NISQ时代量子计算机的近似可逆电路
Approximate Reversible Circuits for NISQ-Era Quantum Computers
摘要：
量子电路的综合方法通常旨在最小化线路或门“或”门的数量。考虑到物理实现中对这些逻辑资源的严格限制，我们建议从根本上看待这个问题：给定噪声门和固定数量的行，我们如何使用它们来尽可能精确地执行计算？在本文中，我们可以部署近似电路的计算资源有限。在QC模拟器上进行实验，我们表明，在噪声的影响下，近似电路可以有较低的错误率比确切的电路。
英文摘要：
The synthesis approaches for quantum circuits typically aim at minimizing the number of lines or gates. Given the tight restrictions on those logical resources in physical implementations, we propose to view the problem fundamentally different: Given noisy gates and a fixed number of lines, how can we use them to perform a computation as precisely as possible? In this paper we show approximate circuits can be deployed for computations with limited resources. Performing experiments on a QC simulator, we show that under the influence of noise, approximate circuits can have lower error-rates than exact circuits.
