离子阱量子计算规模化的研究进展
Research progress of ion trap quantum computing
摘要
Abstract
Ion trap is one of the leading physical platforms to implement quantum computation.Currently,high-fidelity elementary quantum operations above the fault-tolerant threshold,including state preparation,measurement and universal gates,have been demonstrated for tens of ionic qubits.One important future research direction is to further enlarge the qubit number to the scale required for solving practical problems while maintaining the high performance of individual qubits.This paper introduces the current mainstream schemes for scalable ion trap quantum computation like quantum charge-coupled device(QCCD)and ion-photon quantum network,and describes the main limiting factors in current research.Then we further explore new schemes to scale up the qubit number like two-dimensional ion crystals and dual-type qubit,and discuss the future research directions.关键词
