Experimental Implementation of a Concatenated Quantum Error-Correcting Code
Nicolas Boulant, Lorenza Viola, Evan M. Fortunato +1
Concatenated coding provides a general strategy to achieve the desired level of noise protection in quantum information storage and transmission. We report the implementation of a…
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…
A Method for Modeling Decoherence on a Quantum Information Processor
G. Teklemariam, E. M. Fortunato, C. C. Lopez +4
We develop and implement a method for modeling decoherence processes on an N-dimensional quantum system that requires only an -dimensional quantum environment and random class…
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…
