Quantum Computers: Research Into New Way of Creating Qubits With Improved Stability

I'm curious about something. Wikipedia says that a majorana fermion is a particle which is it's own anti-particle. Aside from that sounding like a contradiction in terms, it also says that no elementary particle is known to be a majorana. So who is right?

You got me there, I'm confused enough as it is in my own little quantum world!

Alternatively, it does sound like Wikipedia have contradicted themselves, or at least not adequately explained it. I guess this is why they are not considered an authoritative source of info.

My guess is that they mean oscillating fermions like neutrinos - which they mention. However as best as I can recall, they oscillate between 3 flavors, none of which is the anti-particle of any of the others.

wikipedia seems to be correct.
