Optimal distributed multiparameter estimation in noisy environments

2023 · arXiv (Cornell University)

We consider the task of multiple parameter estimation in the presence of strong correlated noise with a network of distributed sensors. We study how to find and improve noise-insensitive strategies. We show that sequentially probing …

An exponentially-growing family of universal quantum circuits

2023 · Machine Learning Science and Technology

Abstract Quantum machine learning has become an area of growing interest but has certain theoretical and hardware-specific limitations. Notably, the problem of vanishing gradients, or barren plateaus, renders the training impossible for circuits with high …
