有谁听说过 NV DIAMOND吗？

DeadCow

据说nv diamond在很多教育机构掀起热潮，请问有谁知道是什么吗？我听letcurer讲是diamond的一种，但我不大清楚是什么。。

知道或有相关资料的，可以讲下吗？

我是否有写错？因为我听不清楚letcurer讲的，她只是带过。。

什么来的？？
我也很有兴趣知道

好像是跟Quantum Computing有关？？

DeadCow

quantum computing又是什么来的？

有相关资料吗？谢谢

Quantum Computing是一种突破现今电脑的东东。。。不再是10101011001这些数字。。所以运行速度可以更快、处理更多资料！

[size=-1]In solid-state physics, an impurity spot in crystal is called a color center. (color just mean optical, nothing to do with colors). This center is either a vancancy (empty) or filled with single atom impurity. Nitrogen vacancy (NV) center is a center with one nitrogen atom missing. In natural (not pure) diamonds, there are lots of these kinda impurities, they r called Nitrogen vacancy (NV) center diamond. These defects gives a promosing stable light source for SEMs microscopy.

When a laser shines into it, each defect spots are excited to a unique excitation states. This excitation affects the spinning of the electrons around the center.NV diaomond gives stable spins and correlation between each centers.

In QC, a single bit is called a qubit. One qubit can have 3 states (1,0 or 1/2 state)
A promising medium for one qubit is the spin state. (up, down or and correlation between the 2 states). The problem of QC is to achieve a stable correlation state (ie. a stable 1/2). NV diamond's centers produce a stable correlation state between each centers.

你也是读物理的？
