Kim Mackrael: 我报道了欧盟对苹果和Meta的巨额罚款,以及它们对国际贸易的影响。欧盟的《数字市场法案》旨在为小型科技公司创造更公平的竞争环境,而对苹果和Meta的罚款则源于他们违反了该法案中关于数据使用和开发者沟通的规定。苹果和Meta都表示将对罚款决定提出上诉,并认为这些决定对用户隐私和安全以及产品有害。欧盟的这一举动正值美欧贸易谈判紧张之际,可能会对这些谈判产生影响。虽然罚款金额占公司总收入的比例很小,但罚款以及要求改变商业运营方式的命令,可能会引起其他在欧洲运营的科技公司的关注。 欧盟对Meta的罚款与其强制用户同意将数据与其他产品结合以提供个性化广告有关。欧盟对苹果的罚款与其限制应用程序开发者引导用户使用其他购买方式有关。 Aylin Woodward: 我报道了量子通信领域的突破性进展。研究人员使用普通计算机和现有的光纤电缆网络,在德国三个城市之间成功传输了量子信息,打破了该技术的距离纪录。这项研究使用了无需昂贵制冷技术的室温设备,降低了成本并提高了实用性。量子通信对于保障信息安全至关重要,它可以保护健康记录和财务记录等敏感信息免受网络窃听。量子互联网的最终目标是通过量子通信技术来提高信息安全,虽然普通用户可能不会直接连接到量子互联网,但它将间接提高数据安全水平。 量子信息与经典信息不同,它使用量子比特而不是比特,量子比特可以同时存储多个值,从而提高安全性。量子通信比传统通信更安全,因为它使用基于量子力学的加密密钥,这些密钥几乎无法破解。

Shownotes Transcript

Scientists have made a huge leap in a highly technical practice known as coherent quantum communications). The WSJ’s Aylin Woodward breaks down what that is and the effects it could have on everyday life. Plus, our Brussels-based reporter Kim Mackrael takes us through the trade implications of the European Union’s fines) on Apple and Meta Platforms. Katie Deighton hosts.
