“Typically, gates built on photonic platforms to manipulate quantum information encoded in separate photons work only some of the time because photons naturally don’t interact with each other very well, making it extremely difficult to manipulate the state of one photon based on the state of another. “”
Photons must learn to play together. I suggest doubling the qudit count within the space by a factor of 24 to the 6th power. If that doesn’t work, blame Deutsch’s algorithm, erase the board and go out for margaritas.
