Using high-dimensional quantum error-avoiding code, we present two new quantum key distribution protocols over a collective noisy channel, i.e. six-photon and f
“Becoming more confident and mature, more and more domestic enterprises begin to make overseas investments and are devoting themselves to bringing their brands and products to the international market
CeOx films are deposited onto the surface of a SiO2 matrix embedded with Si nanocrystals (nc-Si/SiO2) by electron-beam evaporation of CeO2 powder in high vacuum
We study the decoherence process of an exact solvable model that consists of a central spin-1/2 coupling to the surrounding anisotropy spin-1/2 chain in transve
