Query: Geometric quantum computation and multi-qubit entanglement with
  superconducting charge qubits inside a cavity   We analyze a new scheme for quantum information processing, with
superconducting charge qubits coupled through a cavity mode, in which quantum
manipulations are insensitive to the state of the cavity. We illustrate how to
physically implement universal quantum computation as well as multi-qubit
entanglement based on unconventional geometric phase shifts in this scalable
solid-state system. Some quantum error-correcting codes can also be easily
constructed using the same technique. In view of the gate dependence on just
global geometric features and the insensitivity to the state of cavity modes,
the proposed quantum operations may result in high-fidelity quantum information
processing.
