Could be, but not currently nor in near future. If/when QC would be able to solve a whole lot of complex integrals (big if), this potentially could allow us to simulate different quantum equations and construct and check different universe models, which, if proven valid, could lead to some theory of everything, which then could lead to exploration of some weird physics that allows for FTL or at least near light speed travels.

But, as you can see, there's a whole lot of ifs, each one bigger than other.
