Query: Quantum algorithm for preparing the ground state of a system via
  resonance transition   Preparing the ground state of a system is an important task in physics. We
propose a quantum algorithm for preparing the ground state of a physical system
that can be simulated on a quantum computer. The system is coupled to an
ancillary qubit, by introducing a resonance mechanism between the ancilla qubit
and the system, and combined with measurements performed on the ancilla qubit,
the system can be evolved to monotonically converge to its ground state through
an iterative procedure. We have simulated the application of this algorithm for
the Afflect-Kennedy-Lieb-Tasaki model, whose ground state can be used as
resource state in one-way quantum computation.
