Title - Stabilizer quantum error correction toolbox for superconducting qubits

Abstract - 

Superconducting circuits composed of Josephson Junctions and resonators form an interesting architecture for quantum information processing. The coherence times of these systems are approaching the predicted requirements for fault-tolerant quantum computation. Rudimentary quantum error correction (QEC) has recently been achieved in such a system [1].  Realization of topological protection and QEC based on stabilizer codes will require protocols for QND measurement of multi-qubit Pauli operators on
arbitrary selected subsets of qubits.  Initial progress towards this goal has been achieved with four-qubit stabilizer pumping in a trapped ion system [2]. I will present a general protocol for stabilizer measurement in a system of $N$ superconducting qubits dispersively coupled to a single mode of a resonator.
