::Yes, at first I thought the part about modular exponentiation made sense if you're looking at the slightly modified version using phase estimation, but yes it is ballony.
::I also am not sure why you felt changing my edit of exponential back to sub-exponential? I really think the definition of sub-exponential including things like O(2^(n^k)) for 0 < k < 1 is a bit misleading. There are problems that are complete in EXP-time that take "sub-exponential" time if you use this definition (poly reductions still get you any exponential function) which sounds just wrong!

ReferenceExpander

Just a friendly heads-up in case you weren't already aware, since it's installed on your common.js: Careless use of ReferenceExpander has caused serious problems. It's currently at MFD, and a large cleanup project is underway to repair the citations damaged by the script. I and several other users have !voted that the script be deleted or disabled, and I wouldn't recommend using it at all unless you thoroughly check every reference it modifies against the previous revision. If you're interested in a more detailed explanation of the script's issues, Folly Mox has provided an excellent summary at the MFD. — SamX [talk · contribs] 05:03, 1 June 2023 (UTC)[reply]

The shors algorithm edit

can you explain what you meant by ballony? I don't see a problem with how it was before your edits Quantumly (talk) 00:22, 7 June 2023 (UTC)[reply]

The bit about Shor’s being efficient because of modular exponentiation was baloney. That operation is what makes shores so inefficient in terms of circuit complexity O(n^3). The binary Fourier transform is also not an efficiency. What makes Shor’s efficient is quantum parallelism and constructive/destructive interference. This allows a readout with significant probability of being a multiple of the order of the subgroup. Jehochman Talk 01:47, 7 June 2023 (UTC)[reply]
Yes, at first I thought the part about modular exponentiation made sense if you're looking at the slightly modified version using phase estimation, but yes it is ballony.
I also am not sure why you felt changing my edit of exponential back to sub-exponential? I really think the definition of sub-exponential including things like O(2^(n^k)) for 0 < k < 1 is a bit misleading. There are problems that are complete in EXP-time that take "sub-exponential" time if you use this definition (poly reductions still get you any exponential function) which sounds just wrong!
