论文摘要

全息原理及其在ADS/CFT对应中的实现导致一般相对性和量子信息之间的意外联系。这为研究量子重力模型的各个方面奠定了阶段,否则难以访问,在桌上量子计算实验中。最近的作品设计了一种特殊的传送协议,该协议实现了令人惊讶的沟通现象,最自然地通过可穿越的虫洞的物理学来解释。在这项工作中,我们基于该协议对最先进的量子计算机进行了量子实验。目标量子处理单元(QPU)包括Quantinuum的捕获 - 离子系统模型H1-1和五个IBM各种体系结构的IBM超导QPU,并具有公共和优质用户访问权限。我们报告了这些QPU的观察到的传送信号,其中最佳的传送信号达到了80%的理论预测。我们概述了实施过程中面临的实验挑战,以及对工作导致的量子动态的新理论见解。我们还开发了QGLAB - 一种开源的端到端软件解决方案,可促进对Qiskit和Tket SDKS支持的最先进和新兴QPU进行虫洞启发的传送实验。我们将我们的研究和可交付成果视为实现更复杂的实验的早期实际一步,以间接探测实验室的量子重力。

The holographic principle and its realization in the AdS/CFT correspondence led to unexpected connections between general relativity and quantum information. This set the stage for studying aspects of quantum gravity models, which are otherwise difficult to access, in table-top quantum-computational experiments. Recent works have designed a special teleportation protocol that realizes a surprising communication phenomenon most naturally explained by the physics of a traversable wormhole. In this work, we have carried out quantum experiments based on this protocol on state-of-the-art quantum computers. The target quantum processing units (QPUs) included the Quantinuum's trapped-ion System Model H1-1 and five IBM superconducting QPUs of various architectures, with public and premium user access. We report the observed teleportation signals from these QPUs with the best one reaching 80% of theoretical predictions. We outline the experimental challenges we have faced in the course of implementation, as well as the new theoretical insights into quantum dynamics the work has led to. We also developed QGLab -- an open-source end-to-end software solution that facilitates conducting the wormhole-inspired teleportation experiments on state-of-the-art and emergent generations of QPUs supported by the Qiskit and tket SDKs. We consider our study and deliverables as an early practical step towards the realization of more complex experiments for the indirect probing of quantum gravity in the lab.
