QuEra Computing says useful quantum computers arrive in two years

QuEra Computing asserts that useful quantum computers will arrive within two years, a claim that challenges the longstanding view of the technology as a distant prospect.

Chief Commercial Officer Yuval Boger publicly stated this timeline, predicting a shift from “toys” to tools capable of tackling complex problems. This assertion sparked debate among quantum professionals, particularly regarding the difficult task of “scaling” systems to the necessary qubit counts. QuEra distinguishes its prediction by framing scaling as a series of testable steps, supported by eight peer-reviewed papers and a commitment to deliver its Libra fault-tolerant system on Amazon Braket in 2028.

Neutral Atom Architecture Enables All-to-All Qubit Connectivity Neutral atom architectures circumvent a significant bottleneck in quantum processing by enabling all-to-all qubit connectivity, a feature QuEra Computing uses in its roadmap toward scalable, fault-tolerant systems. Unlike architectures reliant on fixed chip layouts or signal routing, QuEra’s platform physically moves neutral atoms to establish interactions, eliminating the need for SWAP gates and the associated latency when manipulating distant qubits. This physical agility is rooted in the inherent uniformity of neutral atoms, a benefit stemming from the absence of manufacturing variability present in fabricated superconducting circuits. The ability to bring any qubit into contact with any other is not merely an architectural detail; it directly impacts the quantum error correction tax, a critical factor in achieving practical quantum computation. High-rate error-correcting codes are progressively reducing the ratio of physical to logical qubits required for fault tolerance, and QuEra’s Libra system, slated for delivery on Amazon Braket in 2028, is designed for 256 error-corrected logical qubits from just over 10,000 physical qubits, targeting a logical error rate of 10⁻⁶. This design reflects a shift in the field, moving away from assumptions of needing a thousand physical qubits to protect a single logical qubit. QuEra’s roadmap extends to a Gigaquop-class system, aiming for over 1,000 logical qubits from roughly 20,000 physical qubits with a 10⁻⁹ error rate, building on techniques already validated in peer-reviewed publications. Continuous operation of large qubit arrays also addresses a historical challenge. QuEra and collaborators at Harvard and MIT have demonstrated continuous operation of a 3,000-qubit neutral-atom array for over two hours through mid-computation atom replenishment, as published in Nature. This advancement mitigates concerns about atom loss from the trapping mechanism, a previously significant obstacle to long-duration quantum computations. The platform operates at room temperature, bypassing the complexities and costs associated with dilution refrigeration required by cryogenic platforms, simplifying deployment and reducing operational overhead. Beyond hardware improvements, QuEra emphasizes co-design partnerships to establish concrete use cases for its technology. This approach, formalized through the FTQC Founder’s Circle, focuses on identifying quantum-relevant problems, building classical benchmarks, and utilizing emulation before accessing limited hardware resources. The company’s strategy focuses on building a quantum ecosystem prepared to utilize them effectively when Libra arrives, asserting that the most crucial time to begin building quantum capability was yesterday, and the next best time is now.

Libra System Roadmap: Validating Fault Tolerance Through Peer Review QuEra Computing is anchoring its claim of near-term quantum utility to a publicly available roadmap, comprised of eight peer-reviewed papers detailing the foundational elements of its Libra fault-tolerant system. This approach directly addresses skepticism surrounding ambitious timelines in quantum computing, a field historically marked by unmet predictions and unresolved scaling challenges. The subsequent Gigaquop-class system, planned for 2028 and 2029, aims to scale to 1,000 or more logical qubits from approximately 20,000 physical qubits, with an even lower error rate of 10⁻⁹. While these figures are roadmap targets, the underlying techniques, including below-threshold error correction demonstrated across up to 96 logical qubits and transversal logical operations, have already been validated in peer-reviewed publications. QuEra’s recent demonstration of practical fault-tolerant magic state generation on its Gemini system further supports this trajectory, QuEra Computing says. The company, founded in 2018 with roots in Harvard and MIT research led by Mikhail Lukin, Markus Greiner, and Vladan Vuletic, has secured funding through a $47M round in October 2024, a $17M Series A, and a $230M Series B (expanded from an initial amount), totaling near $280M. A partnership with Hewlett Packard Enterprise (HPE) resulted in an agreement on September 22, 2026, to integrate QuEra’s fault-tolerant systems with the HPE Cray supercomputing platform, providing on-premise access to quantum resources. This integration, alongside the opening of a new office in Maryland’s Discovery District, underscores the company’s commitment to building a complete quantum ecosystem. The company’s focus on applications in chemistry and materials science, where quantum mechanics governs the underlying behavior, is intended to accelerate the path to demonstrable value.

Shrinking Quantum Error Correction Tax Drives Logical Qubit Scale QuEra Computing projects a functional quantum computer within two years, a timeline anchored to a diminishing “quantum error correction tax” that reduces the number of physical qubits needed to create stable logical qubits.

Chief Commercial Officer Yuval Boger concedes current systems are “toys,” lacking the capability to outperform classical computers for practical tasks, but anticipates a rapid shift as error mitigation improves. This specificity, however, has drawn scrutiny from those questioning the feasibility of scaling quantum systems given the unresolved challenges in maintaining qubit coherence and controlling errors. The company frames its prediction not as a single leap, but as a series of testable steps validated by ongoing research, according to QuEra Computing. QuEra distinguishes itself by focusing on incremental improvements in three key areas: qubit quality, algorithmic efficiency, and the reduction of overhead associated with error correction. Neutral atom qubits, inherently identical due to their natural properties, offer an advantage over manufactured superconducting circuits prone to variability. For years, the prevailing assumption held that protecting a single logical qubit required approximately one thousand physical qubits, a ratio hindering large-scale fault tolerance. “Some commenters welcomed the specificity,” Boger noted, acknowledging the need for concrete milestones in a field often characterized by ambitious but unfulfilled promises. Co-Design Partnerships Establish Near-Term Quantum Usefulness Co-design partnerships are proving central to establishing a pathway toward near-term quantum usefulness, with QuEra Computing actively collaborating with clients to define success criteria before undertaking computational work. Usefulness, the company asserts, isn’t an inherent property of a quantum machine but rather a validation established problem by problem, benchmarked against classical solutions. This approach shifts the focus from abstract capability to concrete application, addressing concerns that fault tolerance alone doesn’t guarantee practical value. Chemistry and materials science currently lead potential application areas, as these fields’ inherent quantum mechanical behavior aligns naturally with quantum hardware modeling. The company’s strategy extends beyond hardware development to encompass a proactive approach to customer engagement, recognizing that organizations in sectors like finance, pharmaceuticals, and manufacturing shouldn’t delay building quantum capability. Waiting until 2028 to begin preparation, according to QuEra, isn’t a neutral position but a decision to forfeit the readiness window currently being utilized by competitors. This emphasis on proactive preparation is underscored by recent demonstrations, which suggest the critical question is no longer if fault-tolerant quantum computing will arrive, but who will be prepared to utilize it upon its arrival, the company says. Every algorithmic improvement further reduces the burden on hardware requirements, contributing to the plausibility of a two-year horizon. Yuval Boger, Chief Commercial Officer at QuEra Computing, explained this convergence in a recent LinkedIn post, sparking debate among quantum professionals and prompting a detailed examination of the necessary conditions for achieving this goal. This iterative approach allows for continuous validation of progress and addresses skepticism stemming from the field’s history of missed timelines. Recent collaborations, including work with Zapata Quantum to develop applications for future systems and a $4 million quantum testbed with Roadrunner Studios, further solidify this commitment to practical implementation and co-design.
