What kind of mathematics is common in quantum computing?



From what I have seen so far, there is a lot of linear algebra. Curious what other kinds of maths are used in QC & the specific fields in which they are most predominately invoked.

1This question is really, really broad. As the current answer shows, pretty much any and all maths can be used in QC. – heather – 2018-07-16T18:18:13.410

@heather I did not realize that when asking. I think it serves as a good reference for the future tho. – user820789 – 2018-07-16T18:37:23.043

2How can you edit an existing question such as to completely reverse its meaning? This makes all answers void! – Norbert Schuch – 2018-07-19T12:23:26.713

1As @NorbertScuch's comment above, it's not a great idea to edit a question to such an extent after it has a valid answer as this invalidates the answer, so I'm reverting the edit. Normally, I'd say to ask a separate question but in this case, it would still be too broad/off-topic by virtue of essentially being a 'shopping list question', so you'd be better off asking that sort of thing in [chat], if there's someone there willing to answer – Mithrandir24601 – 2018-07-19T12:45:28.383

1is there any area of mathematics for which you cannot see any possible connection to qc? – user820789 – 2018-07-15T08:07:42.087

2I've been thinking about it since seeing your question! – user1271772 – 2018-07-15T08:08:09.307

2I can't think of a lot of examples where vector calculus comes up. But they're the heart of Maxwell's equations, which you'd use if you're implementing an optical quantum computer. – user1271772 – 2018-07-15T08:27:14.400
