How The Majorana Fermion Is Going To Change The World

Posted by in categories: computing, education, particle physics, quantum physics

We now have a way to do tracibility in QC.


Chinese scientists won a major victory recently, by proving that the Majorana fermion — a particle we’ve found tantalizing hints of for years — genuinely exists. This discovery has huge implications for quantum computing, and it might change the world. But how?

A Majorana fermion is weird even by the standards of quantum physics. If you remember your high school physics, you remember that atomic particles like protons and electrons have a charge, positive or negative. The Majorana fermion, however, doesn’t have a charge, which allows it to be matter and anti-matter at the same time. Yes, that is incredibly confusing, even to quantum physicists, and they’re still arguing over how that even works.
