Dr Wolfgang Tittel
Quantum Cryptography
Alongside iCORE's $750,000 investment, General Dynamics Canada has
committed to provide industry support to the research chair - support
that is anticipated to continue over the next five years. NSERC is
expected to provide an ICE grant of $150,000 for the initial year with
continued five year support. In addition, Dr Tittel benefits from
important support from the University of Calgary for setting up a
state-of-the-art laboratory, including a long lasting test-bed link
over the standard telecommunication fibre network. Furthermore, SAIT
will provide laboratory space to host the second end of the test-bed
link.
Research Program Overview
All data encrypted with classic cryptography techniques are
increasingly vulnerable to attacks by progressively powerful computer
systems. Quantum cryptography promises inherently secure transmission,
assuring users that no one has eavesdropped on a message. However,
current quantum technologies have shortcomings, including limited
transmission distance and slow key transmission rates.
Dr Tittel’s researches high bit-rate and long-distance quantum
cryptography technologies and the construction of the next generation
of quantum secured communications networks.
The research program aims to develop fibre-based quantum communication
systems with unprecedented key transmission rates and that can be
integrated into classical communication infrastructure and networks.
Research activity focuses in the areas of:
Quantum Cryptography Systems
Developing of high-speed, point-to-point quantum cryptographic
systems operating on widely available standard telecommunication fibres
Integration and Networks
Integrating quantum cryptographic systems with encoding algorithms for complete secure communication architectures.
Quantum Relays and Repeaters
Utilizing quantum communication schemes (e.g. entangled photons and
quantum teleportation units) for the development of a quantum relay.
Investigating the reversible transfer of quantum information between
photons and atoms for temporal storage. Quantum memory is a required
technology for a quantum repeater that can enable greater transmission
distances.
Biographical Information
Dr Tittel studied Physics at the University of Frankfurt in Germany,
was a Ph.D. student at the University of Geneva/GAP Optique
(Switzerland) and did post-doctoral at the University of Aarhus
(Denmark) and again at GAP Optique before being recruited by iCORE.
Along with collaborations with his present Quantum Memory group, who
continues on in Geneva, Dr. Tittel also brings with him existing
collaborative connections with the Institute for Quantum Computing
(Waterloo, Canada), and research groups at the Lund Institute of
Technology (Sweden), the University of Nice (France) and University of
Paderborn (Germany).
