There's been quite a flap about P.M. Trudeau's attempt to explain QC.

I don't find Trudeau's interest or understanding surprising at all; politicians are in a "superposition" of positions all the time -- e.g., certain U.S. politicians being both for the Iraq war and against it; being for the TPP and against it; being for both $12/hr and $15/hr minimum wage.  Many DoD programs are like Schrodinger's cat -- they can't stand too much public scrutiny, else they may die.

Unless the Fourth Estate holds their feet to the fire, "measures" them and forces a collapse of these superposed states, these politicians can remain in a superposed state for months or years.

"One of the greatest challenges is controlling or removing quantum decoherence ... Currently, some quantum computers require their qubits to be *cooled* to 20 millikelvin in order to prevent significant decoherence." -- Wikipedia

We always suspected the "coolest" politicians of having ice water in their veins; but 20 millikelvin (hydrogen) ice ?  Perhaps we've had QC's with long decoherence time in the form of politicians for hundreds of years; who knew?

What seems to have been lost in this flap is the serious money that is going into QC research.

Apparently, Canada desperately wants to be the birthplace of the first real QC (hint: but not in British Columbia).
