TITLE: Perspectives in NMR Quantum Computing: Decompositions of the QFT using selective pulses

DATE & DAY: 31 January 2008, Thursday
VENUE: Seminar Hall
TIME: 4.00 P.M.

NMR quantum information processors are the most  successful prototypes of quantum computers today, and liquid
state NMR quantum computers have been able to implement Shor's quantum factoring algorithm on 7 qubits and to demonstrate quantum
control methods on 12 qubits. However, much needs to be done before an NMR quantum computer that goes much beyond
proof-of-principle is built. In particular, the DiVincenzo criteria of initialization, read-out and decoherence mitigation
need to be seriously addressed. The Quantum Fourier transform (QFT) is a key ingredient in most quantum algorithms and much experimental
research is focused on constructing efficient decompositions of the QFT from the point of view of actual time-costs and accuracy of the
implementation. This talk will describe the state-of-the-art in NMR quantum computing and discuss efficient selective pulse decompositions
of the QFT.

Tea shall served at 3.45 P.M.
All interested are invited to attend
