Can someone explain to me how to build a quantum circuit representing the Ising Model? I just want to understand how to represent the Ising Model for the purposes of quantum state label classification.

  • $\begingroup$ What don't you understand about the paper I linked? $\endgroup$ Apr 22, 2019 at 4:08
  • $\begingroup$ For example, if I have a U(\theta), where U is a resulting unitary matrix of a series of unitaries with distinct theta parameters, I want to understand what is the difference between measuring at every wire in the circuit and measure the energy vs measuring the wire of the line-out qubit. And for that matter, why Pauli-Y is important in measuring in the line-out qubit. In short: I am trying to understand quantum variation algorithms using Cirq and how to use the problem (Ising model) described as a circuit to find minimal energies? $\endgroup$ Apr 22, 2019 at 18:49

    $\begingroup$ Which variant of the Ising model are you wanting? one-dimensional transverse Ising model? $\endgroup$
