Majorana-highway on a chip(Nanowerk News) The first experimental evidence of a Majorana fermion in Delft 2012 led to a wave of scientific enthusiasm: control such particles are a holy grail in quantum science and technology.
|Quantum chips based on Majorana fermions promise error-protected quantum computations. However, the fabrication of Majorana-devices is an extremely challenging task.|

|A collaboration of researchers has now combined novel nanowires with a high-quality interface to other required materials on a chip (Nature, "Ballistic superconductivity in semiconductor nanowires").|
|This allows for bullet-like collisionless quantum transport of charges through the nanowires: a requirement for larger-scale Majorana-based experiment.|
|The novel methods open doors towards quantum computations based on Majorana fermions, allow for the exploration of new quantum effects in such materials ánd can have future applications in energy-efficient electronics.|
