The theoretical eventuality known as Q-Day may arrive much sooner than previously thought.
I’m just the blogger who works nights and weekends for Gizmodo. If I could get into the nitty-gritty of cryptography and quantum computing, I would be off doing that. With that said, this concerns a somewhat ominous security-related update from Google that happens to involve cryptography and quantum computing.
It’s the theoretical future day when a quantum computer will have the capability to essentially break all cryptographic security, potentially creating a sort of hacking and identity theft armageddon.Moving the deadline for the switch to PQC to 2029—around the time of the next U.S. presidential inauguration—is a pretty dramatic escalation. It sounds like the previously accepted timeline was not a tangible date in the future, but a sort of hand wave, like the “day” in the future when there’s abundant energy from nuclear fusion. Pure speculation, or is it?showing, as Goodin put it “that a 2048-bit RSA integer could be factored in less than a week with a quantum computer with 1 million ‘noisy qubits.’”. They may have actual “qubits,” and those qubits may actually enter “superpositions” and undergo “entanglement” . But they are too error-prone to be any sort of revolution in computing, or threat. The qubits are tooSo to quote Goodin again, “In 2012, most estimates were that a 2048-bit RSA key could be broken by a quantum computer with a billion physical qubits.” One million noisy qubits is apparently a much more doable prospect than a billion precise ones, thus Google’s sense of alarm. Does this mean you need to get in your apocalypse bunker, or ask your smartest cousin to set up some kind of PQC action plan for all your gadgets? Doubtful. It sounds like this is mainly something in the realm of cybersecurity that cryptographers need to stay on top of. But it also sounds like are remarkable change in our expectations for quantum computing. Capabilities once thought further out—unfortunately the7:30 amI’m a Computing Dummy Who Tried Quantum Coding. Here’s What Happened My first attempt at quantum coding wasn’t nearly as painful as I’d feared—and it’s probably something you could do, too.Trump Reportedly Pausing $40 Billion AI and Quantum Deal With UK
