Implementation of a quantum algorithm on a nuclear magnetic resonance quantum computer by Jones, J, Mosca, M

Preparing high purity initial states for nuclear magnetic resonance quantum computing. by Anwar, MS, Blazina, D, Carteret, H, Duckett, S, Halstead, T, Jones, J, Kozak, C, Taylor, R

“…Here we demonstrate how parahydrogen can be used to prepare a two-spin system in an almost pure state which is suitable for implementing nuclear magnetic resonance quantum computation. A 12 ns laser pulse is used to initiate a chemical reaction involving pure parahydrogen (the nuclear spin singlet of H2). …”

Resonance offset tailored composite pulses. by Cummins, H, Jones, J

“…We describe novel composite pulse sequences which act as general rotors and thus are particularly suitable for nuclear magnetic resonance quantum computation. The resonance offset tailoring to enhance nutations approach permits perfect compensation of off-resonance errors at two selected frequencies placed symmetrically around the frequency of the radiofrequency source.…”

Implementing quantum logic gates with gradient ascent pulse engineering: principles and practicalities. by Rowland, B, Jones, J

“…We briefly describe the use of gradient ascent pulse engineering (GRAPE) pulses to implement quantum logic gates in nuclear magnetic resonance quantum computers, and discuss a range of simple extensions to the core technique. …”

Witnesses of non-classicality for simulated hybrid quantum systems by Jones, JA, Bhole, G, Marletto, C, Vedral, V

“…Here we illustrate some of the subtleties of the argument, to do with the role of locality of interactions and of non-classicality, and perform proof-of-principle experiments illustrating the logic of the proposals, using a Nuclear Magnetic Resonance quantum computational platform with four qubits.…”
