Abstract：

Here　we　report　on　the　production　and　tomography　of　genuinely　entangled　Greenberger-Horne-Zeilinger　states　with　up　to　ten　qubits　connecting　to　a　bus　resonator　in　a　superconducting　circuit,　where　the　resonator-mediated　qubit-qubit　interactions　are　used　to　controllably　entangle　multiple　qubits　and　to　operate　on　different　pairs　of　qubits　in　parallel.　The　resulting　10-qubit　density　matrix　is　probed　by　quantum　state　tomography,　with　a　fidelity　of　0.668　+/-　0.025.　Our　results　demonstrate　the　largest　entanglement　created　so　far　in　solid-state　architectures　and　pave　the　way　to　large-scale　quantum　computation.
