Abstract

One of the essential requirements for Quantum Information Processing (QIP) is implementing universal sets of gates with high fidelity. All quantum operations can be decomposed and approximated with a combination of elements in a universal set of gates with arbitrary precision. Nuclear Magnetic Resonance (NMR) is one of the techniques that has attracted a lot of attention for testing quantum algorithms. In this article, the first implementation of a universal set of quantum gates with NMR in Iran is reported. Specifically, we used the hydrogen (1H) and carbon (13C) nuclear spins in chloroform as the quantum bits and implemented single and two-qubit gates on them. The quality of these gates was evaluated using quantum tomography. Experimental results show that the gates were implemented with fidelities of more than %90. This work could pave the way for experimental realization of quantum algorithms for applications in Quantum Computing, Quantum Sensing and Quantum Simulations.
