Quantum computers might soon actually be useful, researchers have said after a new breakthrough. A new study showed that a quantum computer could be used for calculations that are beyond the capabilities of our current best classical – or non-quantum – computers. It means that the technology could soon be useful in practical applications, the researchers suggest. For years, quantum computing experts have been hopeful that the technology could allow for entirely new kinds of calculations, which might be useful across battery research, medicines and more. But the current versions are given to a host of problems, including the fact that they are prone to errors. Quantum computers need to be able to fix those errors more quickly than they accumulate. But even the best quantum computers have struggled to do so, meaning that practical use of the technology has remained beyond our grasp. New research from IBM showed that those errors could be mitigated, however, and a quantum computer could be used in ways that a classical computer could not. As such, the results “herald further opportunities for quantum processors to emulate physical systems that are far beyond the reach of conventional computers”, scientists away from the research say. Unlike many other similar breakthroughs – which focus on the extra speed that a quantum computer can provide – this new research focuses on the scale of the computer. Researchers used more 127 qubits, the equivalent of bits on a classical computer, to do research that classical computers do not have enough memory for. The breakthrough is described in a new paper, ‘Evidence for the use of quantum computing before fault tolerance’, published in Nature today.

A dead “vampire” star is feeding on a nearby companion and expelling cannonballs and its behaviour has left astronomers stunned. The dead star is located around 4,500 light-years away and, until now, has baffled astronomers with its unusual behaviour. It is a rapidly spinning neutron star, otherwise known as a pulsar, that has been given the name PSR J1023+0038, shortened to J1023. It emits radiation from both its poles that occasionally reach Earth and also appears to have two different “settings” of brightness. Initially, the behaviour of J1023 confused experts, but now they believe that the stark difference in brightness levels has to do with the star launching out matter over short spaces of time. Maria Cristina Baglio, leader of the research team and scientist at New York University, Abu Dhabi, said in a statement: “We have witnessed extraordinary cosmic events where enormous amounts of matter, similar to cosmic cannonballs, are launched into space within a very brief time span of tens of seconds from a small, dense celestial object rotating at incredibly high speeds.” In addition to the pulsar emitting matter, over the last 10 years, scientists have witnessed the star pulling material from its companion star. The material it is stealing forms a structure called an accretion disk that forms around the star itself. Since it began feeding, the star has been alternating between between “low” and “high” power modes. During moments of high power, the star shines brightly with a variation of X-rays, ultraviolet and visible light. During low power, it emits radio waves and appears much dimmer. In June 2021, experts witnessed a star shooting out hot, luminous matter that has been compared to a cosmic cannonball as the star continually switched modes. J1023 has fascinated experts, who have been able to explain the way the star behaves by observing it. Despite solving many of its mysteries, the scientists aren’t done with it yet. With the Extremely Large Telescope (ELT) in northern Chile currently under construction, it is hoped that when it is ready, scientists will once more be able to observe the pulsar. Sergio Campana, research co-author and Research Director at the Italian National Institute for Astrophysics Brera Observatory, said: “The ELT will allow us to gain key insights into how the abundance, distribution, dynamics and energetics of the inflowing matter around the pulsar are affected by the mode switching behavior.” Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

The creator of the hugely popular AI bot ChatGPT has launched a controversial project that offers users a free share of cryptocurrency in exchange for their biometric data. Nearly four years after founding Worldcoin, OpenAI boss Sam Altman announced on Monday that the crypto wallet and app is now available in countries where it is not banned for regulatory or legal reasons. More than 1.5 million people signed up to the venture prior to its official launch, each receiving a share of Worldcoin tokens in exchange for scanning their iris using a silver orb developed by the startup. The biometric data was used to verify each individual’s “unique personhood” and ensure that no one signed up more than once. Each person will now be able to use the Worldcoin token, which is currently valued at $2.59 (£2), according to CoinMarketCap, having begun trading on Monday just below $2. Worldcoin (WLD) is similar to other cryptocurrencies like bitcoin, in that it uses blockchain technology to enable digital transactions. According to its website, people can use it for “remittances, [to] tip artists, [and] buy and sell goods and services”. The main differentiator is the way that users sign up, with privacy advocates warning that it could lead to a black market of people’s iris scans. Worldcoin has defended its technology by claiming that its orb is only used to check that a person is unique and has not signed up before. The startup’s website states: “We don’t want to know who you are, just that you are unique”. Worldcoin co-founder Alex Blania wrote in a note published on Monday that he believed Worldcoin “could drastically increase economic opportunity, scale a reliable solution for distinguishing humans from AI online while preserving privacy, enable democratic processes, and eventually show a potential path to AI-funded universal basic income.” He added: “Worldcoin is an attempt at global scale alignment, the journey will be challenging and outcome is uncertain. But finding new ways to broadly share the coming technological prosperity is a critical challenge of our time.” Worldcoin does not list the countries in which it operates – The Independent has reached out for further information – though it is not yet available in Mr Altman’s native US. The startup founder was only able to sign up himself on a trip to Europe earlier this year. “Like any really ambitious project, maybe it works out and maybe it doesn’t, but trying stuff like this is how progress happens,” Mr Altman tweeted following Worldcoin’s launch. “In either case, we especially love our haters, it gives us energy, please keep it coming.” Read More What is superintelligence?
