Talk:Phase qubit

Okay, it is a nice article about the Josephson junction, but I still have no idea how the phase qubit works? How is the information saved there? edit: Never mind, I found it in the end. Is the spectrum harmonic? Because it kinda looks like this to me? If not, where does the anharmonicity come from? 134.60.83.75 (talk) 13:23, 17 September 2014 (UTC)
