SBQMI Family & Friends: The spooky dual nature of light

Virtual event

The wave-particle duality of light (or other quantum objects), where the photon (quanta of light) must be seen as in the form of wave as well as particle, has been generally accepted not one century ago. This quantum mechanical concept is already strange enough to us because there is no analogy of it in our daily classical world. Over time physicists have designed experiments to explore the quantum-ness of light further and have discovered more and more counter-intuitive spooky actions of light. In this presentation, PhD student Xiruo Yan will introduce some of the “mind boggling” results of the quantum optical experiments and how we can make use of them.

Unboxing Quantum: Seeing the World in a Different Light

Virtual event

Everyday, the interaction between light and matter is giving us information about the world that we live in through our eyes. But the range of frequencies that our eyes are sensitive to -- visible light -- is extremely limited. How does light interact with matter on other frequencies? And how can we leverage light-matter interaction […]

Unboxing Quantum: Spooky Action

Virtual event

Spooky Action at a Distance Quantum Entanglement and Spooky Action won the Nobel Prize in physics this year. Once considered a boogieman in physicists' closets, quantum entanglement is one of the weirdest, most unintuitive phenomena in the natural world. Dubbed “spooky action at a distance” by Einstein himself, this quantum behavior puzzled scientists for years […]
