    "abstract": "We describe an assembly of N superconducting qubits contained in a\nsingle-mode cavity. In the dispersive regime, the correlation between the\ncavity field and each qubit results in an effective interaction between qubits\nthat can be used to dynamically generate maximally entangled states. With only\ncollective manipulations, we show how to create maximally entangled quantum\nstates and how to use these states to reach the Heisenberg limit in the\ndetermination of the qubit bias control parameter (gate charge for charge\nqubits, external magnetic flux for rf-SQUIDs).",
