What does a tangible Quantum-Gate look like?
You seem to have the idea that a quantum gate is a physical thing rather than just a conceptual thing. It doesn't  necessarily work that way. While CMOS  gates are usually actual physical devices, quantum gates may be just conceptual. 

Consider an ion trap. The ions represent qubits by using one electronic state as a $|0\rangle$ and another as a $|1 \rangle$. A quantum gate is performed by applying a $4 \times 4$ unitary matrix to two of these ions. This is done by shining a sequence of laser pulses on the ions. It's not a physical device into which two ions are input, in which they interact, and out of which the ions come with their states changed. 

Quantum gates are performed by shining laser pulses on the ions, but there's not necessarily one laser per quantum gate—the same lasers are used for many different quantum gates. Thus, you can't point to any specific piece of hardware and say "this is the quantum gate".  

And if you use flux qubits in superconductors for your quantum computer, the quantum gates don't use lasers at all, and they look completely different (and slightly more like CMOS devices).
