Robust Control of Quantum Information
Marco A. Pravia, Nicolas Boulant, Joseph Emerson +4
Errors in the control of quantum systems may be classified as unitary, decoherent and incoherent. Unitary errors are systematic, and result in a density matrix that differs from th…
Experimental Demonstration of Quantum Lattice Gas Computation
Marco A. Pravia, Zhiying Chen, Jeffrey Yepez +1
We report an ensemble nuclear magnetic resonance (NMR) implementation of a quantum lattice gas algorithm for the diffusion equation. The algorithm employs an array of quantum infor…
A Robust Method for Estimating the Lindblad Operators of a Dissipative Quantum Process from Measurements of the Density Operator at Multiple Time Points
N. Boulant, T. F. Havel, M. A. Pravia +1
We present a robust method for quantum process tomography, which yields a set of Lindblad operators that optimally fit the measured density operators at a sequence of time points.…
Exploring Noiseless Subsystems via Nuclear Magnetic Resonance
Evan M. Fortunato, Lorenza Viola, Marco A. Pravia +4
Noiseless subsystems offer a general and efficient method for protecting quantum information in the presence of noise that has symmetry properties. A paradigmatic class of error mo…
Introduction to NMR Quantum Information Processing
R. Laflamme, E. Knill, D. G. Cory +11
After a general introduction to nuclear magnetic resonance (NMR), we give the basics of implementing quantum algorithms. We describe how qubits are realized and controlled with RF…
Design of Strongly Modulating Pulses to Implement Precise Effective Hamiltonians for Quantum Information Processing
Evan M. Fortunato, Marco A. Pravia, Nicolas Boulant +3
We describe a method for improving coherent control through the use of detailed knowledge of the system's Hamiltonian. Precise unitary transformations were obtained by strongly mod…
