Compilation with ScaffCC compared to Qiskit's Transpiler

I am new to ScaffCC and wanted to ask if ScaffCC has the ability to compile a program to a limited connectivity machine? Similar to Qiskit's Transpiler ability?

Qiskit: 3 applications of identity with arbitrary SU(2) is universal?

We know that the CNOT gate together with arbitrary SU(2) gates can be used to perfectly implement arbitrary SU(4) gates with 3 applications of the CNOT. I am using the Qiskit library and testing how ...

Would IBM's "compiler" turn my identity circuit into nothing?

If I were to create a circuit with the following gate: $$\tag{1}R_\phi = \begin{bmatrix} 1 & 0 \\ 0 & e^{i \phi} \end{bmatrix},$$ with $\phi$ specified to be equal to 0, then the gate that I ...
