Ask HN: What do you think about quantum computing
5 comments
we are still at the start of it and its coming but i feel that once we understand the math of how to braid particles better we will be ablee to build the first working models. from there the applications and algorithms will follow. i think whats interesting about quantum computing is that i dont see traditional companys operating them. i think its going to be led by research institutions that are not going to be intent on destroying us like the big tech companys.
More important question is when to think about quantum computing.
I think the hype does not quite cover the use cases it provides.
It is not ordinary computing, is applies to a very limited set of problems.
The buzz is that it is strong at cracking cryptography, but that's about it with what we have today. The rest is scientific exploratory statistics.

It's an academic exercise at the moment. Whether it becomes genuinely useful only time will tell.
The classic example, though, is factoring large numbers using Shor's algorithm. In order to do this, you have to rotate qubits many times at very small angles, which would instantly be wiped out by noise. I doubt Shor's algorithm will ever work for large numbers.
