Maximizing concave piecewise affine functions on the unitary group
Abstract
We show that a convex relaxation, introduced by Sridharan, McEneaney, Gu and James to approximate the value function of an optimal control
problem arising from quantum gate synthesis, is exact. This relaxation applies
to the maximization of a class of concave piecewise affine functions over the
unitary group
