In Pennylane, it’s possible to implement a CNOT gate between any two qubits. However, is it feasible to implement a CNOT gate across qubits on a real quantum computer?
It sure is possible to put CNOT gates on a real quantum device . Is there a particular device you want to use? Some devices may not allow certain qubits to “talk” to each other just because of the device’s topology. But it’s usually not a big deal (there are tricks to work around it ).
