基于门的量子计算机的可扩展基准

Scalable Benchmarks for Gate-Based Quantum Computers

Arjan Cornelissen, Johannes Bausch, András Gilyén

摘要:

在近期的“NISQ”时代,即噪声、中等规模、量子硬件及更高的时代,可靠地确定量子设备的质量变得越来越重要:用户需要能够将它们相互比较,并估计它们是否能够提前执行给定的任务。在这项工作中,我们开发并发布了一个先进的量子基准测试框架,以帮助评估当前量子设备的最新技术水平。我们的测试框架以硬件不可知的方式测量通用量子设备的性能,其指标旨在促进直观地了解哪种设备可能在给定任务上优于其他设备。这是通过六个结构化测试来实现的,这些测试允许对设备的比较进行即时的视觉评估。每个测试的设计都考虑到了可扩展性,使得这个框架不仅适用于测试当今量子设备的性能,而且适用于在可预见的未来发布的量子设备的性能。这一系列测试是由现实生活中的场景激发的,因此强调了量子设备的各种相关特性之间的相互作用,例如量子比特计数,连接性以及门和测量保真度。我们提出了来自IBM,Rigetti和IonQ的21种不同量子设备的基准测试结果。

英文摘要:

In the near-term "NISQ"-era of noisy, intermediate-scale, quantum hardware and beyond, reliably determining the quality of quantum devices becomes increasingly important: users need to be able to compare them with one another, and make an estimate whether they are capable of performing a given task ahead of time. In this work, we develop and release an advanced quantum benchmarking framework in order to help assess the state of the art of current quantum devices. Our testing framework measures the performance of universal quantum devices in a hardware-agnostic way, with metrics that are aimed to facilitate an intuitive understanding of which device is likely to outperform others on a given task. This is achieved through six structured tests that allow for an immediate, visual assessment of how devices compare. Each test is designed with scalability in mind, making this framework not only suitable for testing the performance of present-day quantum devices, but also of those released in the foreseeable future. The series of tests are motivated by real-life scenarios, and therefore emphasise the interplay between various relevant characteristics of quantum devices, such as qubit count, connectivity, and gate and measurement fidelity. We present the benchmark results of twenty-one different quantum devices from IBM, Rigetti and IonQ.
