South Korean researchers claim to have achieved a room-temperature superconductor using a modified lead-apatite structure called LK-99. The superconductor exhibits a critical temperature above 400 K and offers potential for energy efficiency and advancements in technology. However, further verification, replication, and understanding of the material’s properties are necessary before widespread acceptance. The discovery could also have implications for quantum computing. Assessing scalability, cost, and environmental impact is crucial for real-world applications.

How quantum computing could transform everything everywhere, but not all at once
What does quantum computing have in common with the Oscar-winning movie “Everything Everywhere All at Once”? One is a mind-blowing work of fiction, while the other is an emerging frontier in computer science — but both of them deal with rearrangements of particles in superposition that don’t match our usual view of reality. Fortunately, theoretical physicistContinue reading “How quantum computing could transform everything everywhere, but not all at once”
Five Worlds of AI (a joint post with Boaz Barak)
Artificial intelligence has made incredible progress in the last decade, but in one crucial aspect, it still lags behind the theoretical computer science of the 1990s: namely, there is no essay describing five potential worlds that we could live in and giving each one of them whimsical names. In other words, no one has done forContinue reading “Five Worlds of AI (a joint post with Boaz Barak)”
