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 /, [1] Italian: [ˈɛttore majoˈraːna]; born 5 August 1906 and disappeared 1938) was an Italian theoretical physicist who worked on neutrino masses. Majorana was a supporter of Italian Fascism and a member of the National Fascist Party, a fact documented by historians such as Joseph Francese [2] and ...

5 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.

5 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 ...

5 days ago · Microsoft today introduced Majorana 1, the world’s first quantum chip powered by a new Topological Core architecture that it expects will realize quantum computers capable of solving meaningful, industrial-scale problems in years, not decades.. It leverages the world’s first topoconductor, a breakthrough type of material which can observe and control Majorana particles to produce more ...

5 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 ...

5 days ago · Microsoft's Majorana 1 chip includes eight topological quantum bits. Microsoft claims that building its first quantum-computing chip required that it create a new state of matter, which it is...

5 days ago · Majorana 1 is a step toward the future of quantum computing, promising to tackle problems that are currently too complex for today’s classical computers. This chip, built on topological qubits, is a fresh approach, different from what competitors like Google and IBM are doing with superconducting or trapped-ion qubits.

Apr 10, 2020 · MIT researchers have observed mysterious Majorana fermions in islands of gold. The discovery could lead to new family of robust qubits for quantum computing.
