Potential
breakthroughs are totally revolutionary.
Quantum computers will be billions of times faster
than
todays machines.
Quantum cryptography promises perfectly secure
communications. You cannot crack this, we are
told, unlike
all the codes the world has known ever since human beings
started passing secret messages around.
When you try to eavesdrop on quantum cryptography communications in
future,
you cannot avoid being detected You have been
warned!

"For their outstanding contributions to theoretical research on
quantum coherence and its applications in quantum information
science."
Quantum Information Science is an emerging multidisciplinary field
to which numerous global projects have been devoted in recent
years, including the Quantum Information Technology (QIT)
initiative at the Faculty of Science of the National University of
Singapore.
The team has advanced the understanding of coherent quantum
phenomena and how the governing fundamental laws of physics can be
harnessed to dramatically improve the acquisition, transmission,
and processing of information.
The team's research ranges from the invention of new
methods of secure communication to the study of geometric phases in
mixed states, from trade-offs between single-particle and
multi-particle interference to entanglement detection via Bell-type
inequalities, including higher dimensional generalisation. Their
results have been published in leading journals, such as Physical
Review Letters, and the QIT theory group has become known as one of
the strongest in the field.
One highlight is the introduction of a new class of protocols for
quantum key distribution for which the security analysis is based
on the full knowledge of the properties of the quantum channel,
rather than on estimates of the transmission error rate. One of the
novel protocols is the Singapore Protocol. In contrast to other
schemes, the Singapore Protocol utilises all data for the key
generation, is 25% more efficient under ideal circumstances
than its competitor, and can be implemented even if the channel is
too noisy for the standard protocols. Together, the complete
characterisation of the channel and the key generation procedure
amount to a new paradigm in quantum cryptography.
Other highlights are an exploratory study of the possibility of
manipulating quantum systems through geometric phases, which are
robust in noisy environments, and the investigation of the
entanglement between many bodies, which is of great use for quantum
computation.
The experimental realization of these quantum coherent phenomena,
such as the implementation of secure communication and the
detection of quantum entanglement in atomic systems, is possible.
In particular, the resulting developments in secure communication
may also lead to a significant boost in industrial exploitation of
the technology.
For their outstanding contribution to theoretical research on
quantum coherence and its applications in quantum information
science, Professor Oh Choo Hiap, Professor Berthold-Georg Englert,
Associate Professor Kwek Leong Chuan and Assistant Professor
Dagomir Kaszlikowski, are awarded the National Science Award
2006.
