Above: nodeQ’s offerings enable infrastructure intelligence for the quantum internet and distributed quantum systems.
nodeQ is a UK-based quantum technology startup founded in 2020–2021 which develops software infrastructure for quantum and hybrid classical–quantum networks, with a focus on security, resilience, and transition planning. The company’s tools are designed to help organizations assess existing network architectures and prepare for a cost-efficient transition to quantum-safe communications as quantum computing capabilities advance.
nodeQ’s flagship offerings include telaQ™ a digital-twin platform for modeling and planning quantum and quantum-safe networks, and PQtunnel™, a deployable solution for establishing post-quantum secure communications. Together, these platforms are touted to support risk analysis, architectural trade-off evaluation, and phased migration strategies aligned with regulatory and security requirements.
nodeQ was founded by Stefano Pirandola, a leading researcher in quantum information science whose work has shaped modern understanding of quantum communications and networking. His academic background spans physics and computer science, including postdoctoral research at MIT and a professorship at the University of York (UK), where his research bridges theoretical limits and system-level design.
The PLOB bound defines the fundamental rate-loss limits of quantum communication, providing a realism check on what scalable quantum networks can achieve in practice.
Pirandola is best known as a co-author of the PLOB bound, introduced in a seminal 2017 Nature Communications paper that defines the fundamental repeaterless rate-loss tradeoff for quantum and private communication. Often compared to Shannon capacity in classical information theory, the PLOB bound provides a constraint-based foundation for evaluating feasibility, cost, and architecture choices—an approach directly informing nodeQ’s emphasis on evidence-based network modeling, cost-aware planning, and security-driven design decisions.
nodeQ provides software tools that enable governments, critical-infrastructure operators, and enterprises to analyze, simulate, and plan quantum-safe network transitions. Its platforms support scenario testing across hybrid environments which combine classical networking, post-quantum cryptography, and emerging quantum communication elements, allowing stakeholders to evaluate security posture, performance constraints, and investment timing before deployment.
Rather than assuming immediate adoption of quantum hardware, nodeQ focuses on incremental, policy-aligned migration strategies that reduce risk, support compliance, and preserve operational continuity as quantum technologies mature.
