General information

Reference : UMR7010-LAULAB-003
Workplace : NICE
Date of publication : Thursday, November 05, 2020
Type of Contract : FTC Scientist
Contract Period : 12 months
Expected date of employment : 4 January 2021
Proportion of work : Full time
Remuneration : 2675,28 € (less than two years of experience)
Desired level of education : PhD
Experience required : 1 to 4 years


The candidate will have to:
➺ develop a coherent wavelength interface for converting the single photon generated by a quantum dot source emitting at 895 nm to a telecom compliant wavelength (~1560 nm). This part will be realized in a close collaboration with the C2N (Paris-Saclay, CNRS). Quandela, a company specialized single-photon-source devices based on solid-state technology, will also be involved during this project as the interface could be included in their product.
➺ develop an operational system for quantum cryptography based on converted single photons. This quantum link lies at the heart of this project, and consists in (i) frequency converting single photons out of a quantum dot, (ii) coding quantum information on the converted photons, (iii) distributing quantum information at telecom wavelength over the link in a real-field configuration, and (iv) generating secure secret cryptographic keys at high rates.


The post-doctoral work will mainly be conducted at the Institut de Physique de Nice for demonstrating the operational quantum link. The candidate will work in close collaboration with a Ph-D applicant already involved in the project.


Applicants should have :
• An excellent first degree and completed doctorate (< 2 years or close to completion) in physics.
• A strong background in quantum optics and electronics.
• The ability to perform excellent research in photonics (quantum, nonlinear, integrated)
evidenced by a strong publication record in international peer-reviewed journals.
• Ability to work in interdisciplinary projects (experiments, theory).
• Evidence of outstanding ability to work independently, and as an active collaborative
member of a research team, who is well organized and self-motivated, while working
cooperatively at all levels. Be highly motivated and have a strong commitment to research.
• Good communication skills both orally and in written English, suitable for the preparation of scientific publications in world-class journals and presentation of research at international conferences.

Work Context

Our society relies on an ever-increasing capacity to process and communicate classical bits, having important repercussions on innovations, every-day life, and global economy. As a consequence, a high-level reliance on the transmission of sensitive information over the Internet by individuals, banks, governments, and key industries, has been reached, thanks to the improvement of public cipher methods. In this framework, quantum cryptography, i.e. the first commercial quantum technology, provides a unique means to establish, at remote locations, identical random strings of secret bits, with a level of security unattainable using classical means. More specifically, this post-doc position aims at deploying a hybrid experimental platform dedicated to the development of quantum-enabled technologies and related information protocols at University of Côte d'Azur scale.
