In particle physics a Majorana fermion (/ maɪəˈrɑːnə / [1]) or Majorana particle is a fermion that is its own antiparticle. They were hypothesised by Ettore Majorana in 1937. The term is sometimes used in opposition to Dirac fermion, which describes fermions that are not their own antiparticles.

Ettore Majorana (/ m aɪ ə ˈ r ɑː n ə /, [2] Italian: [ˈɛttore majoˈraːna]; born 5 August 1906 and disappeared 1938) was an Italian theoretical physicist who worked on neutrino masses. On 25 March 1938, he disappeared under mysterious circumstances after purchasing a ticket to travel by ship from Naples to Palermo.

3 days ago · When cooled to near absolute zero and tuned with magnetic fields, these devices form topological superconducting nanowires with Majorana Zero Modes (MZMs) at the wires’ ends. Figure 1: Reading the state of our topological qubit. For nearly a century, these quasiparticles existed only in textbooks.

4 days ago · Microsoft announced a breakthrough new chip, the Majorana 1, which it says will make quantum computing a reality in "years, not decades." The Majorana 1, pronounced "My-orana" and named after ...

4 days ago · Microsoft claims that building its first quantum-computing chip required that it create a new state of matter, which it is referring to as a topological state.

2 days ago · The design of the Majorana 1 processor is supposed to fit up to a million qubits, which may be enough to realize many significant goals of quantum computing—such as cracking cryptographic codes ...

3 days ago · The Majorana was first proposed nearly 90 years ago as a particle that is its own antiparticle, which means two Majoranas will annihilate when they encounter one another. With the right conditions ...

3 days ago · What is a Majorana Zero Mode? To understand Microsoft’s research, it’s essential to grasp the concept of Majorana zero modes, or MZMs. These are special types of quantum states that exist at the ends of certain superconducting wires. Unlike conventional particles, which have distinct matter and antimatter counterparts, Majorana particles ...
