Didn't even read it, responding to the headline alone. No they can't. Will edit after reading more about why they can't. Which I stand by, as the blockchain is my witness, they just can't. EDIT: I shouldn't have bothered checking, yes a Petahertz is a million times a Gigahertz, but that's the only thing they've got to ride on. So the size of the chip at that point comes into play, and it would have to be 3D, so then will it have a dimension left for the laser. Well I think a Terahertz would be possible, for sure. But later, like in the fifties. After researching other questions and finding answers to this question in a roundabout way.
