QUROPE Quantum Information Processing and Communication in Europe

Duration: 36 months

Expected start date: January 2014

 

A position for Early Stage Researchers (PhD level) is available within the Marie Curie Initial Training Network “PICQUE-Photonic Integrated Compound Quantum Encoding”  (www.picque.eu).

 

PICQUE is an European Commission funded network focused at educating Early Stage Researchers (ESRs) and Experienced Researchers (ERs) involving 10 full partners and 8 associated partners from 7 different European countries, both academic and industrial.

 

PICQUE ESRs will attend a PhD programme at the corresponding host institution. ESRs and ERs will be seconded at least once during the fellowship at another partner site and will participate to scientific schools, workshops and courses in complementary skills organized within the project (http://www.picque.eu/category/future-events/)

Objectives:

Fabrication of periodically poled LN and KTP waveguides with low propagation losses

Demonstration of fine control of phasematched frequencies and waveguide dispersion parameters for quantum state preparation

Adiabatic spatial mode conversion for intrinsic stability against misalignments

On-chip wavelength division multiplexing for spatial separation of non-degenerate pair-photons

 

Tasks and methodology:

Implementation of theoretical models for accurate prediction of device behaviour

Fabrication of integrated devices in the cleanroom facilities of UPB

Linear and nonlinear device characterization and demonstration of source characteristics in UPB’s optics labs

 

Scientific background:

Sources based on the parametric downconversion process are most established for the preparation of quantum light states. The engineering of integrated sources is key for the progress of quantum communication and information processing systems. The design and implementation of specifically tailored integrated devices for quantum applications require the combination of know-how in the fields of integrated optics, quantum optics as well as quantum information science.

 

Position Profile:

The position offers the chance of developing novel integrated devices for engineered photon pair generation based on periodically poled LN or KTP waveguides. This includes their design (including several functionalities on a single chip), the fabrication of apt structures in the clean rooms as well as their characterization in the quantum optics labs.
