| Quantum Technology: Putting Weirdness to Use |
| Speaker: | Professor Dr. Christopher Monroe (University of Maryland) |
| Abstract: | Quantum information science in the 21st century links two pillars of 20th century thought: information theory and quantum mechanics. This new field exploits the bizarre features of quantum mechanics -- uncertainty, entanglement, and measurement -- to perform tasks that are impossible using conventional means. We anticipate that exotic quantum hardware such as individual trapped atoms, quantum dots in solids, and superconducting loops of wire will not only find there way into 21st century technology, but they will also bring quantum weirdness to the forefront and stimulate new ways of thinking about foundational aspects of the physical world.

| Laser Spectroscopy of Hydrogen |
| Speaker: | The Nobel Laureate Professor Dr. Theodor W. Hänsch (Max-Planck-Institute of Quantum Optics, Garching, and Faculty of Physics, Ludwig-Maximilians-University, Munich, Germany) |
| Abstract: | The simple Balmer spectrum of atomic hydrogen has provided the Rosetta stone for deciphering the strange laws of quantum physics during during the early 20th century. Four decades ago, Doppler-free laser spectroscopy opened a new chapter in the exploration of hydrogen. Today, precision spectroscopy of hydrogen is reaching a precision of 15 decimal digits with the help of new spectroscopic tools including the laser frequency comb technique. However, the determination of fundamental constants and experimental tests of fundamental physics laws are now hindered by our insufficient knowledge of the rms charge radius of the proton. Recently, a laser measurement of the 2S-2P Lamb shift of muonic hydrogen has yielded an independent precise new value of the proton radius which differs by five old standard deviations from the official CODATA value. This discrepancy is subject of intense current discussions. It may be caused by a mistake, or it may indicate a dent in the armor of quantum electrodynamic theory. |
