Abstract

The 2012 Nobel Prize in Physics was awarded to Serge Haroche and David J. Wineland for their groundbreaking work in developing experimental methods that measure and manipulate individual quantum systems. Their methods, which have allowed the control of a system constituted of a single atom (ion) and a single photon, have opened a wide variety of applications. As a tutorial, this article outlines the fundamental concept of their Nobel-awarded methods: cavity quantum electrodynamics.

Individual Quantum Systems The Nobel Prize in Physics for 2012 was awarded to Serge Haroche and David J. Wineland “for ground-breaking experimental methods that enable measuring and manipulation of individual quantum systems”. The former deals with photons and measures them with atoms and the latter deals with ions and manipulates them with photons. The potential and actual applications of handling quantum systems are on their way

A new epoch of quantum manipulation

Yong‐Jian Han, Zhen Wang, Guang‐Can Guo

Abstract The behavior of individual microscopic particles, such as an atom (or a photon), predicted using quantum mechanics, is dramatically different from the behavior of classical particles, such as a planet, determined using classical mechanics. How can the counter-intuitive behavior of the microscopic particle be verified and manipulated experimentally? David Wineland and Serge Haroche, who were awarded the Nobel Prize in physics in 2012, developed a set of methods to isolate the ions and photons from their environment to create a genuine quantum system. Furthermore, they also developed methods to measure and manipulate these quantum systems, which open a path not only to explore the fundamental principles of quantum mechanics, but also to develop a much faster computer: a quantum computer.

Nobel 2012: trapped ions and photons

18 What are these methods, why are they jointly recognized? The key endeavour in the last century of quantum physics has been the exploration of the coupling between matter and electromagnetic radiation. For a long time, the available experimental techniques were limited to a large number of atoms and a very large number of photons. It was only in thought experiments that one envisioned the manipulation of well-controlled individual quantum systems, dreamed of experimenting with a single atom or a single photon. For instance, Einstein and Bohr once imagined weighing a photon trapped forever in a box, covered by perfect mirrors. These gedankenexperiments and their “ridiculous consequences”, as Schrodinger once stated, played a considerable role in the genesis of quantum physics interpretation. The technical progress made these experiments possible. One can now realize some of the founding fathers' thought experiments. D. Wineland's ion traps and S. Haroche's Cavity Quantum Electrodynamics (CQED) have pioneered this domain, which is now thriving worldwide.

The Nobel Prize in physics 2012 was awarded “for ground-breaking experimental methods that enable measuring and manipulation of individual quantum systems”. The methods are based on optical technologies such as a laser, and will open a door to new quantum technologies in which light and matter interact in a qualitatively different manner.
