Neue Phase der Materie: 2D-Bose-Glas könnte Quantenspeicherung voranbringen

> Physicists at the Cavendish Laboratory in Cambridge have successfully produced the first two-dimensional Bose glass, an unusual phase of matter that defies conventional ideas in statistical mechanics.

> To achieve this, the researchers used overlapping laser beams to generate a quasiperiodic pattern. When they introduced ultracold atoms—cooled to near absolute zero, at nanokelvin temperatures—into this structure, the atoms arranged themselves into a Bose glass. “Localisation is not only one of the toughest nuts to crack in statistical mechanics, it can also help to advance quantum computing”

> As its name implies, the Bose glass exhibits certain glass-like properties, with all particles in the system becoming localized. This means that each particle remains confined to its position, without interacting or blending with its neighbors.

> If coffee behaved in this way, for example, stirring milk into it would result in a permanent pattern of black and white stripes that never mix into a uniform color.

> In a localized system like the Bose glass, particles don’t mix with their environment, which suggests that quantum information stored within such a system could be retained for much longer periods. This property has significant implications for quantum computing and information storage.
