Journal ArticleDOI
Sub-Riemannian geometry and time optimal control of three spin systems: Quantum gates and coherence transfer
TL;DR: In this article, the authors provide time-optimal pulse sequences for producing an important class of effective Hamiltonians in three-spin networks, which are useful for coherence transfer experiments in NMR, involving a network of coupled spins, using temporary spin decoupling.
Journal ArticleDOI
Exploring the limits of broadband excitation and inversion pulses.
TL;DR: A systematic study of rf-limited broadband excitation by optimized pulses and broadband inversion by optimization pulses with respect to bandwidth and B(1)-field is presented.
Journal ArticleDOI
Unitary Control in Quantum Ensembles: Maximizing Signal Intensity in Coherent Spectroscopy
Steffen J. Glaser,Thomas Schulte-Herbrüggen,M. Sieveking,O. Schedletzky,Niels Chr. Nielsen,Ole W. Sørensen,Christian Griesinger +6 more
TL;DR: A gradient-based systematic procedure for optimizing these transformations is described that finds the largest projection of a transformed initial operator onto the target operator and, thus, the maximum spectroscopic signal.
Journal ArticleDOI
Cartan decomposition of SU(2n) and control of spin systems
Navin Khaneja,Steffen J. Glaser +1 more
TL;DR: In this paper, an explicit parameterization of any arbitrary unitary transformation on n qubits, in terms of one qubit and two qubit operations, was given, based on the Cartan decomposition of the semi-simple Lie group SU(2n).
Journal ArticleDOI
Optimal control in NMR spectroscopy: Numerical implementation in SIMPSON
Zdeněk Tošner,Zdeněk Tošner,Thomas Vosegaard,Cindie Kehlet,Navin Khaneja,Steffen J. Glaser,Niels Chr. Nielsen +6 more
TL;DR: The implementation of optimal control into the open source simulation package SIMPSON is presented for development and optimization of nuclear magnetic resonance experiments for a wide range of applications, including liquid- and solid-state NMR, magnetic resonance imaging, quantum computation, and combinations between NMR and other spectroscopies.
