The Grand old Duke of York | He had ten thousand men;
He marched them up to the top of the hill and he marched them down again.
And when they were up, they were up | And when they were down, they were down
And when they were only halfway up, they were neither up nor down:
They were instead in a superposition of quantum states |up> and |down>
That concludes the lecture. For homework, please calculate the expected distribution of the 104 men at 'halfway', assuming a hill 100m high. Next week: Jack and Jill: entanglement or simple coupled system?
