Microsoft says new quantum chip 1,000 times more reliable than predecessor
Microsoft Claims New Quantum Chip Achieves 1,000-Fold Reliability Boost
Microsoft has announced a significant breakthrough with its latest quantum processor, stating that the new chip is vastly more reliable than its predecessor. This advancement brings the company closer to its goal of deploying a quantum computer capable of solving commercially valuable problems within the next three years.
At the core of quantum computing are qubits, which hold the potential to address complex questions that overwhelm traditional supercomputers. However, these qubits are notoriously fragile and unstable. Microsoft reports that the qubits on its new "Majorana 2" chip survive for an average of 20 seconds, a dramatic increase from the mere milliseconds achieved by the earlier "Majorana 1" model. This enhancement equates to a 1,000-fold improvement in reliability. The tech giant illustrates this leap by comparing it to the difference between a mobile phone requiring daily charging and one that only needs to be charged every few years.
"We will have a quantum machine in 2029 that can solve commercially viable, reasonable problems," said Zulfi Alam, Corporate Vice President of Microsoft Quantum. However, Alam acknowledged that substantial progress remains. While the current chip contains only 12 qubits, a commercially viable device would require millions.
Verifying Microsoft’s assertions is challenging, as the company cites commercial confidentiality and does not publicly disclose all technical details. Nevertheless, the global competition to master this technology is intense, driven by its potential to handle computational tasks that are currently impossible for even the most powerful conventional computers.
Microsoft has dedicated two decades to developing a quantum computing approach known as "topological." This method relies on harnessing the properties of a quasi-particle predicted in the 1930s by Italian physicist Ettore Majorana. To achieve this, Microsoft had to utilize a novel state of matter distinct from the traditional solid, liquid, and gas phases.
Paul Stevenson, a physics professor at the University of Surrey, remarked that the company’s timeline is plausible, provided their research substantiates their claims. "Microsoft appears to have made a leap in their attempt to produce viable topological qubits," Stevenson noted. "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."
The company’s focus on topological qubits has not been without controversy. In 2018, Microsoft was compelled to retract a paper published in the journal Nature after it claimed to have found evidence of the Majorana particle. Despite facing significant skepticism from experts—including physicist Henry Legg of the University of St Andrews, who previously described Microsoft’s quantum research as having "moved firmly away from science and entered the realm of faith"—the company persisted. Its first Majorana chip was eventually released in 2025.
Addressing the past criticism, Jason Zander, Executive Vice President of Microsoft Quantum and Discovery, stated, "We stand behind it 100%." He emphasized the company’s commitment to scientific rigor and open debate, encouraging critics to "read the papers and look what's there" and to consult the experts who have received detailed information from Microsoft.
Microsoft is currently in the final phase of a development program managed by the US Defense Advanced Research Projects Agency (DARPA). The agency’s objective is to "verify and validate the firm's utility-scale quantum computer concept." Microsoft asserts that it has shared all relevant data, including commercially sensitive information, with DARPA for evaluation.
However, a paper released alongside the announcement has not undergone peer review, a process involving assessment by independent experts. Consequently, scientists consulted by the BBC have requested additional information. The second-generation Majorana chip operates on the same principles as the first but achieves greater efficacy partly because researchers substituted aluminum with lead as the superconductor. While the team is leveraging artificial intelligence to accelerate and enhance their efforts, Zander highlighted that human scientists remain the driving force behind the work.
