hello i encountered for relaxation term in studing "role of single qubit decoherence time in adiabatic quantum computation": relaxation rate=n(Mx^2+Mz^2)s(w10); n=number of qubits s(w10) is summetrized spectral density ofthe baths Mx=((1/n)\sum\(sigma x^{i}_{1,0})^2))^(1/2)...

excuse me,our Hamiltonian is: Hi=(-1/2)\sum\sigma^{(i)}_{x} Hf=(-1/2)\sum\sigma^{(i)}_{z}hi +(1/2)\sum\sigma^{(i)}_{z}*sigma^{(j)}_{z}Jij Moreover if we want diagonalize hs(t) for two first states(i.e. 0 &1 states), what shall we do? thank you very much.

Hello,I am doing a research related to Ising Model in m research, evolution of a multi-qubit Ising system with the initial and final Hamiltonian is given by: (1) Hi=(-1/2)\sum\sigma^{(i)}_{x} (2) Hf=(-1/2)\sumhi\sigma^{(i)}_{z}+(1/2)\sumJ_{ij}\sigma^{(i)}_{z}\sigma^{(j)}_{z} (3)...
