Interesting approach alert! QUBO-based SVM tested on QPU (Neutral Atoms). A recent study, "QUBO-based SVM for credit card fraud detection on a real QPU," explores the application of a novel quantum approach to a critical cybersecurity challenge: credit card fraud detection. Here are some of the key findings: * QUBO-based SVM model: The study successfully implemented a Support Vector Machine (SVM) model whose training is reformulated as a Quadratic Unconstrained Binary Optimization (QUBO) problem. This approach could leverage the capabilities of quantum processors. * Performance: The results demonstrate that a version of the QUBO SVM model, particularly when used in a stacked ensemble configuration, achieves high performance with low error rates. The stacked configuration uses the QUBO SVM as a meta-model, trained on the outputs of other models. * Noise robustness: Surprisingly, the study observed that a certain amount of noise can lead to enhanced results. This is a new phenomenon in quantum machine learning, but it has been seen in other contexts. The models were robust to noise both in simulations and on the real QPU. * Scalability: Experiments were extended up to 24 atoms on the real QPU, and the study showed that performance increases as the size of the training set increases. This suggests that even better results are possible with larger QPUs. Practical implications: This research highlights the potential of quantum machine learning for real-world applications, using a hybrid approach where the training is performed on a QPU and the testing on classical hardware. This approach makes the model applicable on current NISQ devices. The model is also advantageous because it uses the QPU only for training, reducing costs and allowing the trained model to be reused. * Ideal for cybersecurity and regulatory issues: The study also observed that the model preserves data privacy because only the atomic coordinates and laser parameters reach the QPU, and the model test is done locally.

🔐 Breaking RSA with ~1M physical qubits? That’s the breakthrough outlined in a recent paper by Craig Gidney at Google: 📄 https://lnkd.in/dQZuNaHt The work proposes optimized circuit constructions and error correction layouts that reduce the qubit requirements for factoring RSA-2048 from ~20 million (2019 estimates) to just 1 million physical qubits—a 20× improvement. This dramatically shifts the horizon for practical quantum attacks on today’s cryptographic standards. ⚠️ If validated, these results substantially accelerate the urgency for quantum readiness—not in theory, but in practice. At BlueQubit, we're focused on developing quantum software solutions that help enterprises and defense organizations prepare for and transition to the post-quantum era. That means tools for identifying cryptographic risk, supporting hybrid classical-quantum architectures, and integrating quantum solutions into existing workflows. 🚀 Algorithmic advances like this reshape timelines, risk models, and strategic priorities. For sectors with long data retention or sensitive infrastructure, now is the time to take quantum threats seriously—and plan accordingly. 🛡️ #QuantumComputing #PostQuantumCryptography #Cybersecurity #QuantumReadiness #BlueQubit #ShorAlgorithm #PQCTools #EnterpriseSecurity #DefenseTech

💡 Wow! This past week marked a major leap forward in rolling out post-quantum cryptography algorithms to protect against “store now, decrypt later” attacks with major updates in OpenSSL 3.5.0 & OpenSSH 10.0 ⬇️ 🔐 What is a “Store Now, Decrypt Later” attack? It’s a forward-looking threat, where adversaries capture encrypted data today and hold onto it, waiting until large-scale quantum computers are powerful enough to break current encryption algorithms (like RSA & ECC) using Shor’s algorithm and decrypt the data. This is particularly dangerous for sensitive long-term information like financial records, important intellectual property and national security data. 🛡️ Why last week’s updates matter: Both OpenSSH and OpenSSL took big steps in implementing post-quantum cryptography (PQC), algorithms designed to remain secure even against quantum computers. 🧩 OpenSSH 10.0 Highlights (https://lnkd.in/gP5q3q7M): • 🚫 Deprecated outdated DSA & classic Diffie-Hellman key exchanges. • 🔐 Default key exchange now uses MLKEM-768, a quantum-safe and NIST-standardized algorithm. • 🔒 Isolated the SSH authentication process into a separate memory space using ssh-auth, mitigating the impact of login-related vulnerabilities like Terrapin or RegreSSHion. 🔐 OpenSSL 3.5.0 Highlights (https://lnkd.in/gmtgVVzv): • ✅ Adds support for three newly standardized PQC algorithms: ML-KEM (Key Encapsulation), ML-DSA (Digital Signatures) & SLH-DSA (Hash-Based Signatures). • 🔄 Sets AES-256-CBC as the new symmetric default over older, weaker ciphers. • 📅 This is a Long-Term Support (LTS) release, supported through 2030. Kudos to the maintainers and contributors pushing these critical projects forward. The future of secure communication just got a lot more resilient. 😁 #CyberSecurity #PostQuantumCryptography #OpenSSL #OpenSSH #QuantumResistant #StoreNowDecryptLater #Encryption #Infosec #TechLeadership #PQC #NIST

⛳️ Merging Quantum with Zero Knowledge: Privacy & Security centric How to Revolutionizing Digital Security? 🔒💻 🚀 The future of digital security is here, and quantum computing is leading the charge! In my recent study on Quantum Security of Zero-Knowledge Protocols at Universitat Politècnica de Catalunya, I explored how quantum zero-knowledge protocols (QZKPs) are transforming privacy and authentication in the quantum era. 🔐 Why does this matter? Resistance to quantum attacks: Quantum algorithms like Shor's threaten traditional cryptographic systems. QZKPs, built on quantum-resistant problems like lattices, ensure protection against these threats. Absolute privacy: Thanks to quantum properties like entanglement and the no-cloning theorem, QZKPs guarantee that no sensitive information is revealed during authentication. Robust authentication: Experiments show QZKPs can authenticate identities over 60 km with quantum bit error rates (QBER) below 11%, instantly detecting malicious attempts. 🌟 From blockchain to electronic voting, QZKPs are opening new frontiers for digital security. Yet, the challenge remains to bridge the gap between quantum theory and practical applications. 💡 What do you think about the impact of quantum computing on cybersecurity?

Quantum Computers Capable of Breaking Cryptography in 10 years? The Federal Office for Information Security (BSI) in Germany has released an updated study on the development of quantum computing technologies and their impact on cybersecurity. 💡 Key takeaways: 🔑 A cryptographically relevant quantum computer could become a reality within 16 years - 4 years earlier than previously estimated. Advanced developments in error correction and hardware even suggest this timeline might shrink to as little as 10 years, though further verification is needed. Quantum computers hold immense potential as a key technology of the future. However, they also pose a significant threat to cybersecurity. Here's why: Our current digital infrastructure relies heavily on public-key cryptography, which, for now, is secure with classical hardware. But once universal quantum computers with sufficient capabilities emerge, this security paradigm shifts. Data encrypted today but not "quantum-safe" can be intercepted now and decrypted later when such quantum systems are available - what we call "store now, decrypt later." This not only compromises confidentiality but also endangers other critical objectives like authenticity. 🔒 The BSI urges organizations to start transitioning to quantum-safe cryptography now to mitigate these risks and safeguard our future digital infrastructure.
