2012 Nobel Prize in Physics for Measuring and Manipulating Individual Quantum Systems

Background Information and a Statement by AIP Executive Director and CEO

College Park, Md. -- The 2012 Nobel Prize in Physics will be awarded to Serge Haroche of the College de France and Ecole Normale Superieure, Paris, France; and David J. Wineland of the National Institute of Standards and Technology (NIST) and the University of Colorado, Boulder, Colo., "for ground-breaking experimental methods that enable measuring and manipulation of individual quantum systems," which have expanded our understanding of the realm of the very small and paved the way to new research and technologies.

Quantum mechanics, the study of how matter interacts with energy at the scale of atoms, has profoundly changed how scientists view the universe. On the quantum scale, matter and energy behave in ways that seem nonsensical and radically different from the world we ordinarily experience. Once exclusively in the realm of theory and thought experiments, quantum mechanics has emerged as the foundation of new scientific investigation, with intriguing possibilities for future technology and innovation. This year's laureates:

- Opened the door to experimentation and manipulation by studying individual quantum particles without destroying them;
- Measured and controlled quantum states, once beyond the reach of direct observation; and,
- Took the first steps toward harnessing quantum mechanics, which is already at work in highly accurate atomic clocks and may fulfill the promise of quantum computers that – rather than relying on zeros and ones – will use fuzzy quantum states to conduct calculations many times faster than the most powerful computers today.


"This year's Nobel Prize in Physics shines light on two ground-breaking advances in quantum physics. By measuring and manipulating both light and individual atoms, these researchers have opened the door for new investigations into the previously enigmatic and unwieldy world of quantum particles, where matter behaves in ways that are quite different from what we see in classical physics. We are beginning to harness the incredible power of quantum physics to advance technology, computers, timekeeping, cryptography, and many other innovations that have yet to be imagined."

-- Dr. H. Frederick Dylla, executive director and CEO, American Institute of Physics

"The works by Serge Haroche and David Wineland are among the most influential research endeavors of modern physics. Together they have provided new investigational tools for researchers and established a foundation to understand the relationships between matter and light at the smallest of scales. Quantum mechanics was once just theory and philosophy, but through this work and the ongoing research of others, we are now testing, manipulating, and building upon these scientific principles."

-- John Haynes, vice president, publishing, American Institute of Physics
