Shorter width truncated Taylor series for Hamiltonian dynamics simulations
Michelle Wynne Sze, David Zsolt Manrique, David Muñoz Ramo +1
As established in the seminal work by Berry et al.[1], expanding the time evolution operator using truncated Taylor series (up to some order ) makes a good candidate for simulat…

Hamiltonian dynamics simulation using linear combination of unitaries on an ion trap quantum computer
Michelle Wynne Sze, Yao Tang, Silas Dilkes +3
The linear combination of unitaries (LCU) method has proven to scale better than existing product formulas in simulating long time Hamiltonian dynamics. However, given the number o…
