Mitsubishi Electric and OptQC are expanding their strategic partnership through investments and R&D collaborations. OptQC secured JPY 7 billion in Series A2 funding, bringing its total funding to over JPY 20 billion, which will support the development of a 10,000-qubit optical processor and a new Tokyo R&D facility. Mitsubishi Electric, through its ME Innovation Fund, participated in OptQC's funding round and is also leading two national quantum hardware control projects.

Mitsubishi Electric has been selected by NEDO to lead two R&D projects focused on scaling quantum hardware control systems. The first project, "Research and Development of Multi-Qubit-Control Laser Systems," aims to develop low-latency, multi-channel optical systems for neutral-atom and trapped-ion quantum processing units. The second project, "Development of Ultra-Compact, Multi-Channel, Low-Noise Amplifier Modules for Large-Scale Superconducting Quantum Computers," will engineer cryogenic low-noise amplifier modules for superconducting quantum computers. These projects aim to achieve commercial deployment of million-qubit-scale systems by the 2030s, collaborating with AIST and academic institutions.

EPB has launched the IonQ Forte Enterprise quantum computer at its Chattanooga Quantum Center, making it the first commercial U.S. hub to integrate trapped-ion quantum processing units and photonics-based quantum networking. Initial access is for the EPB Quantum Computing Fellows, with commercial service opening in October 2026. This launch is supported by workforce and academic initiatives and positions Chattanooga as a leader in quantum technology.

EigenQ and Silicon Valley Acquisition Corp. have secured $45 million in convertible note financing, providing $22.5 million upfront and the remainder upon closing their $3 billion SPAC merger. This funding will accelerate EigenQ's quantum-safe security commercialization, expand delivery, and support R&D, with the company expected to list on Nasdaq as EIGQ in Q4 2026. EigenQ plans to focus on government, defense, and critical infrastructure sectors, leveraging partnerships with companies like TD SYNNEX, AMD, WNC Corporation, HPE, and Intel.

ICTK and Jiran Security have partnered to launch Q-BRIDGE, an initiative offering end-to-end Post-Quantum Cryptography (PQC) migration for enterprises, governments, and financial sectors. Jiran Security will handle diagnostic auditing, risk assessment, and migration planning, while ICTK will provide hardware-rooted PQC security architecture using its VIA PUF™ (Physically Unclonable Function) Hardware Root of Trust (HRoT) chips. This collaboration aims to streamline PQC transitions by integrating cryptographic inventory discovery with physical PUF-PQC hardware deployment.

Q-SAFE Solutions GmbH has launched a carrier-grade quantum-safe network platform in the EU-27, integrating Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC) with centralized hybrid key management. This system operates over existing fiber-optic infrastructure, eliminating the need for dedicated dark fiber, and is designed for telecommunications providers, critical infrastructure, and government agencies. It aligns with EU technological sovereignty mandates and will be showcased at the European Commission’s QCI Days 2026.

USC and Quantum Elements successfully demonstrated subthreshold surface code scaling on IBM Heavy-Hex processors, overcoming connectivity challenges with a "fold-unfold" SWAP embedding and robust dynamical decoupling. This work, published in Nature Communications, validates that physical quantum processors can achieve distance-scaling error suppression on non-native geometries and introduces a SPAM-aware Entanglement Fidelity metric for accurate logical error rate assessment. The research utilized 156-qubit IBM Heron processors and builds upon their previous collaborative work in classical digital-twin simulation.

Riverlane has established its U.S. headquarters in Maryland's Discovery District to expand its quantum error correction (QEC) technology in North America, fostering collaborations with academic and government partners. This new facility, located near the University of Maryland, will house executive offices and laboratory space. The expansion is part of Riverlane's strategy to advance real-time QEC deployments and workforce development in the quantum technology sector.

Oxford Quantum Circuits (OQC) has launched Erado, an open-source Qiskit simulator for erasure noise and post-selection, integrated into their QCaaS SDK. This tool allows researchers to simulate erasure-aware noise models and evaluate quantum error mitigation techniques, with accompanying research showing postselection can fully mitigate erasure noise below 3.0% error rates, outperforming single-rail architectures. Erado offers flexible simulation modes and precise parameter controls for analyzing the trade-offs of post-selection.

By Sinan Utku Example 1: Implementing a Pauli Z Gate Quantum computing inventions come in a variety of forms. They include hardware and hardware-related inventions that are directed to components of a quantum computer or processes carried out by the hardware to carry out quantum computing processing.  They also include software-related inventions that, e.g., implement a new quantum computing algorithm for achieving a useful end.  Quantum computing inventions are often useful, contain a technological advance and in many cases include specific hardware components.  However, as illustrated by the American Axle and Symantec cases, none of these properties are sufficient to confer [...]
