Fortaegis Technologies secured $50 million in Series A funding to advance its hardware‑rooted, quantum‑safe secure compute architecture. The company’s leadership features Ilyas Khan, founder of Quantinuum, as chairman, and founder‑CEO Boudewijn Wijnands, with Chris Miller on the U.S. board. Fortaegis’s silicon platform generates dynamic, quantum‑resistant encryption keys from microscopic manufacturing variations, avoiding permanent key storage and eliminating theft vectors. The firm reports 17 patents, 14 pending, and machine‑to‑machine speeds over 200 times faster than software cryptography. Funds will scale [...]

University of Pennsylvania researchers created a four‑qubit Greenberger–Horne–Zeilinger state on a room‑temperature diamond quantum register, entangling the central electron spin of a nitrogen‑vacancy center with three nearby 13C nuclear spins in 14.8 µs. The team used a single XY8 dynamical‑decoupling sequence, turning crosstalk into parallel conditional gates and achieving a ten‑fold speedup over traditional sequential two‑qubit protocols. Gate fidelities reached 0.92 for the four‑qubit state, surpassing prior room‑temperature demonstrations. The method is scalable to other solid‑state platforms and [...]

IBM Research unveiled Spacetime Probabilistic Error Cancellation (Spacetime PEC), a hybrid framework that combines Probabilistic Error Cancellation with post‑selected Quantum Error Detection. The method reduces sampling overhead by exploiting circuit syndrome data to eliminate single‑location errors, achieving up to a 63‑fold decrease in overhead compared to standard PEC. In experiments on a 27‑qubit heavy‑hex processor, Spacetime PEC restored ideal magnetization in Trotterized Ising dynamics while cutting total sampling effort dramatically. The approach bridges physical‑qubit mitigation and full fault‑tolerant quantum [...]

Quantum Motion promoted Dr. Anna Stockklauser to Chief Product Officer, expanding her oversight of global product strategy and hardware development as the company scales silicon spin‑qubit technology. Silicon Quantum Computing named John Hollister CFO, bringing two decades of financial leadership to support its atomic‑precision manufacturing roadmap and international expansion. Lawrence Semiconductor appointed Don Garrison as General Manager and COO to manage manufacturing, engineering, and quality across its Tempe cleanroom facilities. Pasqal added Roberto Mauro as CPO and [...]

Qtonic Quantum Corp unveiled QShield, a software‑only post‑quantum cryptography runtime that secures active Linux network connections. The solution creates encrypted overlay tunnels using NIST‑approved algorithms—ML‑KEM‑1024 for key exchange, ML‑DSA‑87 for authentication, and AES‑256‑GCM for payload encryption—without hardware appliances or pre‑shared keys. A 72‑hour AWS endurance test logged 4,107 continuous checks with zero failures, demonstrating reliability. QShield aligns with upcoming federal mandates, including CNSA 2.0 and Executive Order 14412, targeting data‑center interconnects and high‑value financial channels. [...]

Sectigo has introduced Quantum Ready™, an enterprise platform that marks the company’s entry into the Quantum Security Posture Management (QSPM) market. The solution functions as an operating framework and continuous discovery engine, scanning hybrid‑cloud, application and network environments to locate public‑key infrastructure certificates, symmetric and asymmetric keys, encryption algorithms and related dependencies. It automatically creates and updates a Cryptographic Bill of Materials (CBOM), replacing static risk assessments with a system of record. Built under Chief Product Officer [...]

USA Rare Earth, Pasqal, and Riven Systems announced a partnership to develop quantum machine learning (QML) models for separating heavy rare earth elements (REEs). Pasqal will supply neutral‑atom quantum processing units and QML algorithms, Riven will generate empirical training data through its autonomous chemistry lab, and USA Rare Earth will provide feedstock flowsheets and validate candidates at its Wheat Ridge, Colorado facility. The collaboration targets high‑selectivity extractants for dysprosium, terbium, and yttrium, aiming to reduce equipment, stages, [...]

A Department of Energy advisory panel has outlined a three‑phase plan to establish a national quantum computing user facility, contingent on fault‑tolerant systems demonstrating validated scientific value by 2028. The roadmap, presented by the DOE Office of Science’s Scientific Computing Advisory Committee, calls for 2026‑2028 “Quantum Grand Challenges” to benchmark progress through real scientific results rather than qubit counts. Milestones include 50‑100 logical qubits, 10,000‑100,000 logical operations, and 24‑hour end‑to‑end calculations with independent validation. The proposal envisions [...]
