Phase estimation with randomized Hamiltonians
Ian D. Kivlichan, Christopher E. Granade, Nathan Wiebe
Iterative phase estimation has long been used in quantum computing to estimate Hamiltonian eigenvalues. This is done by applying many repetitions of the same fundamental simulation…

Improved Fault-Tolerant Quantum Simulation of Condensed-Phase Correlated Electrons via Trotterization
Ian D. Kivlichan, Craig Gidney, Dominic W. Berry +9
Recent work has deployed linear combinations of unitaries techniques to reduce the cost of fault-tolerant quantum simulations of correlated electron models. Here, we show that one…
