We carry out our measurement-assisted scheme on an IBM Quantum processor and compare its performance with the purely unitary, sequential approach. Using the string order, entanglement spectrum, and quantum teleportation fidelity as metrics, we find that our measurement-assisted scheme outperforms its unitary counterpart. This work provides an efficient strategy to prepare a specific resource state, while more broadly serving as an experimental demonstration of the practical advantage afforded by measurement-based circuit depth reduction strategies on NISQ devices.
