Unisys has launched its first Post-Quantum Cryptography (PQC) capability, a cryptographic posture assessment service aimed at helping organizations prepare for emerging quantum threats. The service offers a full inventory and analysis of an organization’s cryptographic assets, identifies vulnerabilities, and provides actionable mitigation strategies. As part of a broader PQC rollout, this launch reflects Unisys’s proactive approach to quantum-era security, addressing the need to safeguard sensitive data against future decryption by quantum computers. While quantum computing is still several years from widespread deployment, current encrypted data may already be vulnerable to “store now, decrypt later” attacks by malicious actors anticipating future quantum [...]

As organizations look to upgrade their IT infrastructure to make their communications quantum safe, one of the approaches is to implement a hybrid classical/quantum approach. This combines together both classical algorithms with quantum algorithms to provide added protection against attacks against both the classical and quantum public key encryption. This significantly increases the difficulty for an attacker because they would need to break both the algorithms before they could get access to the encryption key. To this end, the European Telecommunications Standards Institute (ETSI) has launched a new post-quantum security standard, Efficient Quantum-Safe Hybrid Key Exchanges with Hidden Access Policies (ETSI TS 104 015), to [...]

Quantum algorithms company Phasecraft has developed a new simulation technique called THRIFT (Trotter Heuristic Resource Improved Formulas for Time-dynamics), enabling quantum simulations to run 10 times larger and for 10 times longer while significantly reducing circuit complexity and computational cost. Published in Nature Communications, the THRIFT algorithm addresses a longstanding challenge in quantum simulation: how to efficiently simulate dynamic quantum systems without overwhelming quantum hardware resources. Quantum simulations play a critical role in modeling materials and molecules for clean energy, advanced drug design, and other fields. Current methods rely on Trotter decomposition to approximate time evolution by splitting a quantum system [...]

Quantum computing architecture startup Iceberg Quantum has raised $2 million AUD ($1.26M USD) in pre-seed funding led by Blackbird Ventures and UK-based LocalGlobe. The announcement coincides with a new strategic collaboration with PsiQuantum to develop fault-tolerant architectures for PsiQuantum’s silicon photonic quantum computing platform, currently under development in Brisbane. Iceberg Quantum is addressing the challenge of quantum error correction overhead, a major bottleneck to scalable quantum computing. By applying low-density parity-check (LDPC) codes—pioneered in part by co-founders Felix Thomsen, Larry Cohen and Sam Smith during their PhD work at the University of Sydney —the company aims to reduce the qubit overhead [...]

Xanadu and Corning Incorporated have announced a strategic collaboration to co-develop customized low-loss optical fibre and fibre-array solutions for networking photonic quantum computing chips. The joint effort will leverage Xanadu’s expertise in ultra-low-loss photonic chip components and Corning’s advanced innovations in optical fibre to enable fault-tolerant, utility-scale photonic quantum computing. The goal is to address critical interconnect challenges for scaling architectures like Xanadu’s recently demonstrated Aurora quantum system. The effort builds on Xanadu’s recent demonstration of Aurora, a 35-chip fibre-networked photonic quantum system using 13 kilometers of optical fibre, as reported in Nature. While Aurora establishes the architectural foundation for scaling [...]

Classiq Technologies has announced a major milestone in financial quantum computing, achieving up to 95% quantum circuit compression in Monte Carlo simulation algorithms for credit portfolio risk management. The project was conducted in partnership with Sumitomo Corporation and Mizuho–DL Financial Technology, aiming to assess the feasibility of quantum algorithms in real-world financial applications, particularly in simulating large-scale probabilistic models used for Value at Risk (VaR) calculations. Monte Carlo methods are widely used in finance for tasks such as derivative pricing and asset risk assessment but are computationally intensive due to the large number of random scenarios required. Mizuho–DL FT introduced a [...]

Qunova Computing has introduced its HI-VQE Chemistry function to IBM’s Qiskit Functions Catalog, offering researchers a new tool for solving electronic structure problems in quantum chemistry. The Handover Iterative Variational Quantum Eigensolver (HI-VQE) algorithm, which underpins the function, combines quantum and classical computing resources to efficiently estimate the ground state of molecular systems. This hybrid quantum-classical approach focuses on a subset of the most relevant electron configurations, significantly reducing computational complexity while maintaining high accuracy. By leveraging quantum hardware to explore candidate configurations and classical computing to calculate resulting wave functions, the algorithm enables researchers to study larger molecular systems and construct precise potential energy surfaces. These [...]
