Numerical study of three-body recombination for systems with many bound states
Jia Wang, J. P. D'Incao, Chris H. Greene
Three-body recombination processes are treated numerically for a system of three identical bosons. The two-body model potentials utilized support many bound states, a major leap in…
Asymptotically optimal data analysis for rejecting local realism
Yanbao Zhang, Scott Glancy, Emanuel Knill
Reliable experimental demonstrations of violations of local realism are highly desirable for fundamental tests of quantum mechanics. One can quantify the violation witnessed by an…
Improving Quantum Clocks via Semidefinite Programming
Michael Mullan, Emanuel Knill
The accuracies of modern quantum logic clocks have surpassed those of standard atomic fountain clocks. These clocks also provide a greater degree of control, because before and aft…
Extreme non-linear response of ultra-narrow optical transitions in cavity QED for laser stabilization
M. J. Martin, D. Meiser, J. W. Thomsen +2
We explore the potential of direct spectroscopy of ultra-narrow optical transitions of atoms localized in an optical cavity. In contrast to stabilization against a reference cavity…
Sideband Cooling Micromechanical Motion to the Quantum Ground State
J. D. Teufel, T. Donner, Dale Li +7
The advent of laser cooling techniques revolutionized the study of many atomic-scale systems. This has fueled progress towards quantum computers by preparing trapped ions in their…
Conditional Spin-Squeezing of a Large Ensemble via the Vacuum Rabi Splitting
Zilong Chen, Justin G. Bohnet, Shannon R. Sankar +2
We use the vacuum Rabi splitting to perform quantum nondemolition (QND) measurements that prepare a conditionally spin-squeezed state of a collective atomic psuedo-spin. We infer a…
