Nearly Optimal Quantum Algorithm for Estimating Multiple Expectation Values
William J. Huggins, Kianna Wan, Jarrod McClean +3
Many quantum algorithms involve the evaluation of expectation values. Optimal strategies for estimating a single expectation value are known, requiring a number of state preparatio…

A randomized quantum algorithm for statistical phase estimation
Kianna Wan, Mario Berta, Earl T. Campbell
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 distincti…

New bounds on adaptive quantum metrology under Markovian noise
Kianna Wan, Robert Lasenby
We analyse the problem of estimating a scalar parameter that controls the Hamiltonian of a quantum system subject to Markovian noise. Specifically, we place bounds on the growt…
