Dynamically corrected gates from geometric space curves
Edwin Barnes, Fernando A. Calderon-Vargas, Wenzheng Dong +3
Quantum information technologies demand highly accurate control over quantum systems. Achieving this requires control techniques that perform well despite the presence of decoherin…
Designing arbitrary single-axis rotations robust against perpendicular time-dependent noise
Bikun Li, F. A. Calderon-Vargas, Junkai Zeng +1
Low-frequency time-dependent noise is one of the main obstacles on the road towards a fully scalable quantum computer. The majority of solid-state qubit platforms, from superconduc…
Geometric formalism for constructing arbitrary single-qubit dynamically corrected gates
Junkai Zeng, C. H. Yang, A. S. Dzurak +1
Implementing high-fidelity quantum control and reducing the effect of the coupling between a quantum system and its environment is a major challenge in developing quantum informati…
The fastest pulses that implement dynamically corrected gates
Junkai Zeng, Edwin Barnes
Dynamically correcting for unwanted interactions between a quantum system and its environment is vital to achieving the high-fidelity quantum control necessary for a broad range of…
