Thanks! Few clarifications: If you clone a chip, then first you have to buy each chip you wish to clone (so why bother counterfeiting?) Your maybe do not want

Thanks! Few clarifications: If you clone a chip, then first you have to buy each chip you wish to clone (so why bother counterfeiting?) Your maybe do not want to sell a lot of chips but only one chip to one specific buyer and also add some additional payload. I think it's not about relying on the uncertainty principle: if it were, then the output of the PUF would not be deterministic, which is not what you want! What I meant was that do they claim that their method works because you could not measure the quantum object without changing its state or they just say that it is just too complicated.
