He / she will develop a dual qubit integrated device for the processing of quantum information (simulation, expitaxis and fabrication)


The post-doc will be involved in the design and optimization of the growth of quantum dots heterostructures, in collaboration with Paola ATKINSON at the INSP (Paris) and in the fabrication of photonic structures in Rémy BRAIVE's team at C2N. (Palaiseau). The post-doc will work in close collaboration with the quantum optics group of INSP (Paris), where optical measurements of QD photonic devices will be performed.


- She / He must have demonstrated his skills in growth and clean room techniques.
- She / He should have a good knowledge of the physics of quantum dots and photonic crystals.
- Experience in low temperature optical measurements would be greatly appreciated.

Work Context

Quantum logic operations depend on the operation of a quantum information bit (qubit) and two-qubit ports requiring coherent interaction between pairs of qubits. For quantum and computer communication applications, it is advantageous to integrate many qubits on a single chip. The discrete state density of semiconductor quantum dots (QDs) and their ease of integration into conventional semiconductor device structures make it the ideal tool for quantum information processing applications ranging from single photon to spin qubit manipulation.

In this project, we will develop a two qubit integrated device for the processing of quantum information. This device will be based on In (Ga) As QDs placed deterministically at specific locations in a photonic crystal. The goal is to demonstrate a scalable design of a two-bit gate based on on-chip embedded connection bits.
