Realization of quantum process tomography in NMR
Andrew M. Childs, Isaac L. Chuang, Debbie W. Leung
Quantum process tomography is a procedure by which the unknown dynamical evolution of an open quantum system can be fully experimentally characterized. We demonstrate explicitly ho…
Liquid state NMR Quantum Computing
Lieven M. K. Vandersypen, Costantino S. Yannoni, Isaac L. Chuang
This in an introduction on quantum computing and on the use of NMR to build quantum computers, geared towards an NMR audience.
NMR implementation of a building block for scalable quantum computation
D. E. Chang, L. M. K. Vandersypen, M. Steffen
We report the implementation of the central building block of the Schulman-Vazirani procedure for fully polarizing a subset of two-level quantum systems which are initially only pa…
Universal quantum computation with two-level trapped ions
Andrew M. Childs, Isaac L. Chuang
Although the initial proposal for ion trap quantum computation made use of an auxiliary internal level to perform logic between ions, this resource is not necessary in principle. I…
Universal simulation of Markovian quantum dynamics
Dave Bacon, Andrew M. Childs, Isaac L. Chuang +3
Although the conditions for performing arbitrary unitary operations to simulate the dynamics of a closed quantum system are well understood, the same is not true of the more genera…
Experimental Realization of an Order-Finding Algorithm with an NMR Quantum Computer
Lieven M. K. Vandersypen, Matthias Steffen, Gregory Breyta +3
We report the realization of a nuclear magnetic resonance (NMR) quantum computer which combines the quantum Fourier transform (QFT) with exponentiated permutations, demonstrating a…
