I first reported in this blog about a possible sighting of a Majorana quasi particle on Oct, 2014. In that blog post, I referred to them as gay particles because they are neither bosons nor fermions but something in between**. (I was making fun of Leon Lederman, who is credited with being the first person to refer to the Higgs boson particle as the God particle)
Check out this recent, excellent (very knowledgeable, clear and well written) article
recounting the amazing progress that has been made in the last 5 years on the gay particle front, going from an uncertain sighting of the elusive particle in 2012, to almost certain evidence of its existence just 2 weeks ago.
Most scientists believe that (gate model) quantum computing done using gay particles will have much lower error rates than quantum computing done using transmon superconductive circuits (the latter is the strategy being pursued by IBM, Google and many others).
The bad news is that Microsoft is the only major company in the world that has invested bigly in this technology and they have patented it to the hilt. The good news is that the MS quantum software is really crappy and closed source. Quantum open source will crush them like Linux and Android did before. As to the hardware, I predict that MS will try to use its patents to monopolize this technology in the US and Europe, but China will quickly duplicate the MS hardware, ignore the patents to a large extent, and offer this technology worldwide via the cloud.
**In case you are wondering, I am not gay. And the term “gay particle” is definitely not meant to be a homophobic slur. As I have said before in this blog, I have a lot of respect and admiration for many gay people, including two of mankind’s greatest heroes, Leonardo DaVinci and Alan Turing. And maybe Ettore Majorana too?
