USA Rare Earth, Pasqal and Riven Systems plan to use quantum machine learning to find new rare earth extractants. We look at the hundreds of solvent-extraction stages, prior classical AI results, and the three tests a quantum model must pass.
A close look at NVIDIA's CUDA-Q Logical based on its papers and official documentation. Examining what the P0–P4 stages, the four-tier resource estimates, QUOPS, and the 150,000-qubit figure mean—and where their limits lie.
Researchers at Zhejiang University, Tsinghua University and others ran proof operations for a square theorem and a 1978 International Mathematical Olympiad problem on a superconducting quantum circuit. We trace how the work was split with classical computing, what the experiment shows, and what remains unproven about quantum advantage.
Fujitsu's newly released OpenQARP v0.1.0 separates quantum circuits, measurement targets, and execution engines, making research algorithms reusable across environments. Drawing on public materials, this piece examines what the design means and the limits of evidence so far—no results yet confirm quantum advantage or outside-developer adoption.
Fujitsu unveiled a single-module quantum prototype that integrates tin-vacancy (SnV) centers into a photonic circuit. This article separates the 2027 optical-connection goal from the 2035 fiscal-year target to clarify where the technology stands and what performance data remain undisclosed.
IonQ's 256-qubit Superion 256 links electronic control with semiconductor fabrication. Beyond QPU manufacturing and ion trapping, questions remain about integrated performance, yield, and customer delivery.
Germany's Forschungszentrum Jülich and startup eleQtron have activated JION, an ion-trap quantum computer controlled entirely by microwaves. The system is now fully integrated with Europe's leading HPC infrastructure for hybrid computing operations.
A Quantinuum research team used an ion-trap quantum computer to surpass a mathematically proven upper bound on classical computation. Using complement sampling, which does not rely on unproven computational complexity assumptions, the team opened a new path toward efficient and rigorous verification of hardware's non-classical behavior.
NEC, which demonstrated the world's first superconducting qubit in 1999, halted development of physical quantum computers at the end of March 2026. In December 2022 it told a Japanese Cabinet Office panel it was aiming beyond 1,000 qubits. The most it ever publicly demonstrated was 8. This piece examines the gap between NEC's own roadmap and what it actually achieved before pulling out.
A quantum router experiment using 10 qubits on China's superconducting quantum processor 'Wukong' recorded a single-unit transmission efficiency of 98%. But fidelity dropped to the 82% range in a two-layer network, and the paper itself acknowledges that the chip's structure caps scalability at five layers.
