摘要

一个被限制在光学偶极子阱中的原子是一个很有希望成为量子比特的候选者。分析这些被困原子的时间响应，使我们能够估计量子计算机的运行速度。本文模拟了在交叉激光束形成的光学偶极子阱中的原子，并进一步研究了这种受限原子的光电离时间延迟。我们研究稀有气体原子，如Ne (Z = 10)、Ar (Z = 18)、Kr (Z = 36)和Xe (Z = 54)。利用x射线自由电子激光器(XFEL)认为原子被限制在光学偶极子阱中。本文的工作表明，被困原子的光离延迟与自由原子的光离延迟是不同的。这一分析提醒我们，在讨论量子计算的速度时，也必须考虑到被困环境中原子的时间响应。

Temporal Response of Atoms Trapped in an Optical Dipole Trap: A Primer on Quantum Computing Speed

An atom confined in an optical dipole trap is a promising candidate for a qubit. Analyzing the temporal response of such trapped atoms enables us to estimate the speed at which quantum computers operate. The present work models an atom in an optical dipole trap formed using crossed laser beams and further examines the photoionization time delay from such confined atoms. We study noble gas atoms, such as Ne (Z = 10), Ar (Z = 18), Kr (Z = 36), and Xe (Z = 54). The atoms are considered to be confined in an optical dipole trap using X-ray Free Electron Lasers (XFEL). The present work shows that the photoionization time delay of the trapped atoms is different compared with that of the free atoms. This analysis alerts us that while talking about the speed of quantum computing, the temporal response of the atoms in the trapped environment must also be accounted for.

期刊介绍： Atoms (ISSN 2218-2004) is an international and cross-disciplinary scholarly journal of scientific studies related to all aspects of the atom. It publishes reviews, regular research papers, and communications; there is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental and/or methodical details must be provided for research articles. There are, in addition, unique features of this journal: -manuscripts regarding research proposals and research ideas will be particularly welcomed. -computed data, program listings, and files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. Scopes: -experimental and theoretical atomic, molecular, and nuclear physics, chemical physics -the study of atoms, molecules, nuclei and their interactions and constituents (protons, neutrons, and electrons) -quantum theory, applications and foundations -microparticles, clusters -exotic systems (muons, quarks, anti-matter) -atomic, molecular, and nuclear spectroscopy and collisions -nuclear energy (fusion and fission), radioactive decay -nuclear magnetic resonance (NMR) and electron spin resonance (ESR), hyperfine interactions -orbitals, valence and bonding behavior -atomic and molecular properties (energy levels, radiative properties, magnetic moments, collisional data) and photon interactions
