Sujet de stage:

Quantum computing is seen as a disruptive technology that could pave the way to the design of new computers able to solve problems out of reach of classical architectures.

One of the challenges of quantum computing is to provide solutions of electronics able to control and read the Qubits at cryogenic temperature.

Oscillators is a key function of cryogenic temperature that can be found in the readout electronics or in the various reference frequency generators needed for high data-rate transmissions for example.

The postdoc will consist in designing low phase, low power and low volume oscillator using an innovative optomechanical resonator under study in LETI and to study its performances at cryogenic temperature.

The post doc will take advantage of already existing devices at LICA laboratory and on the experience of LGECA laboratory on the design of optomechanical conditioning circuits and on the characterization of cryogenic circuits.

Durée du contrat (en mois):
1 year contract renewable 1 year.

Description de l'offre:

The post doctoral position will take place in LGECA (Design of analog electronics) and LICA (design of innovative transducers) of CEA-Leti.

The architecture study goal will be to identify the oscillator topologies from the classical ones (Colpitts, Hartley, negative resistance etc.) that will be the more adequate to optomechanical resonators.

For this work, the post doc should acquire a good knowledge of optomechanical resonators in order to write an accurate electrical model that will be used in electrical simulators during oscillator optimization.

For this task, the post doc will beneficiate from the experience of the LICA laboratory.

At the end of the post doc, a demonstrator of a first cryogenic optomechanical oscillator is expected as well as a design methodology of such devices.

The post doc applicant should provide a particular attention to patenting and publishing of the main results of this research.
