Dynamical Control of Quantum Coherence for Current and Future Information Technologies

Dynamical Control of Quantum Coherence for Current and Future Information Technologies

This ASI allows scientists in Hong Kong and the region to learn about exciting developments of dynamical quantum control.
  • 4 January — 8 January 2012

Key topics

While the microelectronics-based information technology is approaching the fundamental limit on the transistor size, the quantum effects in nanostructures will change the way of information acquisition and processing. Nanometrology and quantum computing are two paradigmatic subfields of the new quantum information technologies. Dynamical control of quantum coherence, being the key for realistic implementation of quantum computing, has been rapidly advanced in recent five years. Thanks to these advances, initialization, control, and detection of quantum coherence of single quantum objects, in particular, single spins in solids, have become feasible. Control of spin coherence has been the basis of nuclear magnetic resonance spectroscopy and magnetic resonance imaging, which have vast applications in chemical and biological analysis, material characterization, medical diagnosis, etc. Advanced techniques in magnetic resonance spectroscopy are a corner stone of quantum computing. in return, the quantum coherence control, with unprecedented precision and sensitivity, is rejuvenating the magnetometry. This ASI serves as a timely platform to expose the scientists in Hong Kong and the region to the exciting developments of dynamical quantum control. The new information technologies based on quantum coherence control involve advanced methods in materials sciences, nanotechnologies, computational physics, and quantum sciences. The proposed ASI will provide a gold opportunity to consolidate the local research excellence in these fields to play a world-leading role in fostering the new information technologies.
