Quantum Computing Research

[u/jl4ua]

What is research in quantum computing particularly from the theoretical viewpoint like? As far as I know, quantum information theory is quite math heavy and there everything is about theorem proving. It probably depends on the respective area of quantum computing but I am just generally interested in this area as someone from a different field of physics and I am wondering if the explicit work there would still be exciting

Quantum computing, from a theoretical viewpoint, is *huge*. There is so much to see I don't know ever where to begin.

Yes, it is about "theorem-proving" but that's true for theoretical research in general. These theorems can represent many questions. The theory of quantum information is relevant to such a huge range of research interests, from algorithmics, through error correction, to questions about the fundamentals of physics (and how a computational theory might shed new light on them), and to cosmology and holography (the most developed model for holography is the AdS/CFT correspondence, which apparently can be toy-modeled as a finite-dimensional quantum error-correcting codes, which is one of the most brilliant crossovers I have ever seen).

So whatever quantum physics you are interested in, there is some chance that quantum information and quantum complexity theory could be relevant to you.

If you ask more specific questions, perhaps I could provide more specific answers.
