Theory and Experiment

Our mission is to conduct interdisciplinary theoretical and experimental research into the fundamental limits to information processing. The discovery that quantum physics allows fundamentally new modes of information processing has required the existing theories of computation, information and cryptography to be superseded by their quantum generalisations. We focus on the development of quantum technologies for coherent control of individual photons and atoms and explore both the theory and the practical possibilities of constructing quantum-mechanical devices for the purpose of cryptography and computation.

Research in quantum information science in Singapore was initiated in 1998 by Kwek Leong Chuan, Lai Choy Heng, Oh Choo Hiap and Kuldip Singh as a series of informal seminars at the National University of Singapore. The seminars attracted local researchers and resulted in forming the Quantum Information Technology Group, informally referred in Singlish as "quantum lah".

In February 2002 the support from the Agency for Science, Technology and Research (A*STAR) - the Temasek Project - consolidated research efforts in the field and led to a number of faculty appointments. In 2007 the Quantum Information Technology Group was selected as the core of the first Research Centre of Excellence in quantum information science and technology. Since then, the centre has attracted a number of other researcher and continues to expand.

The Centre is funded by the Singapore National Research Foundation and the Ministry of Education. It is hosted by the National University of Singapore, but enjoys a significant autonomy both in pursuing its research goals and in governance. The Centre has its own Governing Board, a Scientific Advisory Board and is headed by Director Artur Ekert.

Understanding interacting quantum many body system and engineering and exploiting such quantum systems for quantum information purposes or quantum simulations pose some of the most outstanding challenges in quantum physics.

Furthermore, our group investigates the possibility of forming interfaces between the these many-body systems and light in order to generate novel non-classical light sources and quantum memories for light.

Our research focusses on realizing and controlling such systems using ultracold atomic or molecular quantum gases. Starting with ultracold gases of degenerate quantum matter of bosons or fermions held in optical and magnetic traps, we e.g. impose crystals of light on top of the atoms in order to trap them in controlled periodic potentials. Such arrays can serve as versatile model systems for condensed matter physics, or as useful quantum information processors and effective setups for precision atomic and molecular physics measurements.

We are on the verge of a new technological revolution as the strange and unique properties of quantum physics become relevant and exploitable in the context of information science and technology.

The Joint Quantum Institute (JQI) is pursuing that goal through the work of leading quantum scientists from the Department of Physics of the University of Maryland (UMD), the National Institute of Standards and Technology (NIST) and the Laboratory for Physical Sciences (LPS). Each institution brings to JQI major experimental and theoretical research programs that are dedicated to the goals of controlling and exploiting quantum systems.

JQI's objectives are to:

- serve as a world-class research institute, conducting fundamental investigations of coherent quantum phenomena and thereby laying the foundation for engineering and controlling complex quantum systems capable of using the coherence and entanglement of quantum mechanics;
- maintain and enhance the nation's leading role in high technology through a powerful collaboration among NIST, UMD and LPS; and
- provide a unique, interdisciplinary center for the interchange of ideas among atomic physics, condensed matter and quantum information scientists.

In pursuing these objectives, the JQI is expected to train scientists and engineers for future industrial opportunities and provide U.S. industry with cutting-edge research results.
