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)[itex]\sum\sigma^{(i)}_{x}[/itex]
(2) Hf=(-1/2)[itex]\sumhi\sigma^{(i)}_{z}[/itex]+(1/2)[itex]\sumJ_{ij}\sigma^{(i)}_{z}\sigma^{(j)}_{z}[/itex]
(3) Hs(t)=(1-s(t))Hi+s(t)Hf
and in Hf must i>j in the second summation, and hi and Jij from{-1,0,1}. please help me how can I diagonalize the Hamiltonian (3) with (1) and (2) with random instances for 20 qubits by randomly choosing hi and Jij. mostly I have problem with multiplying two sigmas in Hf.
Thanks a lot.
