Microsoft projects commercial quantum computers will operate in data centers by 2029, capable of calculations classical machines cannot perform. Zulfi Alam, Microsoft’s corporate vice president of Quantum, announced this timeline, citing increased confidence in the technology’s commercial readiness. The company aims to deliver machines with commercial value through calculations unachievable by current systems.
Zulfi Alam stated that the clarity of the 2029 timeline has improved compared to previous years. “I would not be able to say this with this much clarity last year, but this year, I can state to claim that by 2029 you will have machines that will have commercial value, meaning that they will be doing calculations that classical machines cannot do,” Alam said. This projection follows Microsoft’s introduction of the Majorana 1 chip in February 2025.
Microsoft’s Majorana 1 chip utilizes a topological qubit architecture based on a novel material called a topoconductor. This technology aims to produce qubits that are more reliable and scalable than previous iterations. The company claims this approach could enable quantum computers to solve industrial-scale problems in years rather than decades. Microsoft was selected to advance to the final phase of DARPA’s Underexplored Systems for Utility-Scale Quantum Computing program, which targets the creation of the industry’s first utility-scale fault-tolerant quantum computer.
Competition among major technology firms is intensifying as they race to achieve practical quantum computing. IBM announced at its 2025 Quantum Developer Conference that it expects verified quantum advantage by the end of 2026 and fault-tolerant quantum computing by 2029. Amazon introduced its Ocelot chip in February 2025, employing a cat qubit architecture. Amazon states this design could reduce the resources required for quantum error correction by up to 90%.
Google demonstrated its Willow chip in December 2024, achieving below-threshold error rates while scaling qubit counts. This achievement is considered a milestone the field had pursued for nearly 30 years. Analysts expect quantum systems to function as hybrid accelerators alongside classical computing resources like CPUs and GPUs, rather than replacing them entirely. Alam emphasized that “the future lies in hybrid systems, where CPUs, GPUs, and QPUs work together,” requiring robust error correction and specialized quantum operating systems.
The potential for quantum computing to reduce energy consumption in data centers is a significant point of interest for industry operators. UBS analysts noted that quantum computers could solve specific problems in 200 seconds, a task that would take conventional supercomputers 10,000 years. This efficiency could lead to lower energy usage in data centers. Research conducted at Cornell indicates that quantum-based optimization frameworks could reduce energy consumption in AI data centers by up to 12.5%.
Industry roadmaps converge on a window between 2028 and 2032 for the deployment of operational quantum systems. Experts forecast that systems will feature tens of thousands of physical qubits per rack between 2029 and 2031, with customers accessing tens to hundreds of logical qubits. The quantum computing market is projected to grow from approximately $2.5 billion in 2025 to over $16 billion by 2035.
