Description and purpose
The project will develop simulation models and techniques that allow to model the non-linear phenomena that underpin the generation of entangled photon pairsin hollow core fibers, in order to analyze and design the prototype of the source and tune its performance. It will also develop an experimental setup to measure the performance of these fiber systems, using commercial hollow-core fibers of different specifications available on the market.

Purpose
Quantum communication technologies are reaching maturity, going from lab to applications in a few years; an optical source is needed to emit photon pairs bound by quantum entanglement, novel solutions are highly sought for viability at industrial performance and reliability ratings.
The goal of the project is the development of a platform for generation of correlated entangled photon pairs in gases, using hollow-core inhibited-coupling microstructured optical fibers.
Expected results
We envision a low-cost entangled photon source directly built out of a hollow-core fiber, so that there is high technological compatibility with the fibers proposed for high-coherence quantum state transmission and the source can be directly spliced into quantum fiber communication systems.
Achieved results
An experimental setup to measure the performance of these fiber systems, using commercial hollow-core fibers of different specifications available on the market, has been developed in the Laser Lab of the Department of Enginnering and Architecture of the University of Parma.
We have also developed a simulation model based on the Schrodinger equation to describe the four wave mixing generation in the gas-filled hollow core fiber.
