Suppression of quantum chaos in a quantum computer hardware
arXiv:cond-mat/0510392 · doi:10.1103/PhysRevE.74.026208
Abstract
We present numerical and analytical studies of a quantum computer proposed by the Yamamoto group in Phys. Rev. Lett. 89, 017901 (2002). The stable and quantum chaos regimes in the quantum computer hardware are identified as a function of magnetic field gradient and dipole-dipole couplings between qubits on a square lattice. It is shown that a strong magnetic field gradient leads to suppression of quantum chaos.
