Dr Maria Vasilopoulou presents pathway to superradiance in Cambridge

On 30 May 2025, Dr Maria Vasilopoulou, coordinator of the SUPERLASER project and researcher at NCSR Demokritos, travelled to Cambridge to deliver a lecture at the Cambridge Graphene Centre, as part of the QAMSS Strategic Research Initiative’s Advanced Technology Lecture Series. Her talk, titled “Room Temperature Superradiance in Perovskite Superlattices”, highlighted recent breakthroughs from her team that push quantum light technologies closer to practical, ambient-condition operation.

Superradiance at room temperature

In her lecture, Dr Vasilopoulou presented the phenomenon of superradiance, where many emitters act together like a single quantum dipole, producing far stronger and more coherent light than isolated emitters. Until now, such effects were largely restricted to cryogenic conditions. By engineering continuous halide perovskite nanocrystal superlattices, the SUPERLASER team demonstrated how it will be possible to achieve superradiant emission at room temperature. This breakthrough represents a major step toward the goal of the SUPERLASER project, which is to develop electrically pumped lasers based on perovskite crystal gain material, and many other applications.

Engaging with the Cambridge Community

The event drew a diverse audience from across Cambridge’s quantum, materials, and photonics communities, who engaged in lively discussions during and after the lecture. Beyond the talk itself, Dr Vasilopoulou visited research labs and met with local experts, exploring opportunities for collaboration and exchange between SUPERLASER and Cambridge groups. Her participation in the QAMSS Easter Term lecture series not only showcased SUPERLASER’s scientific leadership but also strengthened connections with one of Europe’s leading centres for advanced materials and quantum science.
