Here, f is a phase shift intrinsic to the gate, and q(ϑ) is a corrective phase shift that can be applied by tilting an HWP at OA by an angle ϑ, such that f + q(ϑ) = 2np (see Materials and Methods). In doing so, we are able to test the coherent interaction of all three qubits in the gate, which is a ...
