Heisenberg scaling of imaging resolution by coherent enhancement
Robert McConnell, Guang Hao Low, Theodore J. Yoder +4
Classical imaging works by scattering photons from an object to be imaged, and achieves resolution scaling as , with the imaging time. By contrast, the laws of quan…
Iterative Precision Measurement of Branching Ratios Applied to 5P states in 88Sr+
Helena Zhang, Michael Gutierrez, Guang Hao Low +4
We report on a method for measuring the branching ratios of dipole transitions of trapped atomic ions by performing nested sequences of population inversions. This scheme is broadl…
Effects of electrode surface roughness on motional heating of trapped ions
Kuan-Yu Lin, Guang Hao Low, Issac L. Chuang
Electric field noise is a major source of motional heating in trapped ion quantum computation. While the influence of trap electrode geometries on electric field noise has been stu…
