[2] Together with Avinatan Hassidim and Seth Lloyd, he designed a quantum algorithm for linear systems of equations, which in some cases exhibits an exponential advantage over the best classical algorithms.
[3] The algorithm has wide application in quantum machine learning.
He is a steering committee member of Quantum Information Processing (QIP),[4] the largest annual conference in the field of quantum computing.
