Microsoft launched what it calls as world’s first Quantum Processing Unit (QPU) powered by a topological core that will scale quantum computing to a million qubits on a single chip.
A study published in Nature describes Microsoft’s new hardware-protected topological qubit, which uses a novel material called a topoconductor. This material enables topological superconductivity, a previously theoretical state of matter.
Microsoft developed a method to control quantum information using Majorana Zero Modes (MZMs), particles that store quantum data in a way that minimizes errors.
Building the world’s first fault-tolerant prototype (FTP) based on topological qubits: Microsoft is on track to build an FTP of a scalable quantum computer — in years, not decades — as part of the final phase of the Defense Advanced Research Projects Agency (DARPA) Underexplored Systems for Utility-Scale Quantum Computing (US2QC) program.
Quantum error correction
The company has also introduced a new approach to quantum error correction. Unlike traditional methods that rely on precise analog signals, Microsoft’s system uses digital pulses to manage qubits. This simplifies control and makes it easier to scale quantum computing for real-world applications.
As part of the Defense Advanced Research Projects Agency’s (DARPA) Underexplored Systems for Utility-Scale Quantum Computing (US2QC) program, Microsoft has advanced to the final phase of a competition to develop a fault-tolerant quantum prototype.
Microsoft’s roadmap includes moving from single-qubit devices to scalable arrays, supporting reliable quantum computing. The company has already placed eight topological qubits on a chip designed to house one million. A quantum computer at this scale could help solve complex problems in materials science, chemistry, and sustainability.
Microsoft sees its partnership with DARPA as a step toward achieving practical quantum computing, which could drive scientific advancements in multiple fields.
