Although “Quantum” means digital, quantum processing is not digital, as in integers. Why?
- Fuzzy vs Determinative (Probabilty vs Certainty)
Quantum processing gives fuzzy, varying, statistical, non-replicable, erratic, or analog answers.
Digital computing by contrast gives explicitly digital, replicable exact answers.
Example: Wind Speed Estimation vs Password Cracking
We simply can’t crack a lost password with analog, non-replicable or fuzzy answers.
But for problems that don’t need exact answers like estimating wind speeds, quantum computing may(?) be worthwhile. Or for many-dimensional problems involving millions of variables like weather modeling they might someday be helpful.
2. Quantum Error Correction is Unsolvable
There is no such thing as Determinative Quantum Memory
Just as quantum processing results are fuzzy, the errors it produces are also fuzzy. And can’t be moved to or processed with digital memory.
3. Quantum Computers Cannot Exist without Determinative Quantum Memory
. . . which does not exist (See #2 above).
So why are you throwing good money at Science-Fiction?
