# Experimental Implementation of Fast Quantum Searching

@article{Chuang1998ExperimentalIO, title={Experimental Implementation of Fast Quantum Searching}, author={Isaac L. Chuang and Neil A. Gershenfeld and Mark Kubinec}, journal={Physical Review Letters}, year={1998}, volume={80}, pages={3408-3411} }

Using nuclear magnetic resonance techniques with a solution of chloroform molecules we implement Grover’s search algorithm for a system with four states. By performing a tomographic reconstruction of the density matrix during the computation good agreement is seen between theory and experiment. This provides the first complete experimental demonstration of loading an initial state into a quantum computer, performing a computation requiring fewer steps than on a classical computer, and then…
