Quantum Mechanics and Quantum Physics

In the words of Niels Bohr "anybody who thinks they understand quantum physics is wrong." Quantum mechanics describes how the very small particles like electrons and atoms behave in ways contrary to most intuition. Discover the weirdness of quantum mechanics and how it is changing the way we make computers and secret codes through quantum computing and cryptography. Learn about the Heisenberg Uncertainty Principle and how it constrains how much we can know about a particle.

The 2005 Nobel Prize in Physics

The 2005 Nobel Prize in Physics is devoted to optics, with half of the prize going to Roy J. Glauber of Harvard University for his quantum theory of optical coherence, and one-quarter each going to John L. Hall and Theodor W. Hänsch, for their development of ultra-high-precision measurements of light.

1927 Solvay Conference Film
One of the most famous photos in the history of physics captures the illustrious participants at the fifth Solvay Conference in Brussels, October 1927. 29 physicists, the main quantum theorists of the day, came together, 17 of the 29 attendees were or became Nobel Prize winners. This is a home movie shot by Irving Langmuir, (1932 Nobel Prize winner). Twenty-one of the 29 attendees are on the film. The film includes shots of Erwin Schrödinger, Albert Einstein, Marie Curie, Dirac and Niels Bohr.

The Quantum Computer
By exploiting the unusual properties of Quantum Physics, physicists hope to make a computer that is, in many ways, better and faster than any computer that can ever possibly be built using the techniques of “classical” electronics.
