Information Free Quantum Bus for Generating Stabiliser States

  • Published:
Quantum Information Processing Aims and scope Submit manuscript

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.
