    "abstract": "We present a way to realize a $n$-qubit controlled phase gate with\nsuperconducting quantum interference devices (SQUIDs) by coupling them to a\nsuperconducting resonator. In this proposal, the two logical states of a qubit\nare represented by the two lowest levels of a SQUID. An intermediate level of\neach SQUID is utilized to facilitate coherent control and manipulation of\nquantum states of the qubits. It is interesting to note that a $n$-qubit\ncontrolled phase gate can be achieved with $n$ SQUIDs by successively applying\na $\\pi /2$ Jaynes-Cummings pulse to each of the $n-1$ control SQUIDs before and\nafter a $\\pi$ Jaynes-Cummings pulse on the target SQUID.",
