Experimental realization of Shor's quantum factoring algorithm using nuclear magnetic resonance

no code implementations30 Dec 2001 Lieven M. K. Vandersypen, Matthias Steffen, Gregory Breyta, Costantino S. Yannoni, Mark H. Sherwood, Isaac L. Chuang

The number of steps any classical computer requires in order to find the prime factors of an $l$-digit integer $N$ increases exponentially with $l$, at least using algorithms known at present.

Experimental Realization of an Order-Finding Algorithm with an NMR Quantum Computer

no code implementations6 Jul 2000 Lieven M. K. Vandersypen, Matthias Steffen, Gregory Breyta, Costantino S. Yannoni, Richard Cleve, Isaac L. Chuang

We report the realization of a nuclear magnetic resonance (NMR) quantum computer which combines the quantum Fourier transform (QFT) with exponentiated permutations, demonstrating a quantum algorithm for order-finding.
