Practical Graph States in Low Bandwidth, Noisy Quantum Networks

Abstract

Quantum graph states will be studied for both application use and network level (system level) use in near term Quantum Internet environments. Graph states are special forms of entangled quantum states, created by entangling a set of qubits pairwise in a pattern dictated by the machine or network's topology. A graph state can be used for both communication and computation by careful choice of single qubit gates and measurements. Applications of these graph states will be defined and evaluated for practicality of implementation in the near term, including required entanglement generation rates, fidelity and memory requirements. Network protocols for developing graph states within the network itself will be defined, and their efficiency, robustness and complexity relative to the minimal network protocols based entirely on Bell pairs. Analysis, simulation, and proof of principle experiments using a superconducting quantum computer will be conducted.
