I am new to the quantum world, and I have 2 circuits that measure cosine similarity between 2 binary vectors. One uses a swap test, the other uses something called a hyper-state generation procedure.
So the first circuit needs a lower number of basic gates (i.e. CX and U gates) but it requires double the size of qubits compared to the second circuit.
So my question is, which would introduce more noise while running on a real quantum computer, the circuit with a high number of qubits, or the circuit with a high number of gates?
