用于量子计算的天然和人造原子

Natural and artificial atoms for quantum computation

Iulia Buluta, Sahel Ashhab, Franco Nori

摘要:

使用自然和人造原子作为量子比特,实现量子计算已经取得了显着进展。本文简要概述了不同类型量子比特的现状。一方面,自然原子(如中性原子和离子)具有较长的相干时间,可以存储在大阵列中,提供理想的“量子存储器”。另一方面,人造原子(如超导电路或半导体量子点)具有定制设计功能的优势,可以用作“量子处理单元”。自然和人造原子可以相互耦合,也可以与光子进行长距离通信。由天然/人造原子和光子制成的混合设备可能为量子计算机提供下一代设计。

英文摘要:

Remarkable progress towards realizing quantum computation has been achieved using natural and artificial atoms as qubits. This article presents a brief overview of the current status of different types of qubits. On the one hand, natural atoms (such as neutral atoms and ions) have long coherence times, and could be stored in large arrays, providing ideal "quantum memories". On the other hand, artificial atoms (such as superconducting circuits or semiconductor quantum dots) have the advantage of custom-designed features and could be used as "quantum processing units". Natural and artificial atoms can be coupled with each other and can also be interfaced with photons for long-distance communications. Hybrid devices made of natural/artificial atoms and photons may provide the next-generation design for quantum computers.
