    "abstract": "We propose a scalable method on the basis of nth-order coupling operators to\nconstruct f-dependent phase transformations in the n-qubit modified\nDeutsch-Jozsa (D-J) quantum algorithm. The novel n-qubit entangling\ntransformations are easily implemented via J-couplings between neighboring\nspins. The seven-qubit modified D-J quantum algorithm and seventh-order\ncoupling transformations are then experimentally demonstrated with liquid state\nnuclear magnetic resonance (NMR) techniques. The method may offer the\npossibility of creating generally entangled states of n qubits and simulating\nn-body interactions on n-qubit NMR quantum computers.",
