Improved DAC driving scheme for OFDM applications [PDF]

open access: yes, 2010
Presented is a 'Redundant Signed Digit' driving scheme for binary weighted D/A conversion. This scheme retains the simplicity of conventional binary weighted D/A conversion, but has greatly improved robustness with regard to parasitic effects, especially

Robust Trapped-Ion Quantum Logic Gates by Continuous Dynamical Decoupling [PDF]

open access: yes, 2012
We introduce a novel scheme that combines phonon-mediated quantum logic gates in trapped ions with the benefits of continuous dynamical decoupling. We demonstrate theoretically that a strong driving of the qubit decouples it from external magnetic-field ...

Addressing individual atoms in optical lattices with standing-wave driving fields [PDF]

open access: yes, 2007
A scheme for addressing individual atoms in one- or two-dimensional optical lattices loaded with one atom per site is proposed. The scheme is based on position-dependent atomic population transfer induced by several standing-wave driving fields.
