Will light be the basis for quantum computing?

Using a compact optical platform that exploits the quantum characteristics of light, Professor Roberto Morandotti and his team are one step closer to realizing the first powerful photonic quantum computer. In Nature Physics, the INRS researchers revealed to have generated a particular class of quantum states - d-level cluster states, robust and powerful than any other such states demonstrated thus far -, as well as to have used them to implement novel quantum operations.
