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.

The era of quantum computing is closer than we think, and it’s going to change the foundations of digital security. NIST’s recent draft publication, NIST IR 8547 (link in 1st comment), outlines critical steps organizations must take to transition to post-quantum cryptography (PQC). Why This Matters Now ⏩ Quantum computers will eventually break traditional encryption algorithms like RSA and ECC. While secure today, these systems won’t be once quantum systems mature. NIST’s Post-Quantum Standards ⏩ NIST has selected algorithms like CRYSTALS-Kyber (for key establishment) and CRYSTALS-Dilithium (for digital signatures) to lead the transition. What Organizations Should Do ⏩ Inventory Cryptography: Assess where and how cryptographic algorithms are used. ⏩ Test PQC Algorithms: Experiment with hybrid solutions combining classical and quantum-safe algorithms. ⏩ Engage with Vendors: Ensure tech partners are preparing for PQC compatibility. Challenges Ahead ⏩ Performance trade-offs: Some PQC algorithms require more computational resources. ⏩ Interoperability: Integrating new cryptographic methods into legacy systems isn’t trivial. ⏩ Timeline pressure: The longer you delay, the harder it will be to catch up. The message is clear: preparation can’t wait. The organizations that start now will be in a much better position when the quantum era fully arrives.

The CXO’s guide to Quantum Security Customers often tell me that the migration to post-quantum cryptography (PQC) will take them years, and some assets won’t ever be upgraded. While quantum’s long-term threat is clear, security leaders are grappling with the practical, multiyear journey of upgrading potentially thousands of devices, applications and data stores to be quantum-resistant. The “harvest now, decrypt later” threat raises the stakes. Nation-state actors are siphoning and stockpiling encrypted data today, waiting for the arrival of quantum computers to retroactively break it. The implication? Sensitive data may already be in the wrong hands and it’s only a matter of time before it can be put to use. What CXOs need is a clear path forward: Discover - Complete a comprehensive crypto inventory across your environment. You cannot protect what you cannot see. Protect - Achieve post-quantum decryption at scale with NGFW that have crypto-agility built right in, enabling your security as standards evolve.   Accelerate - Leverage segmentation along with emerging new capabilities, like cipher translation, to instantly upgrade legacy devices and applications to secure your data now while your organization upgrades devices and applications.  Read more https://bit.ly/4nVkurw

Quantum-ready blockchain strengthens digital trust by protecting data, smart contracts, and decentralized operations from quantum threats. We must see this evolution as essential for the future of digital ecosystems. Quantum computing is progressing faster than many expected, and traditional encryption could soon be insufficient. Preparing our infrastructures today means protecting the integrity of tomorrow’s data flows. A quantum-safe blockchain applies advanced cryptography designed to resist future decryption algorithms. It enables organizations to automate processes securely, manage collaboration without central authorities, and maintain transparency across complex networks. These qualities will be critical for global businesses that depend on reliability, privacy, and interoperability. The transition toward quantum security is not only a technical necessity but also a cultural shift toward long-term digital resilience. It challenges us to think beyond current risks and to build trust into every layer of our digital interactions. #QuantumComputing #Blockchain #CyberResilience

What Google’s latest quantum experiment means for digital security right now Google’s new Quantum Echoes experiment confirms progress in verifying quantum behaviour using the 65-qubit Willow processor. This development has sparked many discussions about whether Q-day is now closer. Q-day refers to the moment when a quantum computer can break widely used encryption standards like RSA-2048 and ECC. The foundation for this concern comes from Shor’s algorithm, which shows that a sufficiently capable quantum system could factor large numbers faster than classical methods, undermining the mathematics behind public key encryption. Today’s quantum devices operate with only 100s of noisy qubits, far below the millions of logical qubits needed to threaten encryption. The concept of “harvest now, decrypt later” is central to security planning. This means that encrypted data gathered today could be decrypted once quantum capability reaches the threshold. Organisations must move toward quantum safe cryptography such as CRYSTALS-Kyber for encryption and Dilithium for digital signatures. These algorithms are now standardised and recommended. For banks, cloud services, government agencies, and critical infrastructure providers, this clarity is an urgent reminder to review security roadmaps. Taking early steps in post-quantum readiness will strengthen long-term data protection and maintain trust in digital systems. If your security strategy does not yet include post-quantum planning, now is the time to start defining that roadmap.

A recent comprehensive study, issued by Federal Office for Information Security (BSI) on the Status of #Quantum #Computer #Development provides a sober, evidence-based assessment of progress, risks, and timelines, particularly relevant for #cryptography, #cybersecurity, and strategic planning, with a focus on applications in #cryptanalysis. Key takeaways: • Quantum advantage is real, but still narrow Quantum computers have demonstrated advantage only on highly specialized benchmark problems. Broad, application-relevant superiority remains out of reach. • Cryptography is the primary strategic risk driver Shor’s algorithm continues to pose a credible long-term threat to RSA and elliptic-curve cryptography, while symmetric cryptography (e.g. AES) remains comparatively resilient with appropriate key lengths. • Fault tolerance is the true bottleneck Error rates not qubit counts are the dominant constraint. Scalable, fault-tolerant quantum computing requires massive overheads in error correction and infrastructure. • Leading hardware platforms are converging Superconducting qubits, trapped ions, and neutral atoms (Rydberg) currently lead the field, with rapid progress but no clear single winner. • #NISQ systems are not a near-term cryptographic threat Noisy Intermediate-Scale Quantum (NISQ) devices lack the depth and reliability needed for meaningful cryptanalysis, despite frequent hype. • A realistic timeline is emerging Based on verified advances in error correction, a cryptographically relevant quantum computer may be achievable in ~10–15 years—not decades, but not imminent either. • “Harvest now, decrypt later” remains a credible risk Sensitive data encrypted today may be vulnerable in the future, reinforcing the urgency of post-quantum cryptography migration. • Security preparedness must start now Transition planning, crypto-agility, standards development, and quantum-readiness assessments are no longer optional for governments and critical sectors. 👉 Bottom line: quantum computing is progressing steadily, not explosively, but its long-term implications for cybersecurity and digital trust demand early, structured, and risk-based action today. https://lnkd.in/eMui-D_W

Post-Quantum Cryptography (PQC): Why We Must Prepare Before Quantum Computers Arrive What exactly is PQC? Is it a tool? An attack? A new policy? Let’s make it clear. PQC (Post-Quantum Cryptography) is not a product or software you install. It’s a new generation of cryptographic algorithms designed to protect our data from the power of future quantum computers. Every secure connection we make today from online banking to VPNs relies on mathematical problems like RSA or Elliptic Curve Cryptography (ECC). These are strong today because even the world’s fastest supercomputer would take years to break a 2048-bit RSA key. But a quantum computer doesn’t work like a traditional one. It doesn’t calculate with just 1s and 0s. Instead, it uses qubits capable of existing in multiple states at once. This means quantum computers can process massive parallel calculations that our current machines can’t. That’s where the concern begins. Algorithms like RSA and ECC can be broken in hours or days using quantum algorithms such as Shor’s algorithm. I give you example, imagine your bank’s SSL certificate that secures online transactions today. It uses RSA-2048. If a threat actor records that encrypted traffic today and in a few years gets access to a quantum computer they could decrypt that communication easily. This is called “Harvest Now, Decrypt Later”. It means attackers can steal your encrypted data now, store it and decrypt it in the future once they have quantum power. For organisations like banks, government agencies or healthcare providers this is a huge risk. Sensitive data must remain confidential for decades. So what is PQC really? PQC is the next wave of encryption standards that are resistant to quantum attacks. Instead of relying on problems like factorisation, PQC algorithms use lattice-based, code-based or hash-based methods that even a quantum computer can’t easily solve. In fact, NIST has already announced its first three official PQC standards this year a sign that the transition is already happening globally. Quantum computing will change everything. It’s not about fear it’s about readiness. PQC is our way of ensuring that even when quantum arrives, our communications, banking, healthcare and national data remain protected. The future of cybersecurity will not just be about detecting attacks, but about securing cryptography before it becomes breakable.

Quantum Computing in Banking -> Encryption Risk or Security Revolution? Quantum computing is no longer theoretical. Banks and financial institutions are already preparing for a world where today’s encryption standards won’t be enough. In this visual breakdown, I walk through: → Why current encryption was built for classical computers → How quantum machines can break RSA, SSL, and blockchain keys in minutes → The real impact on data theft, identity loss, and systemic financial risk → Quantum-safe cryptography and QKD as the next layer of defense → How leaders like JPMorgan, IBM, and BIS are already testing quantum-resistant systems → Why quantum is not just a threat but a major opportunity for fraud detection, risk modeling, and portfolio optimization Quantum computing will reshape the financial ecosystem. The question isn’t if it’s how quickly institutions can evolve their security, payments, and infrastructure models to stay resilient.
