Now we're getting somewhere. Complex numbers are quite useful for engineering; without them it would be impossible to do something simple like design a Tcebychev filter, some of the coolest use of complex math there is. I'm saying only, there are inappropriate places to use it, and making the speed of light proportional to time would be one of those situations. We really do need an entanglement clock before an entanglement based hypercomputer is going to work. An XOR gate almost resembles an entanglement test (anti coincidence) all by itself, like it could be an entangled/not entangled gate used for synchronization of the qubits. Could we make an XOR gate system synchronized to observation? It has to be photonic, unless Delft can do it with Majorana fermions and superconductors. Entangled photons are easier to adjust timing with fiber optics. Observing an entangled state is going to simultaneously flip the state of one (or all) of the other entangled states. An entanglement gate would have to do this, even if this isn't necessarily what it is you wish to happen.
