- wolfgke 7y agoThe Wikipedia article has a short paragraph on this: https://en.wikipedia.org/w/index.php?title=Majorana_fermion&oldid=949209707#Majorana_bound_states_in_quantum_error_correction https://en.wikipedia.org/w/index.php?title=Majorana_fermion&...
- DrAwdeOccarim 7y agoThanks. I read it and I guess the answer to my question is above my pay grade...
- spacetracks 7y agoQubits are susceptible to all kinds of environmental noise. That's why current designs are cooled to cryogenic temperatures. Certain kinds of Majorana particles solve this problem by making the qubit distributed. In a handwaving way, the 1 state of the qubit is on one end of a wire, and the zero state is on the other; really there is a Majorana particle on each end of the wire, and by manipulating them you can control the state of the qubit. To manipulate the qubit you must interact with both ends of the wire at the same time. That goes for noise as well. And noise typically acts locally, not in two places at the same time, so the qubit is protected.
- DrAwdeOccarim 7y agoVery cool. Thank you for that! Is there an easy way to explain why you can't do this with other particles but you can with Majorana particles?
