  Theoretical Quantum Information Processing (QIP) has matured from the use of
qubits to the use of qudits (systems having states> 2). Where as most of the
experimental implementations have been performed using qubits, little
experimental work has been carried out using qudits as yet. In this paper we
demonstrate experimental realization of a qutrit system by nuclear magnetic
resonance (NMR), utilizing deuterium (spin-1) nuclei partially oriented in
liquid crystalline phase. Preparation of pseudopure states and implementation
of unitary operations are demonstrated in this single-qutrit system, using
transition selective pulses.
