NVIDIA Launches Open-Source AI Models to Accelerate Quantum Error Correction
NVIDIA has introduced “Ising,” its first family of open AI models for building fault-tolerant quantum computers. The Ising Decoding models use 3D CNN-based architectures to decode quantum errors in real time, with the flagship ColorCode 1 Fast model cutting logical error rates by up to 347x and running 7.3x faster than the leading open-source decoder, Chromobius. NVIDIA is releasing the model weights, training recipes, and benchmarks openly for researchers to adapt to their own quantum processors.

Classic McEliece Becomes First Post-Quantum Algorithm to Achieve Global ISO Standardization
UK-based Post-Quantum announced that its Classic McEliece algorithm, built on Robert McEliece’s 1978 code-based cryptosystem, has been formally integrated into ISO/IEC 18033-2, making it the first post-quantum cryptography algorithm to reach ISO standardization under that specification. The recognition gives organizations across ISO’s 177 member states an interoperable framework to defend against “harvest now, decrypt later” attacks, building on existing recommendations from Germany’s BSI and the Dutch NCSC.

Quantum eMotion’s SecureKey Module Enters NIST Testing for FIPS 140-3
Quantum eMotion’s SecureKey Cryptographic Module has been designated “Implementation Under Test” on NIST’s Cryptographic Module Validation Program registry, a key step toward formal FIPS 140-3 certification. The module, built around a “memory-less” design intended to prevent key exposure, is being evaluated in partnership with an accredited testing laboratory as part of Quantum eMotion’s Sentry-Q platform.

Quantum Networking Startup Arq Raises $1.4M to Build Toward the Quantum Internet
Arq, founded in 2025 by quantum scientists Samuele Grandi and Emanuele Distante, has raised a $1.4 million pre-seed round led by Ground State Ventures, with Big Sur Ventures also participating. The company is developing a multiplexed quantum repeater based on rare-earth-doped crystal quantum memories and photon-pair sources, aimed at connecting quantum computers over long distances more reliably than current approaches. The funding will build out a new lab focused on reproducibility of its quantum memory devices.

Theorists Prove Quantum Proofs Can Do What Classical Ones Cannot
Mark Zhandry, John Bostanci, Jonas Haferkamp, and Chinmay Nirkhe have shown, via a problem they call “spectral forrelation,” that some computational proofs are only possible with a quantum witness — no classical certificate can substitute. The result, recognized at the 2026 Symposium on Theory of Computing, establishes in a relativized setting that quantum verification (QMA) is strictly more powerful than classical-witness verification (QCMA), sharpening theorists’ understanding of where quantum advantage is provably real.
