Tailoring of Energy Band in Electron-Blocking Structure Enhancing the Efficiency of AlGaN-Based Deep Ultraviolet Light-Emitting Diodes

open access: yesIEEE Photonics Journal, 2016
Electron-leakage is a deep-rooted problem for nitride-based light-emitting diodes (LEDs), particularly for AlGaN-based deep-ultraviolet (DUV) LEDs. In this paper, a specific design for the electron-blocking structure in AlGaN DUV LEDs, increasing the Al ...

Efficient distributed quantum computing [PDF]

open access: yesProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2013
We provide algorithms for efficiently moving and addressing quantum memory in parallel. These imply that the standard circuit model can be simulated with a low overhead by a more realistic model of a distributed quantum computer. As a result, the circuit model can be used by algorithm designers without worrying whether the underlying architecture ...

Efficient quantum walk on a quantum processor [PDF]

open access: yesNature Communications, 2016
AbstractThe random walk formalism is used across a wide range of applications, from modelling share prices to predicting population genetics. Likewise, quantum walks have shown much potential as a framework for developing new quantum algorithms. Here we present explicit efficient quantum circuits for implementing continuous-time quantum walks on the ...

Efficiency droop in InGaN/GaN multiple quantum well light-emitting diodes with nonuniform current spreading [PDF]

open access: yes, 2011
We demonstrate that the efficiency droop phenomenon in multiple quantum well InGaN/GaN light-emitting diodes (LEDs) may be connected to the current crowding effect.

Efficient Universal Blind Quantum Computation [PDF]

open access: yesPhysical Review Letters, 2013
We give a cheat sensitive protocol for blind universal quantum computation that is efficient in terms of computational and communication resources: it allows one party to perform an arbitrary computation on a second party's quantum computer without revealing either which computation is performed, or its input and output. The first party's computational

Spatial-Related Community Structure and Dynamics in Phytoplankton of the Ross Sea, Antarctica

open access: yesFrontiers in Marine Science, 2020
The Ross Sea exhibits the largest continental shelf and it is considered to be the most productive region in Antarctica, with phytoplankton communities that have so far been considered to be driven by the seasonal dynamics of the polynya, producing the ...

QE evolution of bialkali photocathode at cryogenic temperature

open access: yesFrontiers in Physics, 2023
Photocathode plays an important role in generating high brightness and low emittance electron beam and K-Cs-Sb photocathode is preferred in SRF injectors for its high quantum efficiency, long lifetime, and low thermal emittance.
