Integration of charge sensors for the readout of semiconductor quantum bits (qubits) is required for a realistic realization of scalable quantum computer. Such charge-sensitive devices, however, involve a significant overhead in terms of gates and contact leads, posing an issue for scalability ... Lire la suite »

The development of sensitive and compact readout tools of quantum states is a central issue in the run to industrial scalability of semiconductor quantum bits (qubits). We employ the gates of industrial silicon Field-Effect Transistors (used as qubits) as radio-frequency resonators integrated in ... Lire la suite »

Moiré patterns are superlattice structures that appear when two crystals with a lattice mismatch or with a different orientation are superimposed. We have developed a universal classification of all possible periodic Moirés in order to determine their exact crystallographic ... Lire la suite »

Leti, an institute of CEA Tech, along with Inac, a fundamental research division of CEA, and the University of Grenoble Alpes have achieved the first demonstration of a quantum-dot-based spin qubit using an industry-standard fabrication process. Published in the November 24 issue of Nature ... Lire la suite »

Nanowire transistors in the sub10 nm range are subject to process variability. A main cause is the surface roughness of the nanowire. A single dopant centered in the channel can also modify the room temperature electrical characteristics of the transistor.  Both the surface roughness and a ... Lire la suite »

Atomically clean superconducting graphene has been grown on thin rhenium films. This breakthrough paves the way to new hybrid superconducting nanostructures.   Graphene is not an intrinsic superconductor but can become superconducting by proximity effect when it is intimately connected ...
