Qedma’s Error-Mitigation Software Poised to Accelerate Quantum Advantage Before Fault-Tolerant Hardware Arrives
July 3, 2025
Quantum computers promise breakthroughs in fields like finance, drug discovery, and materials science but remain fragile due to errors—one of the biggest challenges the industry faces. Google recently highlighted the error-correction abilities of its new chip, Willow, while IBM aims to deliver a fault-tolerant quantum computer by 2029. IBM also partners with startups like Qedma, an Israeli company focused on error-mitigation software rather than hardware.
Qedma’s flagship software, QESEM, analyzes noise patterns during quantum computations to suppress errors in real-time and mitigate others afterward. This approach allows quantum circuits up to 1,000 times larger to run accurately on today’s imperfect hardware, bypassing the need to wait for fully fault-tolerant machines.
IBM’s VP of Quantum, Jay Gambetta, stressed the importance of community collaboration, working with both hardware innovators like Pasqal and software-focused firms such as Qedma and Algorithmiq. He believes this teamwork will lead to widely accepted demonstrations of “quantum advantage”—the point where quantum computers outperform classical ones on specific problems. Such breakthroughs are likely to begin with academic challenges before expanding into practical use cases.
Qedma’s CEO Asif Sinay says the startup may soon demonstrate clear quantum advantage. Sinay, a physicist and Talpiot alum, leads a team backed by $26 million from investors including IBM and Glilot Capital. Qedma’s software is available through IBM’s Qiskit platform and has been tested on IonQ’s quantum computer. The startup is also collaborating with Japan’s RIKEN to integrate quantum and supercomputing resources.
With plans to grow its staff from about 40 to 50-60 employees, Qedma aims to sell directly to quantum end users while partnering with hardware manufacturers. This helps domain experts like quants or chemists run noisy quantum circuits with specified accuracy and resource trade-offs, without needing deep quantum expertise.
Qedma’s approach offers a shortcut to quantum advantage by mitigating errors without requiring additional qubits—a key advantage before fully scalable quantum computers arrive. While others like French startup Alice & Bob focus on fault-tolerant architectures using “cat qubits,” Qedma seeks to boost current hardware performance. The ideal balance of qubit quality and quantity depends on the task, but all agree quantum computing’s future depends on tackling these error challenges.
