Quantum Computing Digest — 2022

In 2022, quantum computing transitioned from speculative hype to pressing operational risks, forcing organizations to address immediate challenges in security, hardware, software, policy, fragile supply chains, and workforce shortages. Post-quantum cryptography advanced from theory to active planning and procurement, as delays now posed tangible security and compliance threats, while overhyped hybrid quantum-classical systems faced increased skepticism. Ultimately, the year highlighted that quantum adoption will hinge far more on mastering today’s engineering, infrastructure, and execution risks than on awaiting major theoretical breakthroughs.

Quantum Enhanced Coherent Ising Machines Accelerated by NTT Research

NTT Research and Tohoku University have launched a collaboration to accelerate quantum enhanced Coherent Ising Machines (CIM) on high-performance computing platforms. Their paper in Quantum Science and Technology reveals that single-photon CIMs outperform conventional models, converting fragile quantum entanglement into strong classical correlations. The teams will next optimize kernels, scale to 100 million spins, and pursue a physical implementation of Cyber CIM for industrial optimization.
