The Nobel Prize in Physics David Wineland in UAEH

Nobel Prize in Physics 2012, yesterday received the investiture as New Honorary Visiting Professor at the Universidad Autónoma del Estado de Hidalgo, in a ceremony led by the rector Humberto Veras Godoy.

The Nobel Prize for her work innovative experimental methods that enable measuring and manipulation of individual quantum systems, presented to the university community Keynote: Quantum computers and Schrödinger’s cat.

The American physicist, who serves on the National Institute of Standards and Technology and University of Colorado at Boulder, is recognized for his work on advances in optics, laser cooling of ions in traps Paul and using trapped ions quantum computing operations.

Member of the National Academy of Science since l992, maintains its focus area in Atomic Physics, Wineland explained how he and the Moroccan scientific Serge Laroche developed innovative methods to measure and manipulate particles and thus open the door to a new era in the experiments in quantum physics research that creditors did win the Nobel Prize.

Wineland referred to the design of traps ions (atomic nuclei) by electromagnetic fields, which photons are added and have the ability to manipulate quantum systems with high precision that provide insight into the behavior of particles at the quantum level.

Some of the applications include high-precision atomic clocks, widely used today in navigation, as well as the development of electronic devices that promise to revolutionize the world, perhaps in the same way you did the laser.

The work of Haroche and Wineland are also considered as pioneers in the development of dreamed quantum computer, a computer would much computing power, speed and storage you will see our current technology in its infancy.

He explained that in his research argue that according to the Theory of Relativity Albert Einstein time is affected by motion and gravity, the higher the speed and more intense gravity, the slower over time.

“Navigating the Global Positioning System accuracy depends on the reception of satellite signals whose watches have been carefully calibrated, considering that gravity is somewhat weaker several hundred kilometers above the Earth’s surface and an optical clock is possible to measure the variation of time when the speed varies less than 10 meters per second, or when gravity is altered as a result of a difference in height of only 30 centimeters. ”

Wineland currently works with the team in using NIST ions found in a trap to build a hundred times more accurate clock cesium atomic clocks that are currently the standard for measuring time.

“The cesium clocks operating in the microwave range while ions watches use visible light, hence its name: optical clocks, so this device can consist of one or two ions in a trap, of these, one is used as a clock and the other is used to read the clock without altering its quantum state, causing its destruction. “
