This extreme fragility might make quantum computing sound hopeless. But in 1995, the applied mathematician Peter Shor discovered a clever way to store quantum information. His encoding had two key properties. First, it could tolerate errors that only affected individual qubits. Second, it came with a procedure for correcting errors as they occurred, preventing them … Read more
This is a job for LLL: Give it (or its brethren) a basis of a multidimensional lattice, and it’ll spit out a better one. This process is known as lattice basis reduction. What does this all have to do with cryptography? It turns out that the task of breaking a cryptographic system can, in some … Read more
Joanna Stern of The Wall Street Journal. Courtesy of Joanna Stern If Vision Pro is mostly meant to be used from a couch cushion or desk chair, the external battery pack may not factor in as much. As I pointed out last spring, it’s an unusual choice for a consumer tech company that has, over … Read more
The cost of making further progress in artificial intelligence is becoming as startling as a hallucination by ChatGPT. Demand for the graphics chips known as GPUs needed for large-scale AI training has driven prices of the crucial components through the roof. OpenAI has said that training the algorithm that now powers ChatGPT cost the firm … Read more
Andersen and Lensky of Google disagree. They do not think the experiment demonstrates a topological qubit, because the object cannot reliably manipulate information to achieve practical quantum computing. “It is repeatedly stated explicitly in the manuscript that error correction must be included to achieve topological protection and that this would need to be done in … Read more
