Quantum Annealing for Heisenberg Spin Chains
G. P. Berman, V. N. Gorshkov, V. I. Tsifrinovich
We suggest using the method of quantum annealing for computing the ground state of the Heisenberg spin chains. Our initial Hamiltonian describes a spin system in a highly non-unifo…

Onset of Chaos in a Model of Quantum Computation
G. P. Berman, F. Borgonovi, F. M. Izrailev +1
We show that a magnetic field gradient can suppress the onset of quantum chaos in a nuclear spin chain quantum computer.
