Optically driven silicon-based quantum gates with potential for high-temperature operation [PDF]

, 2003
We propose a new approach to constructing gates for quantum information processing, exploiting the proper-ties of impurities in silicon. Quantum information, embodied in electron spins bound to deep donors, is coupled via optically induced electronic ...

Using the Palladium as core and Platinum as shell for ORR [PDF]

Hydrogen, Fuel Cell & Energy Storage, 2014
In this work, electrocatalyst with core-shell structure (Pd as core and Pt as shell on VulcanXC-72R) was synthesis. Not only this structure can reduce the amount of platinum but it also can increase the gas diffusion electrode (GDE) performance in ...
