Taller: Quantum computers and Schrödinger’s cat

(Spanish: Las Computadoras Cuánticas y El Gato de Schrödinger)

Sede: Aula D ubicada en el Segundo piso de CEVIDE.

As the size of computer logic gates and memory elements approaches the atomic scale, we are forced to deal with the constraints imposed by the laws of quantum mechanics. However, we now also know that a computer based on quantum mechanics could solve certain problems that are intractable on conventional computers. Interestingly, if this device could be made on a large scale it would have the same characteristics as Erwin Schrödinger’s famous 1935 hypothetical cat that could be both dead and alive at the same time. I will briefly relate how our group at NIST became involved in these topics through our experiments on atomic ions, but these only serve as examples of similar work being performed in many other laboratories around the world.

With the availability of spectrally pure lasers and the ability to precisely measure optical frequencies, it appears the era of optical atomic clocks has begun. In one clock project at NIST we have used single trapped atomic ions because uncertainties in systematic effects are smallest, reaching a fractional error of Δf/f0 = 0.8 x 10-17. At this level, many interesting effects, including those due to special and general relativity, must be calibrated and corrected for.
