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
Apple has rolled out an update to iMessage encryption, the likes of which includes post-quantum protections that the company calls the “most significant cryptographic security upgrade” in the messenger’s history. The M3 MacBook Pro: Made Dark for Halloween In a blog post published Wednesday, Apple announced the arrival of PQ3, a new encryption protocol designed to … Read more
Apple is launching its first post-quantum protections, one of the biggest deployments of the future-resistant encryption technology to date. Billions of medical records, financial transactions, and messages we send to each other are protected by encryption. It’s fundamental to keeping modern life and the global economy running relatively smoothly. However, the decades-long race to create … 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
Hotta discovered, to his shock, {that a} easy sequence of occasions might, the truth is, induce the quantum vacuum to go unfavorable—giving up vitality it didn’t seem to have. “First I assumed I used to be incorrect,” he stated, “so I calculated once more, and I checked my logic. However I couldn’t discover any flaw.” … Read more
