2023/3/28
High-dimensional sampling problems are ubiquitous in statistics, operations research, machine learning, etc. In this talk, I will introduce quantum algorithms for two important problems in high-dimens...
Electrons and their behavior pose fascinating questions for quantum physicists, and recent innovations in sources, instruments and facilities allow researchers to potentially access even more of the i...
Collaborative research is as fundamental to life at Cornell as hourly chimes, Big Red hockey and Slope Day. It’s a commitment the university takes seriously – and now it’s expanding.
Fumbling to find flashlights during blackouts may soon be a distant memory, as quantum computing and artificial intelligence could learn to decipher an electric grid’s problematic quirks and solve sys...
An interdisciplinary team of Cornell and Harvard University researchers developed a machine learning tool to parse quantum matter and make crucial distinctions in the data, an approach that will help ...
In Quantum supremacy using a programmable superconducting processor, in the Oct. 24 issue of the journal Nature, a team of researchers led by Google present evidence that their quantum computer has ac...
