When a control parameter of a system is suddenly changed,
the accessible phase space changes too and the system needs
its characteristic relaxation time to reach the final
equilibrium distribution. An important and relevant question
is whether it is possible to travel from an equilibrium
state to another in an arbitrary time, much shorter than
the natural relaxation time. Such...

The adiabatic manipulation of quantum states is a powerful
technique from quantum optics and atomic physics. Previous
work on the Autler-Townes effect in superconducting phase
qutrits [1], on Stueckelberg interference [2], and on the
effect of motional averaging in transmons [3] has added
evidence that superconducting circuits truly behave as
controllable artificial atoms. Here we...

We report on the realization of a single-electron source,
where current is transported through a single-level quantum
dot (Q) tunnel coupled to two superconducting leads (S).
When driven with an ac gate voltage, the experiment
demonstrates electron turnstile operation. Compared to the
more conventional superconductor–normal-metal–superconductor
turnstile, our superconductor–quantum-dot–...
