Quantum Computing Inc. (QCi) unveiled an integrated quantum security platform at ECOC 2026, combining high-dimensional Quantum Key Distribution (QKD) with hardware-based Quantum Identity Authentication (QIA). This platform leverages QCi’s Quantum Zero-Knowledge Proof (QZKP) technology for secure authentication and is compatible with existing telecommunications networks.

SK Telecom and KISTI have developed a digital twin for Quantum Key Distribution (QKD) networks, allowing simulation and verification of network performance before physical deployment. This platform, unveiled at ECOC 2026, uses ETSI standards to connect a Key Management System with a virtual QKD network simulator, enabling cost-effective optimization and multi-vendor interoperability.

IonQ partners with SDT to deploy a Superion 256 quantum system and establish a SiV quantum memory assembly hub in South Korea, expanding their collaboration from software to hardware. This agreement strengthens IonQ's presence in the Asia-Pacific region, supporting biomedical and pharmaceutical research through hybrid quantum infrastructure.

QuEra Computing has opened an office in Maryland's Discovery District, joining the Capital of Quantum initiative. This expansion includes a partnership with UMD's QLab, providing cloud access to QuEra's 256-qubit Aquila neutral-atom quantum computer.

QuEra Computing and HPE are partnering to integrate QuEra's neutral-atom quantum processing units (QPUs) with HPE Cray supercomputers, enabling on-premises, hybrid quantum-classical supercomputing for national laboratories and enterprises. This collaboration aims to develop integrated hardware, co-design algorithms, and establish low-latency software for secure and efficient high-performance computing.

Babcock International Group and Arqit Quantum Inc. successfully demonstrated quantum-safe tactical communications at DVD 2026, using Arqit’s NetworkSecure software to encrypt operational data across various networks. This collaboration showcases a software-defined encryption protocol for securing tactical data against post-quantum threats within existing military communication infrastructure.

Quantum XChange partnered with Carahsoft to distribute its FIPS-validated Phio TX platform to federal agencies, helping them meet post-quantum migration deadlines. The platform provides a crypto-agile management overlay, allowing agencies to hot-swap post-quantum algorithms and protocols without re-architecting applications.

Microsoft Quantum has opened a 15,000-square-foot Quantum Research Center in Maryland, partnering with the University of Maryland and supported by the Capital of Quantum initiative. The facility features a hardware makerspace, classified research zones, and testing infrastructure for quantum system integration and workforce training. Microsoft also unveiled its Quantum Development Kit (QDK) for analytics and published a paper on scalable logical qubits.

Zapata Quantum has launched Quantum Pilot, a cloud-based platform designed to automate quantum application discovery, resource estimation, and software verification. The platform aims to bridge the gap between quantum hardware advancements and the ability of organizations to identify and prioritize high-value enterprise use cases. It achieves this through its Quantum Graph for dynamic knowledge mapping, Quantum Engine for automated algorithm selection and hardware benchmarking, and Quantum Assurance for formal software verification.

Oxford Quantum Circuits (OQC), in collaboration with Citi and the National Quantum Computing Centre (NQCC), completed a study evaluating Quantum-compressed Physics-Informed Neural Networks (QPINNs) for financial derivative pricing. The research demonstrated that QPINNs can significantly reduce model complexity without sacrificing pricing accuracy, offering a promising avenue for more efficient financial modeling. However, the study also identified challenges related to compression efficacy in specific areas and the need for improved classical-quantum integration as quantum hardware develops.
