About QUINST

Quantum mechanics is at the heart of our technology and economy - the laser and the transistor are quantum devices - but its full potential is far from being realized. Recent technological advances in optics, nanoscience and engineering allow experimentalists to create artificial structures or put microscopic and mesoscopic systems under new manipulable conditions in which quantum phenomena play a fundamental role.

Quantum technologies exploit these effects with practical purposes. The objective of Quantum Science is to discover, study, and control quantum efects at a fundamental level. These are two sides of a virtuous circle: new technologies lead to the discovery and study of new phenomena that will lead to new technologies.

Our group's aim is  to control and understand quantum phenomena in a multidisciplinary intersection of  Quantum Information, Quantum optics and cold atoms, Quantum Control, Spintronics, Quantum metrology, Atom interferometry, Superconducting qubits and Circuit QED and Foundations of Quantum Mechanics.

Title: Advances in Graphene Spintronics

Abstract
Graphene, a single atomic sheet of carbon, has recently emerged as a promising new material for spin-based electronics (i.e. spintronics). Electron spin transport is the crucial functionality needed for spintronic devices. However, despite many years of effort in metals and semiconductors, spin transport in lateral devices has been hampered by small signals, cryogenic operating temperatures, and short spin diffusion lengths. In a short time, graphene has surpassed all other materials for lateral spin transport by exhibiting large  spin signals, long spin diffusion lengths, and gate-tunable spin  transport?all at room temperature. In this talk, I will highlight our key contributions toward establishing the nascent field of graphene spintronics. This includes the achievement of tunneling spin injection, long spin lifetimes in single layer and bilayer graphene, and the manipulation of spin transport by surface chemical doping.
