Abstract

NOT gate is one of the basic units in quantum computing. While it suffers from the noise during the complex operation. In this paper, we simulate the NOT gate on the superconducting phase qubit and solve the noise problem by maximizing the impact of noise cancellation. We first extract the noise term from the Hamiltonian and reset it to zero. Then we give two kinds of pulses based on the non-noise term for the quantum gate. By using these pulses, the fidelity would be improved and benefit quantum computing.

超冷凝相位比特上的高保真非门

NOT 门是量子计算的基本单元之一。但它在复杂的操作过程中会受到噪声的影响。在本文中，我们模拟了超导相位量子位上的 NOT 门，并通过最大限度地消除噪声影响来解决噪声问题。我们首先从哈密顿中提取噪声项并将其重置为零。然后，我们根据量子门的非噪声项给出两种脉冲。通过使用这些脉冲，保真度将得到改善，并有利于量子计算。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
