Abstract

Employing an optical microcavity interacting with a nitrogen-vacancy (NV) center with excellent optical performance and scalability, two logic-qubit controlled-not (CNOT) gates in decoherence-free subspaces (DFSs) are successfully constructed against collective-rotating noise and collective-dephasing noise, respectively. The circuit has a heralded function that can filter out incorrect components. Furthermore, a waveform corrector (WFC) is adopted to balance the amplitude of two components in different spatial modes, thereby achieving high fidelity.

氮空位中心辅助下无退相干子空间中的逻辑量子比特CNOT门。

利用光学微腔与具有优异光学性能和可扩展性的氮空位（NV）中心相互作用，成功地在无退相干子空间（dfs）中分别构建了两个逻辑量子比特控制非（CNOT）门，以抵抗集体旋转噪声和集体退相噪声。该电路具有预先通知功能，可以滤除不正确的元件。此外，采用波形校正器（WFC）来平衡两个分量在不同空间模式下的振幅，从而实现高保真度。

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
