Abstract

We propose a multi-qubit Bose-Einstein-condensate (BEC) trap as a platform for studies of quantum statistical phenomena in many-body interacting systems. In particular, it could facilitate testing atomic boson sampling of the excited-state occupations and its quantum advantage over classical computing in a full, controllable and clear way. Contrary to a linear interferometer enabling Gaussian boson sampling of non-interacting non-equilibrium photons, the BEC trap platform pertains to an interacting equilibrium many-body system of atoms. We discuss a basic model and the main features of such a multi-qubit BEC trap.

摘要

我们提出将多量子比特玻色-爱因斯坦凝聚体（BEC）阱作为研究多体相互作用系统中量子统计现象的平台。特别是，它能够以全面、可控且清晰的方式促进对激发态占据数的原子玻色子采样及其相对于经典计算的量子优势的测试。与能够对非相互作用的非平衡光子进行高斯玻色子采样的线性干涉仪不同，BEC阱平台属于原子的相互作用平衡多体系统。我们讨论了这种多量子比特BEC阱的基本模型和主要特征。
