Control Protocols for Entangling Gates for Group-IV Color-Centers in Diamond
Jurek Frey, Frank K. Wilhelm, Matthias M. Müller
Accurately controlling entangling gates remains a major challenge for quantum technology applications with solid-state spin qubits. Here, we study a group-IV color-center with a st…
Optimal Two-Qubit Gates for Group-IV Color-Centers in Diamond
Jurek Frey, Katharina Senkalla, Philipp J. Vetter +3
Color centers associated with group-IV dopants in diamond with long-lived nuclear spins have emerged as major candidates for distributed quantum computing nodes and quantum repeate…
Nonadiabatic corrections to fast dispersive multiqubit gates involving Z control
L. S. Theis, F. K. Wilhelm
We review a time-dependent version of the Schrieffer-Wolff transformation that accounts for real-time control of system parameters, soon to be rendered possible on a broad basis du…
Arbitrary n-Qubit State Transfer Implemented by Coherent Control and Simplest Switchable Local Noise
Ville Bergholm, F. K. Wilhelm, T. Schulte-Herbrueggen
We study reachable sets of open n-qubit quantum systems, whose coherent parts are under full unitary control, by adding as a further degree of incoherent control switchable Markovi…
Simultaneous gates in frequency-crowded multilevel systems using fast, robust, analytic control shapes
L. S. Theis, F. Motzoi, F. K. Wilhelm
We present a few-parameter ansatz for pulses to implement a broad set of simultaneous single-qubit rotations in frequency-crowded multilevel systems. Specifically, we consider a sy…
Adaptive hybrid optimal quantum control for imprecisely characterized systems
D. J. Egger, F. K. Wilhelm
Optimal quantum control theory carries a huge promise for quantum technology. Its experimental application, however, is often hindered by imprecise knowledge of the its input varia…
