How Big Is the Proton?

Thursday, October 31st, 2013

Interesting discussion of a sort of aberrant hydrogen atom that has a proton and a muon as opposed to an electron. Since the muon is much heavier than the electron it sits much closer to the proton giving a sense of its shape. One can only imagine what muonic helium would look like with two of these things.

Quantum physics: A grip on misbehaviour : Nature : Nature Publishing Group

Thursday, September 12th, 2013

Interesting discussion of how to tell apart classical and quantum systems using Bells inequality. The basic idea is finding more correlated events between two separate
systems than one might expect classically were they are decoupled. This implies that there is a quantum characteristic to the system. This fact can be exploited to measure the degree to which two systems are behaving as a “quantum unit” in relation to cryptographic applications and large-scale quantum
computation.
