Quantum mechanics allows one to compute in a way fundamentally different from any way to compute classically, at least in theory.(adsbygoogle = window.adsbygoogle || []).push({});

Will quantum field theory allow new kinds of computing that go beyond quantum computing? I would have suspected not, but for example this paper argues that it may. (It looks non-crackpot to me, but I have no way to verify its correctness.)

If so, will quantum field computation ever be of practical use? Will making use of it be feasible, or feasible only for Jupiter-sized-brain-with-galaxy-sized-accelerator type entities, or physically impossible, or logically impossible?

Would it have any implications for fundamental physics, computational complexity theory, or the foundations of mathematics?

Any insights, information, or pointers to information on this? Thanks in advance.
