    • The waveguides are designed such that the cut-off wavelength for higher-order modes is very near to the design wavelength in order to maintain a large waveguide core size

    • We cannot measure the four zero coherences in the density matrix (although they are limited by the small |11〉〈11| population) or distinguish between non-maximal coherences and rotated coherences with imaginary components for the |20〉〈02| and |02〉〈20| terms. However, neither of these effects changes the state fidelity. We have assumed a worst-case scenario throughout, i.e, we assume that the |11〉 component inside the interferometer makes no contribution to twophoton detection in T0 or T1
