Organisation profile

In the Quantum Light Sources group at DTU Electro, we design, simulate and fabricate nano-devices that operate according to the rules of quantum mechanics for application in photonic quantum technologies. Our objective is to develop quantum light sources based on semiconductor quantum dots with near-unity efficiency and photon indistinguishability approaching 100%.

The quantum world offers outstanding opportunities for information and communication technology applications. Examples include, among others, the realization of new quantum computing platforms that outperform any existing super-computing system in the world. Such a powerful computer would be able to perform incredibly complex calculations, such as solving logistics problems for transportation and delivery companies and predict the correct composition of new drugs in pharmaceutical research.

In the Quantum Light Sources group, we are trying to realize the indispensable building blocks for these new quantum technologies, which require to manipulate and generate individual photon states “on demand”.

We use advanced numerical tools and quantum-mechanical techniques to accurately design the electromagnetic modes of the sources and analyze their performance. We subsequently use state-of-the-art nano-fabrication techniques combined with optical setups to fabricate and characterize efficient nanophotonic devices based on our theoretical results.

We are driven by the aim to understand the physics of quantum devices such as sources of single indistinguishable photons as well as entangled photon pairs.

UN Sustainable Development Goals

In 2015, UN member states agreed to 17 global Sustainable Development Goals (SDGs) to end poverty, protect the planet and ensure prosperity for all. Our work contributes towards the following SDG(s):

  • SDG 7 - Affordable and Clean Energy
