HardwarePhysicist Challenges Microsoft's Quantum Chip Breakthrough Claims
A study published in Nature has cast doubt on Microsoft's claims about its Majorana quantum chips, the foundation of its topological qubit technology. The company unveiled its first chip in February 2025, touting it as a breakthrough for quantum computing. However, physicist Henry Legg of the University of St Andrews re-examined Microsoft's data and concluded that the evidence for Majorana particles in the device is unconvincing. Without these particles, he argues, building a functional qubit for quantum computing is impossible.
