Hi all,
Ian will speak at the group meeting tomorrow. His title and abstract can be found below.
We will meet in SS571 at 2:30pm. Please be on time. If you'd like to connect via
Skype, let me know.
Best,
Riley

Title: Phase estimation with randomized Hamiltonians
Abstract: Phase estimation is commonly used in quantum simulation to estimate Hamiltonian
eigenenergies. However, not all terms in the Hamiltonian contribute equally to the energy.
Motivated by this, I will discuss theoretical and numerical work allowing us to reduce the
cost of phase estimation by changing how frequently different Hamiltonian terms are
simulated. The same approach also allows us to better understand the errors in different
simulation approaches.
