The non-dissipative nonlinearity of Josephson junctions converts macroscopic
superconducting circuits into artificial atoms, enabling some of the best-controlled qubits …

The modern primary voltage standard is based on the ac Josephson effect and the ensuing
Shapiro steps, where a microwave tone applied to a Josephson junction yields a constant …

Superinductors have a characteristic impedance exceeding the resistance quantum RQ≈
6.45 k Ω, which leads to a suppression of ground-state charge fluctuations. Applications …

We report development and microwave characterization of rf SQUID (Superconducting
QUantum Interference Device) qubits, consisting of an aluminium-based Josephson junction …

A single Josephson junction in the phase-slip regime exhibits Bloch oscillations in the
voltage when biased with a dc current I dc. The frequency of the oscillation is given by π I …

We develop a general perturbative computation of finite-frequency quantum noise that
applies, in particular, to both good or weakly transmitting strongly correlated conductors …

Synchronization of Bloch oscillations in small Josephson junctions (JJs) under microwave
radiation, which leads to current quantization, has been proposed as an effect that is dual to …

A central problem in understanding the superconductor-insulator transition in disordered
superconductors is that the properties of grains and intergrain medium cannot be …

Bloch oscillations in a single Josephson junction in the phase-slip regime relate current to
frequency. They can be measured by applying a periodic drive to a dc-biased, small …

We develop and exploit an out-of-equilibrium theory, valid in arbitrary dimensions, which
does not require initial thermalization. It is perturbative with respect to a weak time …
