Major Setback for Topological Computing?

Significant paper in Nature retracted








The news from the Kouwenhoven Lab is not good. What was thought to be a signal of a Majorana current turns out to be less certain. Leo Kouwenhoven (above from his website) is among the best and most well respected in the field of quantum nano science. And he is not easy to fool. So this retraction comes as a surprise and suggests that we all must be diligent.


The story is not over yet!

The Delft team along with those at UCSB, and various other groups around the world continue to make strides toward measuring this illusive signature of quantum weirdness in low dimensional materials. And though this is a setback, it is a little early to herald the demise of the topological approach. These measurements are hard to do, and we are only on the fringe of understanding how they should work anyway. It does make some sense that, for those challenging the frontier like Kouwenhoven, there will be some backtracking. We are fortunate he trains his students well (it was two former members of his team that found the mistake).

Elden Ring Players Are At A War With AFK Rune Farmers


Elden Ring has a new strategy for farming runes that focuses on getting into seemingly inaccessible parts of the map until your opponent dies or loses interest and leaves. Players who would like a classic PvP fight are discovering new ways to fight back. The results are fun and shocking, but will they be enough to Elden Ring Runes stem the tide of Elden Ring's latest exploit?


There are few things gamers enjoy more than not playing, but still being rewarded for it. AFK farms are very popular and Elden Ring, it turns out, is not exempt from. There are a lot of players who have been nabbed into…
