Fig. 9: Adaptive pulse sequences for LiH molecule.
From: Gate-free state preparation for fast variational quantum eigensolver simulations
Square pulse shapes obtained at each adaptive step, starting from one time window and adaptively dividing the time window up to five-segments. The accuracy increases with each division of the pulse. Pulse shapes are shown for the pulses on a qubit 1, b qubit 2, c qubit 3, d qubit 4.
