Arabic version: مايكروسوفت تكشف عن شريحة مايورانا 2 مع موثوقية كوانتية محسّنة

Microsoft has announced its new Majorana 2 quantum chip, claiming it is 1,000 times more reliable than its predecessor. This advancement is expected to bring quantum computing closer to solving commercially viable problems within the next three years. The Majorana 2 chip boasts qubits that can survive for an average of 20 seconds, a significant improvement over the milliseconds provided by the earlier model.

According to BBC News, Zulfi Alam, corporate vice president of Microsoft Quantum, stated that a functional quantum machine could be developed by 2029, although achieving this will require further advancements as the current chip contains only 12 qubits.

Microsoft has dedicated 20 years to developing a topological approach to quantum computing, which utilizes a theoretical quasi-particle first predicted in the 1930s by physicist Ettore Majorana. The new chip’s design incorporates lead as a superconductor, replacing aluminum from the first generation, enhancing its effectiveness.

The tech giant’s claims have drawn skepticism over the years, particularly following a retraction of a 2018 paper that initially reported evidence for the Majorana. Despite the doubts, Microsoft remains committed to its research. Jason Zander, executive vice president of Microsoft Quantum and Discovery, emphasized the importance of scientific rigor and public debate in the field.

While the Majorana 2 chip shows promise, challenges remain in the broader quantum computing landscape, particularly regarding qubit stability. As companies race to create scalable quantum computers, Microsoft’s advancements could position it as a significant player in the future of quantum technology.
