QUROPE Quantum Information Processing and Communication in Europe

Location

The position is initially for 1 year, extendable up to 3 years and is part of an international collaboration between the Institute Néel, Grenoble, France, IMEP/LAHC, Grenoble, France, and Tokyo University, Japan. Earliest starting date is January 2010.

The goal of our project is to realize coherent transport of a single electron spin in a scalable condensed matter system. Presently, one can achieve extremely high control of an electron spin using semiconductor lateral quantum dots, the elementary brick for spin based quantum computing. In order to manipulate and control spins individually on a large scale, one has to be able to coherently transport a single electron spin individually from one quantum dot to another, relatively distant quantum dot. Such an approach will open new possibilities to the field of Quantum Information with spin qubits and is an essential step towards coherent control of a large number of spin qubits. The project aims at developing quantum channels between quantum dots. It is hence essential to develop and optimize fast control and fast detection of moving quantum objects in nanostructures. The candidate will conceive and realize new nanostructures to enable to perform fast qubit operations as well as fast detection schemes in double dot systems (typically up to 10 GHz) of moving electrons in such nanostructures.

During his stay, the candidate will benefit from interaction with RF engineers of the Neel Institute and close collaboration with the Grenoble RF lab IMEP-LAHC. Samples will be fabricated at the state of the art nanofabrication facility PTA-Grenoble (MINATEC) with full technical support staff. Low temperature equipment (10mK, 16T) compatible with high frequency measurements is already operational.

The candidate will also be engaged in supervising PhD and/or internship students during his stay. The candidate should have a strong background/experience in at least one of the following fields: nanofabrication, cryogenics, transport measurements, spin physics.
