Korea Telecom (KT), a major telecommunications provider, has initiated a collaboration with HEQA Security, a company specializing in quantum-safe encryption. This strategic partnership aims to accelerate the deployment of next-generation secure communication technologies and strengthen telecom infrastructure against emerging threats from quantum computing by integrating Quantum Key Distribution (QKD) technologies. HEQA Security will contribute its advanced QKD systems, Sceptre Link and Sceptre Duo, which are designed for carrier-grade environments. These systems utilize quantum random number generation and secure key management protocols to protect core telecom operations, supporting flexible network configurations for integration into KT's infrastructure. The capabilities of these quantum-safe systems [...]

Diagrams Showing Two Different Approaches for Generating High-Fidelity Logical Non-Clifford Gates(Controlled Hadamard on Left, T-Gate using Code Switching on Right) We have reported in the QCR recently on several research projects to create quantum error correction codes (see here, here, here, and here), but one of the most significant challenges for implementing a full fault tolerant quantum computer is being able to robustly support a complete, universal gate set that could conceivably implement any quantum algorithm. It is one thing to create logical qubits using a specific error correction code, but it is another thing to be able to perform gate [...]

Xanadu has opened a $10 million advanced photonic packaging facility in Toronto, Ontario, aiming to enhance Canada's quantum supply chain resilience and technical capacity. This facility is characterized as the sole end-to-end, ultra-low loss photonic packaging facility of its kind in the country, enabling domestic production of high-performance quantum components essential for building fault-tolerant quantum computers. The Honourable Evan Solomon, Minister of Artificial Intelligence and Digital Innovation and Minister responsible for the Federal Economic Development Agency for Southern Ontario, officially opened the new facility. Xanadu's advanced packaging line integrates custom tooling and proprietary processes developed in-house. Its capabilities encompass ultra-low loss [...]

The EuroHPC Joint Undertaking (EuroHPC JU) has inaugurated PIAST-Q in Poznań, Poland, marking the first operational deployment of a EuroHPC quantum computer and the first EuroHPC infrastructure located in Poland. PIAST-Q is a laser-based trapped-ion quantum computer, supplied by AQT | Alpine Quantum Technologies GmbH (AQT) of Innsbruck, Austria, and hosted and operated by the Poznańskie Centrum Superkomputerowo-Sieciowe (PCSS) in Poland. The system offers a performance of 20 physical qubits and was notably delivered and deployed several months ahead of its contractual timeline. PIAST-Q is designed with features including high fidelity universal quantum gates for minimizing computational errors, long coherence times [...]

F5 (NASDAQ: FFIV) has unveiled new comprehensive Post-Quantum Cryptography (PQC) readiness solutions seamlessly integrated into its Application Delivery and Security Platform. These solutions are designed to equip organizations with the necessary tools to secure applications and APIs against emerging quantum computing threats while maintaining high performance and scalability. This initiative addresses the fundamental shift in cybersecurity posed by the quantum era, where traditional asymmetric cryptography is projected to become vulnerable, leading to "harvest now, decrypt later" attack strategies. The F5 platform simplifies the transition to quantum-safe protections by providing a fully integrated and scalable approach for both application delivery and security. [...]

IonQ (NYSE: IONQ) and researchers from the University of Washington's InQubator for Quantum Simulation (IQuS) have performed the first known simulation of a process called "neutrinoless double-beta decay" using a quantum computer. This simulation, conducted on IonQ's Forte Enterprise quantum system, observed a "lepton-number violation"—a phenomenon never directly simulated before on a quantum computer—which has implications for understanding the universe's imbalance between matter and antimatter. The simulation technique employed by the team allows for the modeling of nuclear dynamics on yocto-second (10⁻²⁴ seconds) timescales. The approach was co-designed and customized for IonQ's trapped-ion quantum hardware, leveraging its all-to-all connectivity and native [...]

Researchers from The University of Tokyo and IBM have demonstrated Krylov Quantum Diagonalization (KQD) on an IBM Heron quantum processor, successfully simulating the Heisenberg model on a 2D heavy-hex lattice of up to 56 sites. This experiment represents the simulation of one of the largest many-body systems achieved on a quantum processor to date. The findings of this research have been published in Nature Communications. KQD is an algorithm designed for high-precision energy estimation from dynamic behavior, operating without requiring variational optimization. The method constructs subspaces of the many-body Hilbert space using Trotterized unitary evolutions executed on the quantum processor, with [...]

Quantum Dice, a University of Oxford spin-out specializing in quantum random number generator (QRNG) technology, and Astute Group, a global electronics distributor and supply chain partner, have announced a strategic global distribution partnership. As part of this agreement, Astute Group has joined Quantum Dice’s authorized partner program to accelerate access to its DISC™-protected QRNG chip products. The collaboration will focus on sectors with high security requirements, including aerospace, defense-grade systems, government, and critical infrastructure, aligning with the recently published UK Strategic Defence Review. At the core of Quantum Dice’s QRNG products is its patented source-device independent self-certification (DISC™) protocol. This protocol [...]

Qunnect, a company deploying quantum entanglement-based protocols over commercial fiber, has closed an oversubscribed Series A extended financing round, securing $10 million. The round was led by Airbus Ventures, with additional participation from Cisco Investments and Quantonation. This new funding is designated to fuel the development of turn-key variants of Qunnect's Carina product suite, enabling demonstrations for new use cases with strategic industry partners. Qunnect has already deployed two metropolitan quantum networks in major cities (New York City and Berlin). Qunnect's products, including its Carina product suite, support the real-world deployment of scalable data networks based on quantum physics. These commercially [...]

Global Data Quantum, a Spanish company, has added its Quantum Portfolio Optimizer software to IBM's Qiskit Functions Catalog. This new application function was introduced at the IBM Quantum Partner Forum 2025 in London, enabling finance professionals to leverage quantum computing resources for investment strategy backtesting and dynamic portfolio optimization. This addition expands the catalog's offerings, providing a dedicated tool for financial use cases at the 100+ qubit scale. The Quantum Portfolio Optimizer is designed to abstract the complexities of quantum development, requiring only domain-specific inputs such as historical or expected asset prices. It translates this financial information into a problem formulated [...]
