Krol The scientists have demonstrated how to structure light such that its polarization behaves like a collective of spins in a ferromagnet forming half-skyrmion (also known as merons). To achieve this the light was trapped in a thin liquid crystal layer between two nearly perfect mirrors. Skyrmions in general are found, e.g., as elementary excitations of magnetization in a two-dimensional ferromagnet but...

 E-Mail IMAGE: Quantum particles lined up in a lattice form the basis for an error-tolerant quantum processor. view more  Credit: Uni Innsbruck/Harald Ritsch Even computers can miscalculate. Already small disturbances change stored information and corrupt results. That is why computers use methods to continuously correct such errors. In quantum computers, the vulnerability to errors can be reduced by storing quantum information in more than a single quantum particle. These logical quantum bits are less sensitive to errors. In recent years, theorists have developed many different err...
