Plasmonic Enhancement of Fluorescence and Protein Dynamics in Living Mammalian Cells

Advanced Materials, EarlyView.
This study demonstrates plasmonic enhancement of the function of fluorescent voltage sensing proteins (genetically encoded voltage indicators, (GEVIs), QuasAr6) in live mammalian cells. Coupling to plasmonic nanoparticles does not just increase fluorescence, but influences the protein photocycle, creating a hybrid sensor with its response speed to ...

Exact and efficient simulation of concordant computation

New Journal of Physics, 2015
Concordant computation is a circuit-based model of quantum computation for mixed states, that assumes that all correlations within the register are discord-free (i.e. the correlations are essentially classical) at every step of the computation.

AN IMPROVED QUANTUM SCHEDULING ALGORITHM [PDF]

International Journal of Foundations of Computer Science, 2003
The scheduling problem consists of finding a common 1 in two remotely located N bit strings. Denote the number of 1s in the string with the fewer 1s by ∊N. Classically, it needs Ω(∊N log 2 N) bits of communication to find the common 1. The best known quantum algorithms require about [Formula: see text] qubits of communication.
