Pasqal has published new research exploring the performance of its neutral atom quantum processors on combinatorial optimization problems, with a focus on creating realistic, classically hard benchmarks. Recognizing the limitations of earlier speedup claims based on oversimplified problems, the study emphasizes the need for rigorous benchmarking against classical solvers used in production. The team applied its methodology to the Maximum Independent Set (MIS) problem on unit-disk graphs—a challenge that appears in fields like wireless networks and molecular design. This research is the first in a three-part series intended to clarify when and how quantum hardware can achieve a practical advantage. The [...]

QC Design has announced a major performance breakthrough in its quantum fault-tolerance design software, Plaquette, through integration with NVIDIA’s cuQuantum SDK. The update leverages cuTensorNet to enable high-performance, full-state simulations of fault-tolerant quantum circuits. As a result, Plaquette can now simulate over 400 qubits on a single NVIDIA RTX 4000 Ada GPU with 20GB memory—an improvement over current CPU-based Monte Carlo simulators, which typically simulate only ~60 qubits using 120GB of RAM. The GPU-accelerated simulations also deliver significant performance gains. Plaquette achieves at least a 180x speedup in sampling throughput for 60-qubit circuits compared to CPU-based alternatives, making it viable to [...]

IonQ and Ansys have reported a practical instance of quantum computing outperforming classical computation in a real-world engineering workflow. The demonstration involved running a fluid dynamics simulation related to blood pump design using a hybrid quantum-classical approach on IonQ’s production system. Compared to a fully classical implementation, the quantum-assisted workflow achieved a 12% improvement in processing performance, marking one of the first published cases of quantum speedup in a commercially relevant application. The experiment utilized IonQ Forte, IonQ’s latest trapped-ion quantum system, to assist with solving a graph optimization subroutine in the Ansys LS-DYNA software. The quantum-enhanced simulation processed a model [...]

Delft Circuits has introduced a turnkey High-Density Input/Output (HD I/O) system designed to overcome one of the key bottlenecks in utility-scale quantum computing: cryogenic wiring scalability. Traditional coaxial cabling requires a linear increase in cryostat wiring as qubit counts grow, leading to thermal, spatial, and integration limitations. Delft’s new system delivers 256 control channels per module—a significant increase over the 168-channel limit of high-density coax alternatives—without requiring larger refrigeration infrastructure. Its modular loader architecture enables 32-channel increments, allowing researchers to scale I/O capacity in step with qubit demands while minimizing cost, space, and complexity. The HD I/O system is compatible with [...]
