Microsoft says new quantum chip 1,000 times more reliable than predecessor">

['Microsoft has announced a significant breakthrough in its pursuit of quantum computing, revealing a new chip that is 1,000 times more reliable than its previous version. The tech giant claims that the qubits on its new Majorana 2 chip survive for an average of 20 seconds, a substantial improvement over the milliseconds of its predecessor, Majorana 1. This leap in performance is comparable to the difference between a phone that needs charging every day and one that needs charging every few years.', 'The improved reliability of the Majorana 2 chip brings Microsoft closer to its goal of developing a quantum computer that can solve commercially useful problems.

According to Zulfi Alam, corporate vice president of Microsoft Quantum, the company will have a quantum machine in 2029 that can tackle viable, reasonable problems. However, this will require significant further advances, as a practical device would need millions of qubits - the current chip has just 12.', "Assessing Microsoft's claims is challenging due to the company's reluctance to release full details of its research publicly, citing commercial confidentiality. Nevertheless, the firm's approach to topological quantum computing has been a focus of its research for 20 years.

The technology is based on exploiting the properties of a quasi-particle, which had existed only in theory since it was first predicted in the 1930s by Italian physicist Ettore Majorana. While some experts have expressed skepticism about Microsoft's claims, others believe that the company's progress is promising.", "Paul Stevenson, a physics professor at the University of Surrey, said that Microsoft's timeline sounded plausible if its research lives up to its claims. 'Microsoft appears to have made a leap in their attempt to produce viable topological qubits,' he said.

'If they succeed, they will leap from being a player with no production quantum computer, to being a serious player in the race to make the next generation of fault-tolerant machines.' Microsoft's focus on topological qubits has been a long-term bet, and while it faced setbacks, including a retracted paper in 2018, the company remains committed to its approach.", "The potential applications of Microsoft's quantum computer are vast, ranging from solving complex problems like removing microplastics and developing more efficient fertilizers. Jason Zander, executive vice president of Microsoft Quantum and Discovery, emphasized that the company sees a role for humans, AI, and quantum computers working together to accelerate the process of solving these challenges. While the timeline is ambitious, Microsoft's progress has sparked renewed interest in the possibility of quantum computing becoming a reality in the near future.", "Despite the excitement, significant challenges remain.
