A reporter tried to trap Justin Trudeau (the dreamy PM of Canada according to Ms. Rabett) by asking if he could explain quantum computing and Trudeau provided a serviceable answer
Eli would like to riff off this in a slightly different way.
Generally speaking there are two types of problem solvers, the sequentialists who grind things out one step and a time. A normal computer is like that.
The other style is to build a complex mental model of the problem that allows for a one step solution. That is quantum computing.
In the world of quantum electrodynamics, Julian Schwinger was the grinder and Richard Feynman the visionary.
