#Hamiltonianlearning - Twitter Hashtag

I was intrigued about the problem of #HamiltonianLearning, and could not believe at first that it could be so difficult. It turned out that the true challenge lies in making the method robust to render in applicable in practical situations.

Importantly, we are also able to obtain tomographic information about those SPAM errors from the same data, crucial for the experimental applicability of #Hamiltonianlearning in dynamical quantum-quench experiments.

Over the last two years, we have substantially extended our work on #Hamiltonianlearning of #superconducting quantum chips. We have made substantial method development in the meantime, such as introducing the superresolution method TensorEsprit, to make it all actually work in practice for noisy data from @GoogleAI Sycamore chips, have added a great author (@fuksa_jonas) and have included a lot more data - to precisely learn and calibrate #analogquantumsimulators. We have now submitted our work, but will update our https://t.co/AZP6uRRcxm only after the xmas break.

At #QIP2023, with his usual brilliance, @RobertHuangHY tells the audience how to do #HamiltonianLearning with Heisenberg limited scaling.

This piece of work is particularly close to my heart. It presents a scalable and highly experimentally friendly method of #Hamiltonianlearning, by combining ideas of #tensornetworks and #machinelearning. It has been in the making for over two years. https://t.co/bsmoemfGt6
