Quantum Cryptography: Two Teams Use GPT-5.6

Two teams have solved the same quantum cryptography problem using GPT-5.6 in just three hours apart. According to Scientific American, MIT PhD student Seyoon Ragavan worked on one side, while professors Prabhanjan Ananth (UC Santa Barbara) and Amit Sahai (UCLA) worked on the other.

Both researchers used the same AI model but took different approaches to “non-clonable encryption,” a method that relies on quantum properties. They are now considering merging their work. However, this situation raises a broader question: when every researcher has access to the same models, what still constitutes an independent discovery?

“If someone mentions an open problem, the first thing to do is see if GPT solves it,” says Ananth. Ragavan puts it bluntly: “The way I do research now has nothing to do with how I did research two months ago.” Mathematics, in particular, feels the impact of AI, and reactions range from excitement over new possibilities to depression due to a lost sense of identity.
