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,

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.
