NUS Spintronic Processors Deliver 3.2-Fold Speedup and 58% Energy Savings for Optimization Tasks

Researchers at the National University of Singapore have developed probabilistic spintronic processors built from magnetic tunnel junctions. These processors achieved a 3.2-fold speedup and 58.3 percent energy savings compared with conventional CPUs on quadratic assignment problems. The hardware also outperformed commercial D-Wave quantum annealers by consistently returning feasible, high-quality solutions as problem size increased. Cluster parallel updates and simulated quantum annealing techniques delivered further gains of up to 10-fold acceleration and 20-fold better solution quality.

Quantum Computing Digest — 2021​

By 2021, quantum computing was no longer defined solely by experimental promise, but by growing demands for operational readiness. Across hardware, software, networking, and security, the ecosystem began organizing around scalable engineering and enterprise integration. Hybrid workflows, cloud delivery, and crypto-agile security planning progressed into early deployment. While fault-tolerant systems remained a longer-term goal, the year materially strengthened the infrastructure required to manage both opportunity and risk.
