Alexandre Blais, Associate Professor in the Physics Department at the Université de Sherbrooke, gave a lecture about Quantum Computing with Superconducting Qubits.
The lecture is the first of two parts, and was filmed at the Canadian Summer School on Quantum Information, held at the University of Waterloo in June of 2012.

It is a great explanation of the superconducting qubits and the multi-qubit architecture. I was wondering what are the current trends are with artifical atoms that are being developed for the Quantum Computers.

@ 21:04 I would actually go the other way, and call Q^2/2C as the potential energy, since it is the electromagnetic potential energy stored in the system, and 1/2 C omega^2 Phi^2 as the kinetic energy, since Phi is associated with the momentum of the electrons. You can redefine the mass.

Great tutorial. Are there any good introductory textbooks/references on this material? I have decent background in electrical engineering, and basic understanding in quantum mechanics.

Hi, very interesting lecture. I would like to ask what appened to the quadratic part of the hamiltonian at , more or less, 15:54. I mean, if the hamiltonian depends by the squared flux divided by the Josephson inductance it should yield flux squared times the cosine of the flux instead of the cosine only. Shouldn't it?

I have exactly the same doubt .

The Inductance of the Josephson Junction derived there is only used to give an idea of what an effective Inductance would look like in a non-linear device like the JJ. The instantaneous JJ energy will not be given by phi^2/2 L_J because that expression assumes a linear relationship between current and flux. The cosine form of the JJ energy is the exact answer when the instantaneous power P=IV is integrated over time.

To have the qubits uncoupled for a long time and to design self-error correcting algorithm is the most immediate problem for making quantum computers (in room temperature).
