Quantum Many-Body Physics of Qubits

The ongoing development of superconducting qubits has brought some basic 
questions of many-body physics to the research forefront, and in some 
cases helped solving them. I will address two effects in quantum 
condensed matter highlighted by the development of a fluxonium qubit. 
The first one is the so-called cosine-phi problem stemming from the 
seminal paper of Brian Josephson: the predicted there phase dependence 
of the dissipative current across a Josephson junction was observed in a 
fluxonium, after nearly 50 years of unsuccessful attempts by other 
techniques. The second one is the dynamics of a weakly-pinned charge 
density wave: we predict that the dynamics may be revealed in 
measurements of microwave reflection off a superinductor, which is a key 
element of the fluxonium.
