To catch and reverse a quantum jump mid-flight
In quantum physics, measurements can fundamentally yield discrete and random results. Emblematic of this feature is Bohr’s 1913 proposal of quantum jumps between two discrete energy levels of anExpand

Electron–electron correlations in carbon nanotubes
Single-wall carbon nanotubes, are ideally suited for electron-transport experiments on single molecules because they have a very robust atomic and electronic structure and are sufficiently long toExpand

Persistent control of a superconducting qubit by stroboscopic measurement feedback
Making a system state follow a prescribed trajectory despite fluctuations and errors commonly consists of monitoring an observable (temperature, blood-glucose level, etc.) and reacting on itsExpand

Magneto-electric Aharonov–Bohm effect in metal rings
The quantum-mechanical phase of the wavefunction of an electron can be changed by electromagnetic potentials, as was predicted by Aharonov and Bohm in 1959. Experiments on propagating electron wavesExpand

Coherent oscillations inside a quantum manifold stabilized by dissipation
Manipulating the state of a logical quantum bit usually comes at the expense of exposing it to decoherence. Fault-tolerant quantum computing tackles this problem by manipulating quantum informationExpand

Fluxonium-Based Artificial Molecule with a Tunable Magnetic Moment
Engineered quantum systems allow us to observe phenomena that are not easily accessible naturally. The LEGO-like nature of superconducting circuits makes them particularly suited for building andExpand

Conduction channels of superconducting quantum point contacts
Atomic quantum point contacts accommodate a small number of conduction channels. Their number N and transmission coe$cients M„ n N can be determined by analyzing the subgap structure due to multipleExpand

The Proximity Effect in Mesoscopic Diffusive Conductors
The “proximity effect” is a loose term describing the presence of a superconducting order in a piece of normal metal (N) placed in electrical contact with a superconducting one (S). Because of anExpand
