Cornell University researchers, led by Professor Karan Mehta, used Nullspace ES to simulate electrostatic fields for a chip‑scale ion trap, enabling the first experimental demonstration of standing‑wave electromagnetically‑induced‑transparency (EIT) cooling for trapped ions. The simulations produced baseline voltage sets for axial confinement, radial mode rotation, and sub‑micron ion positioning. The new cooling method achieved higher rates, covered more motional modes, and reached lower final phonon occupation numbers than conventional running‑wave techniques.

SEALSQ Corp, WISeKey International Holding, and the Canton of Jura signed a memorandum of understanding to create a Post‑Quantum Semiconductor and Cybersecurity Center in the Swiss canton. The project will invest roughly CHF 40‑60 million over six years, focusing on the QS7001 Quantum Shield and related secure firmware personalization, testing, and certification. The initiative aims to generate about 40 jobs in two years, expanding to over 250 by year eight, with a majority of positions filled by local residents. [...]

D‑Wave Quantum Inc. announced the appointment of Bernard Gavgani, former group chief information officer of BNP Paribas, to its Board of Directors and Cybersecurity Committee. Gavgani, who now serves as senior advisor for technology and innovation to BNP Paribas executive management, will join the board in a personal capacity. His résumé includes overseeing global technology strategy, AI governance, cybersecurity, and large‑scale operational transformation at the French banking giant. D‑Wave highlighted his experience in integrating emerging technologies within regulated enterprises and [...]

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. [...]
