@article{Devitt2007InformationFQ, title={Information Free Quantum Bus for Generating Stabiliser States}, author={Simon J. Devitt and Andrew D. Greentree and Lloyd C. L. Hollenberg}, journal={Quantum Information Processing}, year={2007}, volume={6}, pages={229-242} }

Efficient generation of spatially delocalised entangledstates is at the heart of quantum information science. Generally,flying qubits are proposed for long range entangling interactions,however here we introduce a bus-mediated alternative for this task.Our scheme permits efficient and flexible generation ofdeterministic two-qubit operator measurements and has links to theimportant concepts of mode-entanglement and repeat-until-successprotocols. Importantly, unlike flying qubit protocols, our…
