Description
Fast and accurate Raman spinor matterwave control is key to implementing advanced quantum technology for quantum sensing, simulation, and computation. Typical Raman controls are achieved at large single-photon detunings, not only to avoid spontaneous emissions but also for reducing the differential Stark shifts. Our work focuses on moderate single-photon detuning where the universal rotations of atomic spinors by the Raman coupling are biased by a significant Stark shift at a fixed "biased angle". We demonstrate that within this "biased rotation" regime, composite pulses can be efficiently derived with simple SU(2) dynamics for their precise implementation to alkaline atoms on a hyperfine manifold. Our scheme fills the gap between related techniques in atom interferometry and trapped-ions for stark-shift compensation, enabling ultra-precise universal Raman spin-wave control within nanoseconds with moderate laser power.
