No, quantum gates work differently than electrical gates. Hadamard do super position, include a CNot and you get entanglement. With entanglement you get spooky action at a distance. And if someone tries to intercept your communicate you can detect it.

It's like saying electronics are fake, if they were the circuits would not work. Same with quantum circuits
Also the gates have be to be reversible, you need ancilla qubits.
QPUs though are only applicable where speed-up can occur, not generally
