Charlotte Gartenberg: 微软和谷歌近期在量子计算领域的突破性进展引发了人们对该技术的关注和投资热潮。 Asa Fitch: 量子计算机利用量子比特进行计算,它不同于传统计算机的比特,可以同时处于多种状态,从而实现更快的计算速度。除了微软和谷歌,IBM和其他一些公司也在探索量子计算技术,许多人认为这项技术具有巨大的潜力,特别是在药物研发等领域。量子计算能够更快地进行复杂的物理模拟和计算,从而加速新药的研发进程。例如,在谷歌去年的一项基准测试中,量子计算机在几分钟内解决了一个问题,而传统计算机则需要24个七百万亿亿年才能解决。微软声称研制出一种利用拓扑超导体的量子芯片,可以大幅提升量子比特数量,但这项技术仍存在争议,距离商业化应用还有很长的路要走。许多量子计算策略需要将系统冷却到接近绝对零度以减少噪音并提高稳定性。强大的量子计算机可能破解现有的加密技术,但人们正在积极开发抗量子加密技术。量子计算的商业化应用时间存在分歧,乐观估计为数年内,悲观估计为数十年后。 Charlotte Gartenberg: 对量子计算的未来发展和应用前景进行了总结和展望。

Deep Dive

Chapters
This chapter introduces quantum computing, explaining the difference between bits and qubits and how the latter's ability to be in multiple states simultaneously allows for faster calculations. It also mentions various companies involved in quantum computing research and development.
  • Quantum computers use qubits, unlike classical computers that use bits.
  • Qubits can be in multiple states at once, enabling faster calculations.
  • Companies like IBM, Google, Microsoft, IonQ, and D-Wave are exploring quantum computing.
