Key Takeaways
- At Build 2026, Microsoft introduced the Majorana 2 quantum chip with a strategic roadmap for commercially viable quantum computing by 2029
- The latest chip employs lead-based superconductors replacing aluminum, achieving performance enhancements of up to 1,000x in certain benchmarks
- Majorana 2 boasts 12 qubits compared to its predecessor’s 8, extending qubit stability from less than 12 milliseconds to beyond 20 seconds
- Scientific community voices concerns over Microsoft’s limited public disclosure of verification data for its quantum breakthroughs
- Trading at $441.31 with a 4.17% decline, MSFT stock appears approximately 20% undervalued according to GuruFocus metrics
Microsoft has taken a significant stride forward in quantum computing technology. During the June 2 Build 2026 developer conference, the technology giant presented its Majorana 2 chip while establishing a concrete 2029 deadline for delivering a commercially practical quantum computing solution.
Shares of MSFT experienced a 4.17% decrease, settling at $441.31 when the announcement was made.
This latest chip represents the next generation following the initial Majorana chip launched twelve months prior. The upgraded version features 12 qubits versus the previous 8, while achieving a remarkable extension in qubit stability—jumping from under 12 milliseconds to exceeding 20 seconds. This represents substantial progress for a field historically challenged by decoherence issues.
Microsoft’s 2029 timeline aligns with IBM, which recently announced a $10 billion quantum development investment and established a specialized chip division with Trump administration support.
Revolutionary Lead-Based Design
The transition from aluminum to lead superconductors represents the most significant technical innovation. This isn’t merely an incremental adjustment—lead atoms possess greater mass and exhibit distinct behaviors at quantum dimensions. Microsoft credits AI-powered materials science platforms for solving the challenge of utilizing lead, which dissolves in water, while preventing degradation during the fabrication process.
Jason Zander, Microsoft’s executive vice president responsible for quantum initiatives, identified this as the pivotal innovation. The company reports achieving a 1,000-fold performance enhancement across specific metrics. “The reason why people don’t use it to build chips is it requires an incredibly specialized process,” Zander explained. “We figured it out.”
The foundation of Microsoft’s quantum strategy relies on Majorana quasiparticles, whose existence remained unconfirmed until Microsoft’s claimed observation. This assertion continues to generate debate within scientific circles.
Scientific Community Raises Questions
Skepticism persists among researchers. Scientists like Henry Legg from the University of St. Andrews have challenged Microsoft’s claims, contending that insufficient data has been made available for independent scientific validation. The journal Science indicated in 2024 that it was conducting a review of data from a 2020 Microsoft quantum paper. Detractors maintain that comparable transparency concerns exist regarding the most recent research.
Microsoft maintains that proprietary information constraints prevent complete public data disclosure, though relevant findings have been provided under confidentiality to DARPA, which is assessing various quantum computing methodologies.
“We’ve done enough of the physics to really have great data,” Zander stated.
Based on GuruFocus analysis, MSFT holds a GF Score of 97 out of 100, earning maximum 10/10 scores across profitability, growth, and valuation categories. The stock trades at a P/E ratio of 26.27x, representing a discount to its five-year median of 34.15x.
Company insider transactions over the preceding three months reveal zero purchases, with insiders divesting $5.6 million worth of shares.
