The Majorana 1 chip is powered by a novel Topological Core, which Microsoft claims will enable the development of quantum computers “capable of solving meaningful, industrial-scale problems in years, not decades.”
It said this breakthrough is thanks to the world's first topoconductor, short for topological superconductor, which is a "special category of material" that can create "an entirely new state of matter."
This cutting-edge material can “observe and control Majorana particles to produce more reliable and scalable qubits,” which is short for "quantum bit" and is described as the basic building blocks of quantum computers.
"We took a step back and said 'OK, let's invent the transistor for the quantum age. What properties does it need to have?'" said Chetan Nayak, Microsoft technical fellow. "And that's really how we got here – it's the particular combination, the quality and the important details in our new materials stack that have enabled a new kind of qubit and ultimately our entire architecture."
The announcement likened the revolutionary breakthrough to the invention of semiconductors, which made today’s smartphones and computers possible.
Microsoft said the invention now enables a “clear path” to fitting a million qubits onto a single palm-sized chip, which they say is necessary for quantum computers to reach their fullest potential and deliver real-world solutions. Such could include breaking down microplastics into harmless byproducts or inventing self-healing materials, the company said.
"Whatever you're doing in the quantum space needs to have a path to a million qubits. If it doesn't, you're going to hit a wall before you get to the scale at which you can solve the really important problems that motivate us. We have actually worked out a path to a million,” Nayak said.
At the center of this innovation is the topoconductor, which Microsoft said can create a state of matter that is neither solid, liquid, or gas, but instead a topological state. They said such a material can then be harnessed and used to produce a stable qubit that can be digitally controlled and is small and fast.
Microsoft's quantum computing breakthrough has caught the eye of DARPA—the Department of Defense agency that develops new military technologies—leading to the company's inclusion in the final stage of the US2QC program, alongside one other firm.
Microsoft has successfully integrated eight topological qubits onto a chip designed for million-qubit scalability.
Krysta Svore, a Microsoft technical fellow, described the intricate process: "We are literally spraying atom by atom. Those materials have to line up perfectly. If there are too many defects in the material stack, it just kills your qubit."
This advancement in topological qubit technology could revolutionize various industries, with Microsoft predicting that million-qubit machines may tackle complex problems in fields like chemistry and materials science that currently elude classical computers.
The invention of quantum computers can potentially create self-repairing materials for infrastructure and consumer goods, development of catalysts to decompose microplastics, or boost enzyme efficiency for medical and agricultural purposes.
"From the start we wanted to make a quantum computer for commercial impact, not just thought leadership," said Matthias Troyer, Microsoft technical fellow.
Microsoft envisions a future where quantum computers, paired with AI tools, could transform design and problem-solving across industries.
Troyer explained, "Any company that makes anything could just design it perfectly the first time out. It would just give you the answer. The quantum computer teaches the AI the language of nature so the AI can just tell you the recipe for what you want to make."
