Qedma Raises $26M to Solve Quantum Computing Errors
Quantum computing promises to revolutionize industries like finance, medicine, and materials science—but not without solving one critical challenge: quantum error correction. Israeli quantum startup Qedma has just raised $26 million to take on this obstacle, with IBM joining the round as both investor and collaborator.This article breaks down how Qedma’s software is pushing the quantum industry forward, why IBM and other tech giants are investing in error mitigation, and what this means for the future of computing.

How Qedma’s Software Targets Quantum Computing Errors
While many companies developing quantum technology are obsessed with hardware, Qedma is taking a different route. Rather than building quantum machines, the Israeli startup is focused on reducing quantum computing errors through a sophisticated software solution called QESEM—Quantum Error Suppression and Error Mitigation. This tool actively manages and suppresses certain error types during algorithm execution, and mitigates others in post-processing. By doing this, QESEM dramatically boosts the accuracy and reliability of quantum circuits—enabling operations that are up to 1,000 times more complex than previously possible.
What sets QESEM apart is its ability to work with today’s noisy quantum hardware. Instead of waiting for fault-tolerant quantum computers to become widely available, Qedma helps users tap into current systems more efficiently. This is a powerful value proposition, especially for researchers and developers eager to begin real-world experimentation.
Why IBM Invested in Error Mitigation Software
IBM is deeply invested in the quantum ecosystem. Its own roadmap includes building a fault-tolerant quantum computer by 2029, and it’s well aware that achieving true quantum advantage requires more than just powerful chips. That’s where Qedma comes in. According to IBM’s VP of Quantum, Jay Gambetta, the company sees software-based error correction as a vital piece of the puzzle.
By partnering with Qedma, IBM is effectively hedging its bets—combining its hardware expertise with software specialists to accelerate industry progress. Other IBM partners, such as Pasqal and Algorithmiq, are similarly working to enhance different layers of the quantum stack. These collaborations highlight a key industry trend: the road to quantum advantage is a community effort. No single company will own the full stack.
Gambetta believes it will take time to reach consensus on what constitutes real-world quantum advantage. However, companies like Qedma are helping shift that timeline closer by addressing the most immediate technical barriers—namely, quantum computing errors that limit the scalability of current systems.
What Qedma’s Breakthrough Means for the Quantum Industry
With its latest funding round, Qedma is now positioned to scale its software and support a broader range of quantum applications. This could include use cases in drug discovery, complex simulations, and advanced financial modeling—areas that demand large-scale quantum circuits and minimal error tolerance.
Professor Dorit Aharonov, Qedma’s co-founder and a renowned name in quantum computing, believes their technology will bridge the gap between current noisy machines and the robust quantum platforms of the future. By enabling significantly larger and more accurate quantum circuits, Qedma makes quantum experimentation more practical and appealing for institutions and enterprises alike.
Startups like Qedma are playing a pivotal role in shaping the next phase of the quantum race. Their focus on reducing quantum computing errors is not just a technical niche—it’s a foundational requirement for the industry to move from lab experiments to commercial-scale impact. With support from global leaders like IBM, Qedma is poised to become a key player in quantum's coming-of-age story.
