ER2: Integrated quantum relay and on-demand photon-number states generation chips

Closed call – position assigned

Enrolled Fellow: Tommaso Lunghi
Start date: 1 January 2015
Supervisor: Dr Sébastien TANZILLI

Host Institution:CNRS – Laboratoire de Physique de la Matière Condensée (LPMC), CNRS UMR 7336, Université Nice Sophia Antipolis, France

Duration: 12 months
Contract: with the CNRS
Living allowances: approx. 67,900 €/year
Mobility allowances: approx. 9,700 €/year

-Exploit integrated optics for designing highly efficient devices for on-chip qbit generation and manipulation.
-Integrated quantum relay and on-demand photon-number states generation chips with optimized input-output loss of < 3 dB and a modulation regime on the order of 1 MHz so as to match deliverable of the PICQUE project.

Tasks and methodology:
-Exploit lithium niobate for modulating the refractive index at high speed through the electro-optic effect;
-Exploit LPMC proprietary “proton exchange” techniques for waveguides fabrication so as to attain low-voltage operation regime;
-Variable couplers and WDMs will be developed and integrated with several other elementary functions.

Training network
The recruited ER will be part of the ITN, which means that he/she will be granted access to the training activities of the PICQUE project.

Required skills
Working with photonic qubits involves hands on manipulation of lasers, optical systems, single-photon detection, guided-wave optics, as well as high-speed electronics. Thus, the work is experimentally very multifaceted. Besides the experimental work, a solid theoretical understanding will be necessary, and the candidate will also be expected to be able to work within a team.
