Every time there is a story about physicists solving security, and especially cryptographic problems, I wonder how well they actually know these fields. Usually there is a statement of problem that simply isn't correct. In this case there is this: ´´´ In today's payment ecosystem, customers' sensitive data is substituted by sequences of random numbers, and the uniqueness of each transaction is secured by a classical cryptographic method or code. However, adversaries and merchants with powerful computational resources can crack these codes and recover the customers' private data, and for example, make payments in their name. ´´´ Ignoring the strange statement that "sensitive data is substituted by sequences of random numbers", the second part is second statement about powerful computational resources is simply wrong. And the suggested solution to the problem is also quite typical - it relies on equipment that basically require a lab to use. And it does not work with the infrastructure used today for payments. It doesn't scale, it would require replacing a lot of equipment and indeed the Internet itself.
