Scientists Just Found A Use For The Hashtag In Quantum Computing

Twitter's hashtag just turned 10, and wouldn't you know it, scientists just worked out a far better use for it - at the nanoscale.

See, it turns out that a criss-cross pattern of semiconducting nanowires is the perfect structure to help manipulate a particular type of quasiparticle into quantum bits.

This nano-hashtag structure at scales of a billionth of a metre should help the quasiparticles, known as Majorana fermions, be more easily formed into a qubit: the building blocks for quantum computers.

Majorana fermions are shown to be far more robust than existing qubit technology, and scientists developing this technology reckon it will lead to a new generation of quantum architecture that will end with a scalable, fault-tolerant universal quantum computer.

This kind of architecture is what Microsoft's Station Q is looking for, and recently announced a multi-year partnership at the University of Sydney. One of the researchers involved with this new research is Dr Maja Cassidy, a senior researcher at Station Q Sydney, which is based at the University of Sydney Nanoscience Hub.

"Networks of nanowires are crucial to demonstrate how Majorana fermions interact through braiding," said Dr Cassidy. "These will be a fundamental building block for topological quantum computation."

Dr Cassidy worked on the research team while she was at TU Delft in the Netherlands.

    So...I am assuming the whole process is cooled to around 1 kelvin if they are using Aluminium as a superconductor? Or does the "spraying" they do actually align the Aluminium atoms in a cooper paring configuration? In which case the whole process still needs to be cooled to around 100 kelvin.

    That being said, could they scale up the hash tag formation so that they could get more Majorana using circle packing?
