Summary

  • Microsoft is aiming to produce a topological quantum computer using Majorana quasiparticles, which are not real particles and emerge as special patterns of behaviour.
  • While the company’s pursuit has faced setbacks, including a high-profile research paper retraction by associated researchers in 2018, Microsoft now claims it is on track to build a working computer within a few years, with a blueprint for building out chips that each contain a million qubits.
  • This week, the company announced that it has tested a topological qubit and wired up a chip that contains eight, with a target of producing a few thousand qubits within the next few years, which is when these computers are expected to really show their potential.
  • While others are more sceptical and call for further testing, outside researchers are cautiously optimistic about these results.
