| الوصف: | We address the variational preparation of the Thermofield Double state (TFD) as the ground state of a suitably engineered Hamiltonian acting on the doubled Hilbert space. Through the use of the entanglement forging ansatz, we propose a solution that involves only circuits of width $N$. We illustrate the method with generic fermionic hamiltonians. The free fermion case can be solved in closed form, and yields a warm start state for the variational circuits whenever interactions are present. Comment: 12 pages, 7 figures |
