Quantum computing is entering a decisive phase as one startup abandons the interim step most competitors still chase. QuEra Computing, a leader in neutral-atom quantum architectures, recently detailed a plan to skip the noisy intermediate-scale quantum (NISQ) era entirely, aiming instead for a fully error-corrected system with over 10,000 physical qubits by 2029. This announcement follows Amazon’s earlier pledge to host a QuEra system with similar specs by 2028, underscoring the rapid acceleration in quantum hardware development.
QuEra skips the NISQ detour
Traditionally, quantum computing has relied on NISQ devices—systems with hundreds of qubits plagued by high error rates—to test algorithms and explore near-term applications. QuEra’s current hardware, such as its 260-qubit system, operates within this paradigm, offering researchers a platform for early experiments. However, Yuval Borger, QuEra’s Chief Technology Officer, emphasized that the company has made a strategic pivot away from selling these error-prone systems. Instead, QuEra is focusing solely on building machines capable of sustaining logical qubits, which require error correction to function reliably in real-world applications.
The decision reflects a growing consensus that NISQ devices, while valuable for proof-of-concept work, are not scalable enough to deliver the fault tolerance needed for commercial quantum computing. By bypassing this phase, QuEra is betting on a faster path to practical quantum advantage—a state where quantum computers outperform classical systems in specific tasks.
A two-step leap to 2029
QuEra’s roadmap outlines a two-stage journey to its 2029 target. The first step is the 2028 deployment of a system with thousands of physical qubits and low error rates, paving the way for hundreds of logical qubits. This aligns with Amazon’s announcement to host a QuEra machine under its cloud quantum computing service. The second step, slated for 2029, involves scaling the system to over 10,000 qubits while maintaining error correction across multiple logical qubits.
This aggressive timeline contrasts sharply with broader industry trends. Most quantum computing firms, including IBM and Google, are still refining error correction techniques for systems with far fewer qubits. For example, IBM’s 1,000+ qubit systems, while impressive, still face significant challenges in reducing error rates to practical levels. QuEra’s approach leverages its neutral-atom technology, which uses laser-trapped atoms to represent qubits—a method that offers long coherence times and scalable architectures.
Industry implications and skepticism
QuEra’s announcement has sparked both optimism and scrutiny within the quantum computing community. Proponents argue that skipping the NISQ era could accelerate the arrival of fault-tolerant quantum computers, which are essential for solving problems like drug discovery, materials science, and optimization. Critics, however, question whether such a rapid transition is feasible, given the technical hurdles in error correction and qubit scalability.
Industry analysts note that QuEra’s roadmap hinges on several critical milestones, including advances in error mitigation, qubit connectivity, and control systems. The company’s reliance on neutral-atom technology also introduces unique challenges, such as maintaining qubit stability over extended periods and scaling up atom arrays without introducing errors. Yet, if successful, QuEra’s strategy could redefine the quantum computing landscape, forcing competitors to reassess their own timelines.
What’s next for quantum computing?
The coming years will be pivotal for quantum computing as companies like QuEra, IBM, and Google race to achieve fault tolerance. While QuEra’s 2029 target is ambitious, it underscores a broader shift toward prioritizing error correction and scalability over incremental improvements. For researchers and businesses alike, the message is clear: the quantum era is not just on the horizon—it’s being built now, one logical qubit at a time.
