Using remarkably simple experimental techniques it is possible to gently break a metallic
contact and thus form conducting nanowires. During the last stages of the pulling a neck …

Johnson noise thermometers infer thermodynamic temperature from measurements of the
thermally-induced current fluctuations that occur in all electrical conductors. This paper …

Since the advent of atomic force microscopy, mechanical resonators have been used to
study a wide variety of phenomena, including the dynamics of individual electron spins …

The existence of fractional charges carrying current is experimentally demonstrated. Using a
2D electron system in a high perpendicular magnetic field we measure the shot noise …

Remarkable advancements in coherence and control fidelity have been achieved in recent
years with cryogenic solid-state qubits. Nonetheless, thermalizing such devices to their …

We report low-temperature shot-noise measurements of short diffusive Au wires attached to
electron reservoirs of varying sizes. The measured noise suppression factor compared to the …

A spectrum analyzer with a sensitivity better than few pV/Hz in voltage noise measurements
and better than 1 fA/Hz in current noise measurements is presented. It has two distinct and …

We have measured shot noise in aluminum atomic point contacts containing a small number
of conduction channels of known transmissions. In the normal state, we find that the noise …

We show experimentally that even when no bias voltage is applied to a quantum conductor,
the electronic quantum partition noise can be investigated with GHz radio frequency …

Quantum physics emerge and develop as temperature is reduced. Although mesoscopic
electrical circuits constitute an outstanding platform to explore quantum behaviour, the …
