论文摘要
在本文中，我们描述了构建通用量子计算机的最有希望的平台之一，该平台由$ n $ n $ ions的链组成，被困在谐波潜力中，其内部状态可作为Qubits起作用，并与链的集体振动模式耦合。从这样的耦合，可以在链的不同离子之间建立相互作用，即Qubit-Qubit-Qubit相互作用，这些相互作用与离子上的单个操作一起，允许构建1990年代CIRAC和Zoller首次提出的量子计算机[Phys [Phys]。莱特牧师。 74，4091（1995）]。在这里，我们从涉及将离子捕获电磁电位的物理学到产生通用的逻辑门所需的汉密尔顿工程，这是执行更复杂的量子算法的基础。最后，我们介绍了被困离子系统中量子计算的现行状态，强调了使用IONQ和AQTION等建筑的公司和政府项目的最新进展。
In this paper we describe one of the most promising platforms for the construction of a universal quantum computer, which consists of a chain of $N$ ions trapped in a harmonic potential, whose internal states work out as qubits, and are coupled to collective vibrational modes of the chain. From such coupling, it is possible to build interactions between different ions of the chain, that is, qubit-qubit interactions that, together with individual operations on the ions, allow building a quantum computer as first proposed by Cirac and Zoller in the 1990s [Phys. Rev. Lett. 74, 4091 (1995)]. Here we discuss from the physics involved in trapping ions in electromagnetic potentials to the Hamiltonian engineering needed to generate a universal set of logic gates, fundamental for the execution of more complex quantum algorithms. Finally, we present the current state of the art of quantum computing in trapped ion systems, highlighting recent advances made by companies and government projects that use such architecture, such as IonQ and AQTION.
