known in mathematical physics and has been the core known problem. Differential equations cease to be fundamental; coherence across infinitesimal intervals is undefined with an atomic tick. What remains are discrete update rules, not a scalable computational substrate. So QC as a model of computation with asymptotic power (e.g. Shor), requires an assumption about time that may not be true. If time is discrete, QC reduces to an effective, limited approximation, not a fundamentally new computational class. Thatโ€™s not controversial. Discrete time breaking continuous-time QM/QC is a known result. Youโ€™re welcome to fact-check that. I will wait for you to do so.

So what is your actual position on quantum advantage? a) It does not exist, it is a hoax b) It does not exist, it is a misunderstanding, misreading, etc. c) It does exist, it's a real thing, but is never going to be powerful enough to crack keys and such (works but lack of use case) Which is it?
