“…where ⊗ denote a tensor product, A † is the adjoin of A, and P is the qubit pointer [28,29]. If we simulate the Hamiltonian H in ( 27) with the initial state |z⟩ |z⟩ |0⟩ P in a quantum computer, the quantum system will evolve in accordance with H for a time step 𝜖 following (19) to reach the following steady-state |Ψ⟩ [21] (see Appendix A.2):…”

“…We follow the steps of Ref. [17], which treated the d = 2 case. We choose the initial spin state to maximize the entanglement which will develop with the ancilla qubit system.…”

“…This section comprises a generalization of the Ref. [17] treatment to arbitrary nonbinary spins. It is remarkable that the spin-ancilla system is again described completely by three commuting observables -two for collapse properties and one for the superposition property.…”

“…There are, of course, many other suggested solutions to the measurement problem [10,11] with some of these distinct from those mentioned above and some novel modifications [12,13,14,15,16]. Here, we resolve the measurement problem by postulating the existence of unique phase-sets that are tied to the eigenvectors of a Hamiltonian.…”
