# What is the actual precision of the IBM quantum computer?

In working with the IBM quantum computer, one can use for example the composer in order to build simple quantum algorithms. Essentially, one usually feeds a phase in order to affect one of the qubits. While for instance phases like $$\pi/2$$ can be applied "faithfully" into the real backends, one can add in the composer phases like 0.0983498491221321  (i.e. Float64).

I would like to ask what is the actual "precision", i.e. up to which significant figure does the real backends can achieve. I suppose it also depends on the backend that one chooses, so it should be a list of how much precision we can achieve in each one of the real machines.
