Quantum mechanics once baffled scientists. Now it's changing the world

Quantum mechanics has evolved from a theoretical puzzle in the early 20th century into the foundation for modern technologies like lasers and microchips. Dr. Marlan Scully highlights how these once-bizarre concepts are now driving innovations in quantum computing and secure communications.
Why it matters
Quantum technology is expected to revolutionize computing, energy efficiency, and data security, representing the next frontier of scientific advancement.
For much of the early 20th century, quantum mechanics was one of the most puzzling ideas in science. The theory challenged conventional thinking and left even leading physicists struggling to make sense of its implications. A century later, it has become the foundation of technologies that influence daily life, including lasers, microchips, secure communications, and emerging quantum computers.
