Abstract

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 busparticle never contains information about the individual quantumstates of the particles, hence is information-free.
