Missions

Coherent manipulation of single electrons in solid-state devices is attractive for quantum information purposes because they have a high potential for scalability. Depending on the system used, the charge or the spin may code binary qubit information. A particular appealing idea is to use a single flying electron itself as the conveyor of quantum information. Such electronic flying qubits allow performing quantum operations on qubits while they are being coherently transferred. Information processing typically takes place in the nodes of the quantum network on locally controlled qubits, but quantum networking would require flying qubits to exchange information from one location to another. It is therefore of prime interest to develop ways of transferring information from one node to the other. The availability of flying qubits would enable the possibility to develop new non-local architectures for quantum computing with possibly cheaper hardware overhead than e.g. surface codes.

Activities

The aim of this research project is to participate in an ongoing research project to realise flying qubit architectures using single-electron wave packets. Using a Mach Zehnder interferometer will allow to manipulate the single-electron wave packet in flight. The missing brick in such a flying qubit architecture is a single-shot single-electron detector that is able to detect the single electron wave packets in flight. This could be achieved by exploiting the extreme sensitivity of a quantum sensor. Using such a detector we intend to realize full quantum operation of a flying qubit using individual electrons.

Skills

The candidate should have a strong background in quantum mechanics and solid-state physics and experience with experimental physics. Skills in cryogenics, optics, radio-frequency electronics or programming (python) would be an asset.

Work Context

The Néel Institute - one of the largest French national research institutes in condensed matter physics - is located in the heart of a unique scientific, industrial and cultural environment. It is part of one of Europe's biggest high-tech environment in micro- and nanoelectronics, right next to the French Alpes.
