Efficient dynamics simulation of spin systems on a classical computer is limited by the exponential growth of Hilbert space with the number of interacting spins. . The scalability of the problem reduces from exponential to linear when implemented on a quantum computer, which allows to expand the model size, with the limitation being only the number of qubits. The Heisenberg model is one of the simplest models that describes the behavior of spin systems and has been previously implemented on the quantum hardware for an XY model[SV1] . To make such quantum simulations more resilient to noise, the depth of quantum circuit can be reduced using the Yang-Baxter equation (YBE), which has been done before for the one-dimensional XY-Heisenberg model. We investigate spin dynamics in a Cu3(saltatris(2-hydroxybenzylidene)triaminoguanidine)(pyridine)6 complex, focusing on the three spin-1/2 Cu(II) ions. We obtain the antiferromagnetic exchange constant from the electronic structure calculations and map it on the XXX-Heisenberg model. We solve the XXX-Heisenberg Hamiltonian in time-dependent magnetic field using 1) traditional classical algorithm, 2) the YBE quantum algorithm on a quantum simulator and 3) the YBE algorithm on a multi-qubit quantum device.
