As a newbie to Quantum, I was reading some of the articles and ran into a no-fast-forwarding theorem, which is described "Simulating the dynamics of a quantum system for time T typically requires Ω(T) gates so that a generic Hamiltonian evolution cannot be achieved in sublinear time. This result is known as the “no fast-forwarding theorem”, and holds both for a typical unknown Hamiltonian and for the query model setting"
Does this mean that "there won't be any shorter-time algorithm than the required T? I don't think I fully appreciate the implication or practical meaning of this.
Any help would be appreciated
