Caltech and Oratomic researchers suggest 10,000 qubits could crack encryption schemes

Quantum Computing Threats to Encryption Schemes

Researchers at Caltech and Oratomic have posited that quantum computers with 10,000 qubits could potentially undermine widely used encryption protocols, including elliptic curve cryptography (ECC) and RSA-2048. These findings, detailed in preprint submissions to arXiv.org, indicate a notable decrease in the qubit count required for cryptographic attacks compared to prior estimates. However, no verified encryption breaches have been reported in 2026, and the results are based on theoretical models rather than confirmed capabilities. The Perplexity response highlights that practical error correction for large-scale cryptanalysis remains unattained, emphasizing that these represent potential future risks rather than immediate threats.

Advancements in Quantum Error Correction

The breakthrough relies on advancements in quantum error correction (QEC), which facilitates the creation of reliable logical qubits from error-prone physical qubits. Conventional QEC methods required millions of physical qubits to produce a single logical qubit, but the new schemes developed by Caltech and Oratomic achieve a significantly higher yield. For example, the Oratomic team’s work suggests RSA-2048 encryption could be compromised with 100,000 physical qubits and 10 days of computation, while ECC could be broken with 26,000 qubits in a single day. These figures represent a substantial reduction from earlier projections of 2,000,000 qubits, underscoring rapid progress in QEC technology. Experts caution that while these developments are significant, they do not yet translate to fully functional quantum computers capable of executing complex cryptographic attacks.

Technical Milestones in Quantum Error Correction

Quantum error correction is central to this breakthrough. By transforming faulty qubits into reliable ones, QEC enables quantum computers to operate with greater stability and efficiency. The new methods, such as quantum low-density parity check (LDPC) codes, allow researchers to generate more logical qubits per physical qubit than traditional approaches. For instance, the study by Caltech and Oratomic indicates their QEC scheme produces significantly more logical qubits compared to conventional methods, which is critical for achieving the computational power needed to crack encryption. The reduction in required qubits signifies a fundamental shift in quantum computer design and operation. The Iceberg Quantum paper from February 2026, which estimated RSA encryption could be defeated in a week with 100,000 qubits, further supports this trend. Additionally, Pinnacle’s February 2026 architecture claims to reduce the physical qubits needed for breaking RSA-2048 by 10 times, backed by $6 million in funding. These advancements in QEC are making quantum computers more feasible by reducing hardware complexity and resource demands. However, experts note that these developments do not yet equate to fully functional quantum computers capable of executing complex cryptographic attacks.

Timeline for Quantum Threats

The timeline for when quantum computers will pose a real threat to internet security remains debated. According to Google’s blog post, the company is setting a 2029 timeline for migrating to post-quantum cryptography (PQC) to mitigate risks. This timeline reflects recognition of progress in quantum computing hardware and QEC, which are making the development of cryptographically relevant quantum computers (CRQCs) more imminent. Google’s efforts include integrating PQC into Android 17 and Chrome, as well as offering PQC solutions in its Cloud platform. Industry leaders like Scott Aaronson, a computer scientist at the University of Texas at Austin, have termed these studies “quantum computing bombshells”, highlighting the urgency of transitioning to PQC. The National Institute of Standards and Technology (NIST) is also actively working on standardizing PQC algorithms, designed to resist quantum attacks. Despite these efforts, transitioning to PQC presents challenges. Organizations must update cryptographic systems, often requiring significant financial and technical resources, particularly for legacy systems that are difficult to modernize.

Quantum-Safe Encryption Developments

Researchers are developing quantum-safe encryption methods to counter potential quantum attacks. A study by Florida International University (FIU) describes a new encryption system combining quantum encryption with secure internet transmission. This method, which shows a 10–15% improvement over existing techniques, scrambles data using cryptographic keys accessible only to authorized users. The FIU team, funded by the U.S. Army Research Office, tested their approach and found it significantly reduces exploitable data patterns, making encrypted videos substantially harder to crack. The collaboration between FIU and QNU Labs, a cybersecurity company specializing in quantum technologies, is advancing the platform toward commercial application. The team is also scaling the technology to encrypt full-length video files and real-time streams, including video conferencing and surveillance systems. While quantum-based attacks remain rare, cybersecurity agencies worldwide are urging organizations to transition to PQC. The UK’s National Cyber Security Centre, for example, advised large institutions to modernize cryptographic systems by 2035 in 2025, underscoring the urgency of preparing for quantum-enabled threats.

Convergence of Quantum Computing and Cybersecurity

The convergence of quantum computing and cryptography presents both challenges and opportunities. While the potential for quantum computers to break current encryption schemes is a significant concern, it also drives innovation in cybersecurity. The development of PQC and quantum-safe encryption methods reflects the resilience of the cybersecurity community. However, transitioning to these new standards requires coordinated efforts across industries, governments, and academia. As research continues, the focus remains on refining QEC techniques and improving quantum computer efficiency. The urgency to secure digital infrastructure against future threats underscores the importance of proactive measures. By investing in PQC and fostering collaboration between researchers and industry leaders, the cybersecurity landscape can adapt to the evolving technological landscape. The coming years will be critical in determining how effectively the global community can mitigate the risks posed by quantum computing while harnessing its potential for positive advancements.
