Purpose and goal
This step-2 project establishes a strategic collaboration between Linköping University (LiU), Sweden, and Nanyang Technological University (NTU), Singapore. The primary objective is to explore room-temperature single-photon emitters (SPEs) operating at the telecom wavelengths based on cubic silicon carbide (3C-SiC). These telecom SPEs are essential for quantum communication, enabling secure, long-distance fiber-optic data transmission with minimal loss.
Expected effects and result
The main expected outcome of this project is to achieve bright, stable, room-temperature single-photon emitters (SPEs) operating at the telecom wavelengths for quantum communication. This project will also strengthen the Sweden-Singapore research network, fostering innovation in quantum technologies and aligning with global goals for sustainable development and digital security.
Planned approach and implementation
This project will be carried out through close collaboration between Linköping University (LiU), Sweden, and Nanyang Technological University (NTU), Singapore. It combines LiU’s expertise in 3C-SiC growth and defect engineering with NTU’s internationally recognized strengths in single-photon emitters and quantum photonics. Regular virtual meetings, results discussions, and exchange visits will ensure effective data sharing and joint decision-making.
