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…

Discrete time crystal in the gradient field Heisenberg model
Bikun Li, John S. Van Dyke, Ada Warren +2
We show that time crystal phases, which are known to exist for disorder-based many-body localized systems, also appear in systems where localization is due to strong magnetic field…
