A randomized quantum algorithm for statistical phase estimation
Kianna Wan, PhD Candidate, Stanford,

Joint AWS/IQIM Seminar

Abstract: Phase estimation is a quantum algorithm for measuring the eigenvalues of a Hamiltonian. We propose and rigorously analyse a randomized phase estimation algorithm with two distinctive features. First, our algorithm has complexity independent of the number of terms L in the Hamiltonian. Second, unlike previous L-independent approaches, such as those based on qDRIFT, all sources of error in our algorithm can be suppressed by collecting more data samples, without increasing the circuit depth. Joint work with Mario Berta & Earl Campbell.
