Microsoft has made a significant breakthrough in quantum computing by unveiling its new quantum architecture, Majorana 1, which is designed to scale up to one million topological qubits on a single chip. The company’s engineers used a novel approach called Majorana quasiparticles to create a stable and controllable qubit.
Unlike traditional qubits, which are prone to decoherence and noise, Majorana 1 uses a special pattern known as a zero mode state that is inherently stable and small. This architecture, dubbed the Topological Core powered by “topoconductors,” can coax the existence of Majorana quasiparticles using nanowires, superconductors, and advanced physics.
The company’s technical fellow, Krysta Svore, explained that a topological qubit is reliable, small, and controllable, solving the noise problem that creates errors in traditional qubits. Currently, Majorana 1 holds eight of these qubits, but Microsoft aims to scale up to one million qubits.
However, some scientists remain skeptical about Microsoft’s claims due to concerns over the accuracy of their research methodology and the existence of similar phenomena that can mimic Majorana quasiparticles without the underlying topological nature. The scientific community is watching closely as Microsoft continues to refine its architecture and demonstrate its capabilities in computing calculations.
