Implementation of a three-quantum-bit search algorithm
Lieven M. K. Vandersypen, Matthias Steffen, Mark H. Sherwood +3
We report the experimental implementation of Grover's quantum search algorithm on a quantum computer with three quantum bits. The computer consists of molecules of C-labeled…
Oscillatory Exchange Coupling across CrV Alloy spacers
N. N. Lathiotakis, B. L. Gyorffy, E. Bruno +2
We have identified the pieces of the Fermi surface responsible for the long period oscillations of magnetic coupling across Cr and CrV alloy spacers in metallic multi…
Quantum Teleportation is a Universal Computational Primitive
Daniel Gottesman, Isaac L. Chuang
We present a method to create a variety of interesting gates by teleporting quantum bits through special entangled states. This allows, for instance, the construction of a quantum…
Nuclear Magnetic Resonance Quantum Computing Using Liquid Crystal Solvents
Costantino S. Yannoni, Mark H. Sherwood, Lieven M. K. Vandersypen +3
Liquid crystals offer several advantages as solvents for molecules used for nuclear magnetic resonance quantum computing (NMRQC). The dipolar coupling between nuclear spins manifes…
Quantum algorithms which accept hot qubit inputs
Xinlan Zhou, Debbie W. Leung, Isaac L. Chuang
Realistic physical implementations of quantum computers can entail tradeoffs which depart from the ideal model of quantum computation. Although these tradeoffs have allowed success…
Impurity-Induced Bound Excitations on the Surface of Bi2Sr2CaCu2O8
Ali Yazdani, C. M. Howald, C. P. Lutz +2
We have probed the effects of atomic-scale impurities on superconductivity in Bi_{2}Sr_{2}CaCu_{2}O_{8} by performing low-temperature tunneling spectroscopy measurements with a sca…
