Frequency stabilization of an ultraviolet laser to ions in a discharge
E. W. Streed, T. J. Weinhold, D. Kielpinski
We stabilize an ultraviolet diode laser system at 369.5 nm to the optical absorption signal from Yb+ ions in a hollow-cathode discharge lamp. The error signal for stabilization is…
Criteria for generalized macroscopic and mesoscopic quantum coherence
E. G. Cavalcanti, M. D. Reid
We consider macroscopic, mesoscopic and "S-scopic" quantum superpositions of eigenstates of an observable, and develop some signatures for their existence. We define the extent, or…
Ion-trap quantum information processing: experimental status
D. Kielpinski
Atomic ions trapped in ultra-high vacuum form an especially well-understood and useful physical system for quantum information processing. They provide excellent shielding of quant…
Robust adiabatic approach to optical spin entangling in coupled quantum dots
Erik M. Gauger, Ahsan Nazir, Simon C. Benjamin +2
Excitonic transitions offer a possible route to ultrafast optical spin manipulation in coupled nanostructures. We perform here a detailed study of the three principal exciton-media…
Non-linear dispersive regime of cavity QED: The dressed dephasing model
Maxime Boissonneault, J. M. Gambetta, Alexandre Blais
Systems in the dispersive regime of cavity quantum electrodynamics (QED) are approaching the limits of validity of the dispersive approximation. We present a model which takes into…
Teleportation fidelity as a probe of sub-Planck phase-space structure
A. J. Scott, Carlton M. Caves
We investigate the connection between sub-Planck structure in the Wigner function and the output fidelity of continuous-variable teleportation protocols. When the teleporting parti…
