    "abstract": "Going beyond the entanglement of microscopic objects (such as photons, spins,\nand ions), here we propose an efficient approach to produce and control the\nquantum entanglement of three macroscopic coupled superconducting qubits. By\nconditionally rotating, one by one, selected Josephson charge qubits, we show\nthat their Greenberger-Horne-Zeilinger (GHZ) entangled states can be\ndeterministically generated. The existence of GHZ correlations between these\nqubits could be experimentally demonstrated by effective single-qubit\noperations followed by high-fidelity single-shot readouts. The possibility of\nusing the prepared GHZ correlations to test the macroscopic conflict between\nthe noncommutativity of quantum mechanics and the commutativity of classical\nphysics is also discussed.",
