The Download: Microsoft’s quantum chip, and explaining rising energy demand

Feb 20, 2025 - technologyreview.com
The article provides an overview of recent technological developments and trends. Microsoft has made progress in creating topological quantum bits, which could lead to more stable and scalable quantum computers. This advancement, detailed in a Nature paper, represents a different approach from competitors like Google and IBM and could significantly impact the future of quantum computing. Additionally, electricity demand is projected to rise by 4% annually through 2027, driven by factors beyond just AI and data centers, according to the International Energy Agency.

The article also highlights efforts to create a biodegradable alternative to spandex by the company Good Fibes, addressing environmental concerns associated with petroleum-based fibers. Other stories include the financial struggles of electric truck maker Nikola, Google's new AI 'co-scientist' tool, and the challenges faced by America's first-generation chipmakers. The piece concludes with a look at Syracuse, New York, as a potential high-tech hub, spurred by the CHIPS and Science Act, which aims to revitalize US semiconductor manufacturing and neglected regions.

Key takeaways:

  • Microsoft has developed a chip containing eight topological quantum bits, which could lead to more stable and scalable quantum computers.
  • Electricity demand is expected to grow at close to 4% annually through 2027, driven by more than just AI and data centers.
  • A company named Good Fibes is working on creating biodegradable alternatives to spandex to address environmental concerns.
  • The CHIPS and Science Act aims to revitalize US semiconductor manufacturing, with Syracuse, New York, as a potential high-tech hub.
