I am familiar with logic gates which are in classical computers. They are made up of semiconductor devices like diodes and transistors.
There are some companies which are working on the universal quantum computers such as Google, IBM, Honeywell.
How does quantum logic gates such as Pauli-X,Y,Z, Hadamard, CNOT, CCNOT look like in the circuits of those universal quantum computers? I have referred to many white papers, but in all of them I saw them representing these gates as matrices.
Are Quantum logic gates even physically realized yet OR are they only theoretically proved using matrices?
Can you please attach some real picture of these processors, and point out the quantum logic gates?
