The on-demand generation of pure quantum excitations is important for the operation of quantum systems, but it is particularly difficult for a system of fermions. This is because any perturbation… (More)

We study the injection $n$ of electrons in a quantum conductor using voltage pulses applied on a contact. We particularly consider the case of Lorentzian voltage pulses. When carrying integer charge,… (More)

We present an original statistical method to measure the visibility of interferences in an electronic Mach-Zehnder interferometer in the presence of low frequency fluctuations. The visibility… (More)

We have determined the finite temperature coherence length of edge states in the integer quantum Hall effect regime. This was realized by measuring the visibility of electronic Mach-Zehnder… (More)

An electronic Mach-Zehnder interferometer is used in the integer quantum Hall regime at a filling factor 2 to study the dephasing of the interferences. This is found to be induced by the electrical… (More)

We report on measurements of the quantum capacitance in graphene as a function of charge carrier density. A resonant LC-circuit giving high sensitivity to small capacitance changes is employed. The… (More)

This work is devoted to the study of decoherence process in the integer quantum Hall regime. In this regime, the current is carried by one dimensional chiral edge channel. These electronic beams are… (More)

The complete knowledge of a quantum state allows the prediction of the probability of all possible measurement outcomes, a crucial step in quantum mechanics. It can be provided by tomographic methods… (More)

We investigate the crossover between weak localization and weak antilocalization in InAs nanowires of different diameters (75 nm-140 nm-217 nm). For a magnetic field applied perpendicularly to the… (More)

In this report we review the present state of the art of the control of propagating quantum states at the single-electron level and its potential application to quantum information processing. We… (More)
