I'm skeptical of something Neil Turok said, having to do with quantum information.
http://thetyee.ca/Books/2012/10/13/Neil-Turok-Universe-Within/
From what I understand, a qubit can store an infinite amount of information. So, where does he get the number 300 from? Why not just one? Also, can't the three-dimensional position of a particle can be classically recorded to the limit of infinite precision? Is there some limit at the Planck length? Any help/clarification would be appreciated.

It turns out that if you take just 300 electron spins and couple them together into a quantum computer, then the amount of information it would be capable of handling is the same as that in the position of every particle in the whole universe. There are about 10 to the power of 90 particles in the universe and if you use each one of their three-dimensional positions and imagine recording all of those positions, that's about the same as what you would get from just 300 electrons in a quantum computer. So it really is on a whole different scale from anything we can visualize in our mind.
