    "abstract": "Theoretical Quantum Information Processing (QIP) has matured from the use of\nqubits to the use of qudits (systems having states\u003e 2). Where as most of the\nexperimental implementations have been performed using qubits, little\nexperimental work has been carried out using qudits as yet. In this paper we\ndemonstrate experimental realization of a qutrit system by nuclear magnetic\nresonance (NMR), utilizing deuterium (spin-1) nuclei partially oriented in\nliquid crystalline phase. Preparation of pseudopure states and implementation\nof unitary operations are demonstrated in this single-qutrit system, using\ntransition selective pulses.",
