High Fidelity Noise-Tolerant State Preparation of a Heisenberg spin-1/2
  Hamiltonian for the Kagome Lattice on a 16 Qubit Quantum Computer
This work describes a method to prepare the quantum state of the Heisenberg
spin-1/2 Hamiltonian for the Kagome Lattice in an IBM 16 qubit quantum computer
with a fidelity below 1% of the ground state computed via a classical
Eigen-solver. Furthermore, this solution has a very high noise tolerance (or
overall success rate above 98%). With industrious care taken to deal with the
persistent noise inherent to current quantum computers; we show that our
solution, when run, multiple times achieves a very high probability of success
and high fidelity. We take this work a step further by including efficient
scalability or the ability to run on any qubit size quantum computer. The
platform used in this experiment is IBM's 16 qubit Gudalupe processor using the
Variational Quantum Eigensolver (VQE).
