This analogy stops working, however, as soon as you add a second, or more quantum coins. You need more than one qubit to do efficient quantum computing and the same is true for a quantum algorithm recast into a quantum walk.

I guess that if you would use a HeNe in the actual experiment, you would get the same probability distribution. If true, this means that the "quantum" walk can also be exhibited by classical light, meaning, it is a wave phenomena. if so, how can a classical effect be used for quantum computing?
