The Nobel Prize in Chemistry 2023 - Quantum dots

Moungi G. Bawendi, Louis E. Brus and Alexei I. Ekimov were awarded the Nobel Prize in Chemistry 2023 for the discovery and development of quantum dots. These tiny quantum systems have unique properties and many applications: they emit light used in television screens and LED lamps, they catalyse chemical reactions, and their emission marks the borders of tumor tissue for a surgeon. Ana Predojević, is associate professor at Fysikum: "We use the best tools and methods available to modern science to generate quantum light, harness its unique properties, and bring it closer to real-world application."

Quantum mechanics predicts effects that are counter-intuitive

Quantum mechanics predicts effects that are counter-intuitive and impossible to reconcile with our daily experience. One of the most intriguing examples of these predictions is that a pair of particles can be entangled. When two particles are entangled we cannot describe the properties of one of them without referring to the other, they behave as a single entity.

Entangled photons are a key enabler of quantum technology

Extremely efficient entangled photon pair sources can be achieved by employing a simple but effective approach – placing quantum dots in broadband pillar microcavities. Professor Ana Predojevic, member of Quantum Photonics group at Fysikum, tells us more.
