Description:
Author(s): A. Yu. Smirnov and M. H. Amin We study a system of qubits that are coupled to each other via only one degree of freedom, represented, e.g., by σ z operators. We prove that if, by changing the Hamiltonian parameters, a nondegenerate ground state of the system is continuously transformed in such a way that the expectation values of... [Phys. Rev.
