Conventions for Quantum Pseudocode
E. Knill
A few conventions for thinking about and writing quantum pseudocode are proposed. The conventions can be used for presenting any quantum algorithm down to the lowest level and are…
Quantum Estimation of Parameters of Classical Spacetimes
T. G. Downes, J. R. van Meter, E. Knill +2
We describe a quantum limit to measurement of classical spacetimes. Specifically, we formulate a quantum Cramer-Rao lower bound for estimating the single parameter in any one-param…
A microfabricated surface-electrode ion trap for scalable quantum information processing
S. Seidelin, J. Chiaverini, R. Reichle +12
We demonstrate confinement of individual atomic ions in a radio-frequency Paul trap with a novel geometry where the electrodes are located in a single plane and the ions confined a…
Introduction to Quantum Error Correction
E. Knill, R. Laflamme, A. Ashikhmin +3
In this introduction we motivate and explain the ``decoding'' and ``subsystems'' view of quantum error correction. We explain how quantum noise in QIP can be described and classifi…
Tomography and spectroscopy as quantum computations
Cesar Miquel, Juan Pablo Paz, Marcos Saraceno +3
Determining the state of a system and measuring properties of its evolution are two of the most important tasks a physicist faces. For the first purpose one can use tomography, a m…
Quantum simulation of a three-body interaction Hamiltonian on an NMR quantum computer
C. H. Tseng, S. Somaroo, Y. Sharf +4
Extensions of average Hamiltonian theory to quantum computation permit the design of arbitrary Hamiltonians, allowing rotations throughout a large Hilbert space. In this way, the k…
