CNOT gate has actually been built or not?

    Could somebody tell me whether or not a CNOT gate has actually been built or not?

    I believe there are several CNOT physical realisation up to today. One of them:

    Yes, Controlled-NOT gates have been made, even teleported, and several quantum circuits implementing them studied. Here's one proposed quantum circuit, a variation of the "quantum multiplexor circuit", using CNOT gates
    Another quantum circuit using CNOT gates is the Brassard teleportation circuit
