Discovery agentic AI, and that platform is arguably the more consequential part of this announcement.

To put that in plain terms: most quantum chips today can hold their fragile computational state for a fraction of a second before losing it. Majorana 2 holds it for up to a minute.

Discovery agentic AI actually did here

The common read on this story is that AI designed the chip. The reality is more specific, and arguably more interesting. The decision to switch the superconducting material from aluminium to lead, which

says is the single change most responsible for the reliability improvement, came out of years of conventional materials research, not an AI recommendation.

Discovery’s agents did was everything around that: managing fabrication workflows, automating measurements that previously took weeks each, breaking down nearly two decades of siloed research data, and surfacing correlations that no single researcher could hold in their head across that volume and variety of information.

“As you run AI agents on this data, they’re able to essentially resynthesize and make correlations that we as humans cannot see because no single individual has that much vision across that much data,” said Zulfi Alam, corporate vice president for quantum at

.

That framing matters because it shifts the story from “AI built the chip” to something more accurate: agentic AI compressed the experimental cycle. What would have required extensive trial-and-error to find the right atomic-level recipe for the chip’s crystalline structure could, through AI-driven simulation, be narrowed to a single targeted experiment. 

“In the new world order, through simulations, you can see where the highly probable target is. And then with that knowledge, you ideally only have to experiment once,” Alam said.

The measurement problem, solved

One of the more concrete wins the team describes involves qubit measurement; the process of detecting quantum states by determining whether there’s an even or odd number of billions of electrons on a semiconductor wire. When done manually, this takes weeks.

tried to automate it a few years ago using earlier machine learning and couldn’t. 

With agentic AI built on

Discovery, they created a specialised agent that now runs the process automatically and continuously, building three-dimensional maps of qubit conditions at a pace no individual researcher could replicate.

“Using agentic AI to automate the measurements was a game changer,” Alam said. The agent handles parallel voltage adjustments across hundreds of parameters simultaneously, something human researchers, thinking linearly and structurally, cannot do.

The commercial pitch is clear: the same capability stack that the quantum team used to compress its development timeline is now available to any organisation running intensive R&D.

The 2029 claim, in context

’s revised quantum timeline deserves a note of editorial distance. The company has moved its target from 2033 to 2029 based on Majorana 2’s progress, which is a significant acceleration, but quantum roadmaps have a history of optimistic compression. The 1,000x reliability figure refers specifically to improvements over Majorana 1’s qubits, not a direct benchmark against competing approaches from IBM or

, which use fundamentally different architectures. 

Nayak’s own framing is honest about the incremental nature of this: “Where are we relative to last year? We’re 1,000 times better.” That’s a meaningful year-on-year milestone. Whether it holds at the pace required to reach utility-scale quantum computing by 2029 is the question no one, including
