Its thinness, too, gives it unusual electrical properties.One of these is that if it is placed in a magnetic field it exhibits a phenomenon known as the relativistic quantum Hall effect.

In principle, by putting a set of entangled qubits into a suitably tuned magnetic field, the optimal solution to a given NP-complete problem can be found in one shot.
