Novel gate may enhance power of Majorana-based quantum computers

Quantum computers hold great potential, but they remain hard to build because their basic components—individual quantum systems like atoms, electrons or photons—are fragile. A relentless and noisy background constantly bombards the computer’s data.

Shaking Bosons into Fermions

Particles can be classified as bosons or fermions. A defining characteristic of a boson is its ability to pile into a single quantum state with other bosons. Fermions are not allowed to do this. One broad impact of fermionic anti-social behavior is that it allows for carbon-based life forms, like us, to exist. If the universe were solely made from bosons, life would certainly not look like it does. Recently, JQI theorists* have proposed an elegant method for achieving transmutation--that is, making bosons act like fermions.

Finding Majorana - Update

A group at Delft University in the Netherlands led by L.P. Kouwenhoven has published experimental signatures of Majorana particles. The experiment precisely follows the theoretical proposals made in 2010 by Sankar Das Sarma and his collaborators at JQI.
