Fast simulation of a quantum phase transition in an ion-trap realizable unitary map
John Paul Barjaktarevič, Gerard J Milburn, Ross H. McKenzie · Physical Review A · 2005
We show that a specific implementation of a unitary map on multiple qubits in an ion trap is physically equivalent to a Hamiltonian evolution that belongs to the same universality class as the transverse Ising Hamiltonian. We suggest experimental signatures, and present numerical simulations for the case of four qubits.
