How to Stop Light in Its Tracks

The video explores the concept of light speed, highlighting its constancy in a vacuum and variations in different mediums. It delves into the groundbreaking ability to slow and even freeze light using electromagnetically induced transparency, a phenomenon first observed in 1991. The process involves using lasers to manipulate energy levels in atoms, creating a 'dark state' where light can pass through a previously opaque medium. This technology has potential applications in quantum computing and cryptography, offering a way to store complex quantum information. Despite challenges, advancements like IBM's chip show promise for future developments.
