Turing Machines can simulate binary search, in the sense that they can compute whatever you can compute using binary search. You seem to be confusing computability and complexity, which are two different things.

Roughly speaking, comparability is about what we are able to compute in a given model of computation. We believe Turing machines to be an universal model of computation. All powerful-enough (i.e., Turing complete) models are equivalent to a Turing Machine.

Complexity is about how long it takes to compute something (actually, this is not restricted to time). Different models of computation are not necessarily equivalent complexity-wise.
