Rigetti and Purdue University Demonstrate Quantum Preconditioning Framework for Constrained Optimization

Rigetti Computing and Purdue University have published joint research extending Rigetti's quantum preconditioning framework to hard-constrained combinatorial optimization problems. The method uses two-point variable correlations extracted from shallow QAOA circuits to modify the problem's objective function before it is passed to a classical solver.

OutlookPlausible

Within two years, this framework could become a standard preprocessing step in Rigetti's cloud service, letting users submit constrained optimization problems, receive QAOA-derived correlation data, and warm-start commercial classical solvers.

One Qubit Can Beat One Bit: Quantum Advantage for Post-Training Quantization

A new arXiv preprint demonstrates that a quantum algorithm requiring only a single qubit can outperform the best known classical algorithm for post-training quantization of neural networks, achieving a provable advantage in terms of accuracy or efficiency.

OutlookPlausible

The algorithm is implemented on existing noisy quantum processors and integrated into cloud-based ML pipelines, enabling AI developers to offload quantization jobs for a measurable improvement in compression quality over purely classical methods within two years.
