摘要
In noisy intermediate-scale quantum (NISQ) computing, the scalability of a quantum processor unit (QPU) is limited by the number of qubits and their connectivity. To scale up quantum computing, one needs to employ entanglement-assisted distributed quantum computing (DQC) to implement a large quantum circuit over distributed small-size QPUs. Since entanglement is an expensive resource, we need to save the amount of entanglement consumed in DQC. In this talk, an entanglement-efficient DQC protocol called embedding-enhanced distributing will be introduced. With the help of graph theory, we develop an algorithm to find an entanglement-efficient strategy for distributing a given quantum circuit over two QPUs. The method will be then extended to modular DQC over multiple QPUs.
