Computing faster with quasi-particles

Majorana particles are very peculiar members of the family of elementary particles. First predicted in 1937 by the Italian physicist Ettore Majorana, these particles belong to the group of so-called fermions, a group that ...

In a new quantum simulator, light behaves like a magnet

Physicists at EPFL propose a new "quantum simulator": a laser-based device that can be used to study a wide range of quantum systems. Studying it, the researchers have found that photons can behave like magnetic dipoles at ...

Spacetime—a creation of well-known actors?

Most physicists believe that the structure of spacetime is formed in an unknown way at the Planck scale, i.e., at a scale close to one trillionth of a trillionth of a metre. However, careful considerations undermine this ...

Disrupting crystalline order to restore superfluidity

What if you could disrupt the crystalline order of quantum matter so that a superfluid could flow freely even at temperatures and pressures where it usually does not? This idea has been demonstrated by a team of scientists ...

Just seven photons can act like billions

A system made of just a handful of particles acts just like larger systems, allowing scientists to study quantum behaviour more easily.
