The Majorana 2 quantum processor is built from topological qubits, and its creators claim it can sustain quantum coherence for an average of 20 seconds — orders of magnitude longer than the milliseconds that conventional chips last.

Some will question its credibility – but the alternative future to the one imagined in the Global Justice Report is far more bleak

• ‘An equal and habitable world is possible’: academics set out sweeping vision for planetary survival

In our increasingly dystopian world, who wouldn’t want to at least be open to a utopian antidote? The Global Justice Report, published on Thursday, outlines how to build a prosperous, equitable world within safe planetary boundaries. It’s a push from the modern eco-socialist left in a global battle for ideas that will shape the future.

Based on past social achievements and future energy transformation, it indicates that the overwhelming majority of people on the planet could, by the end of the century, work less and earn more – while keeping temperatures down and avoiding much of the current destruction of nature. It is an ambitious, comprehensive and upbeat plan, and a stronger argument around which to build a political campaign than abstract goals of net zero or decarbonisation.

With dozens of companies, from small startups to tech giants, pursuing quantum computing, there's a steady flow of results as they try to find a path to utility. We typically focus on new technologies and major landmarks, which can obscure the fact that any big success will inevitably have been built on a lot of incremental progress.

The past few weeks have seen two companies release progress reports on how they're trying to get the technologies closer to general use. None of these represents a major breakthrough, but all are absolutely necessary for the technology to advance. The idea here is to convey the hard work required to move us closer to something useful.

Microsoft does material science

Microsoft is one of the few companies working on topological qubits, based on the distinct physics that occurs when particles are confined. Microsoft's system relies on a thin superconducting wire placed on top of a semiconductor. In superconductors, groups of two electrons form Cooper pairs. But if the wire contains an odd number of conducting electrons—meaning there's a single unpaired electron—it will end up delocalized to both ends of the wire. (Because quantum mechanics is weird.)
