Area of Research
Muhamed Sewidan, Research Assistant at The Institute of Photonics, is conducting research centred on quantum photonic technology, with a particular emphasis on developing a cutting-edge, integrated quantum light source. The project aims to bolster the security and efficiency of quantum communication networks.
Quantum encryption is becoming increasingly essential in the modern digital world due to the growing number of cyber threats. Traditional encryption techniques, which rely on complex mathematical algorithms, are at risk of being broken by powerful quantum computers in the near future. Quantum encryption, particularly through quantum key distribution (QKD), offers a fundamentally secure method of communication by leveraging the principles of quantum mechanics.
The team at the Leibniz University of Hannover aims to build an integrated and efficient quantum light source designed to be implemented in future QKD networks.
The Use of Covesion PPLN Technology
To support their research, Muhamed recently acquired a 30mm MgO:PPLN waveguide from Covesion, selected specifically to maximize conversion efficiency. The waveguide plays a pivotal role in their project by providing a high-rate photon pair source via Spontaneous Parametric Down Conversion (SPDC), essential for the development of QKD quantum networks.
The team are currently evaluating the waveguides temporal and spectral correlations to compare it with their own fabricated components and to assess its potential for future integration into their quantum light source as their aim is to produce a packaged quantum light source, containing the waveguide, which has the potential to be embedded in QKD quantum networks in the future.
Why Covesion?
Muhamed’s decision to select Covesion’s product was influenced by their previous positive experiences with Covesion’s offerings and the suitability of the products for their current needs. Covesion’s reputation for high quality components aligned perfectly with the project requirements.
“We wanted to commend the outstanding customer service provided by Lewis Smith from Covesion. His expertise and support were invaluable throughout our engagement. Lewis addressed all our queries with patience and clarity, demonstrating a high level of professionalism and dedication. His commitment to ensuring a positive customer experience was evident, and we are extremely satisfied with the service provided. We would highly recommend Covesion’s customer service team to others for their exceptional support.”
