Hi everyone, 

this is a reminder that tomorrow,  July 1st, Prof. Apoorva Patel is visiting the group for one day. Prof. Patel will give a talk at 3pm on the optimization of quantum Hamiltonian evolution.

Title: Optimisation of Quantum Hamiltonian Evolution
Speaker: Apoorva Patel
         Centre for High Energy Physics
         Indian Institute of Science, Bangalore-560012
Abstract:
Given a quantum Hamiltonian and its evolution time, the corresponding
unitary evolution operator can be constructed in many different ways,
corresponding to different trajectories between the desired end-points.
A choice among these trajectories can then be made to obtain the best
computational complexity and control over errors. It is shown how a
construction based on Grover's algorithm scales linearly in time and
only logarithmically in error bound, and is clearly superior to the
scheme based on straightforward application of the Lie-Trotter formula.
