2012 Nobel Lectures in Physics

Kuliah Nobel Fisika 2012:

The Nobel Prize in Physics 2012 was awarded jointly to Serge Haroche and David J. Wineland

"for ground-breaking experimental methods that enable measuring and manipulation of individual quantum systems"

This is Man’s wonderful ability:
to be able to grasp the inner essence of phenomena,
not what they appear to be, but what they mean,
and the reality that we see with our eyes
is a symbol only of something higher.

What is it that our eyes see? 

It is light. Everything we see around us – colours, shapes, and objects – comes from light that strikes our eyes, which forwards the information to be analysed by our brain. What we see can be described and understood with what we today call classical physics. But if we try to describe the heart of matter, classical physics is not enough!

Prof. Serge Haroche and Prof. David J. Wineland have independently invented and developed methods for measuring and manipulating individual particles while preserving their quantum-mechanical nature, in ways that were previously thought unattainable.

The Nobel Laureates have opened the door to a new era of experimentation with quantum physics by demonstrating the direct observation of individual quantum particles without destroying them. For single particles of light or matter the laws of classical physics cease to apply and quantum physics takes over.

But single particles are not easily isolated from their surrounding environment and they lose their mysterious quantum properties as soon as they interact with the outside world. Thus many seemingly bizarre phenomena predicted by quantum physics could not be directly observed, and researchers could only carry out thought experiments that might in principle manifest these bizarre phenomena.

Through their ingenious laboratory methods Haroche and Wineland together with their research groups have managed to measure and control very fragile quantum states, which were previously thought inaccessible for direct observation.

The new methods allow them to examine, control and count the particles.
