Quantum distributed computing: potential and limitations

Abstract

The subject of this talk will be quantum distributed computing, i.e., distributed computing where the processors of the network can exchange quantum messages. In the first part of the talk I will survey recent results showing the power of quantum distributed algorithms. In the second part I will focus on my recent work (arXiv:2307.09444) showing that there is no distributed quantum advantage for approximate graph coloring. Finally, I will describe interesting and important open questions in quantum distributed computing.
