Q-Day: Every Lock in the World Is Made of Math - A Quantum Thriller

Every lock in the world is made of math. And the math just broke.At 13:58 UTC, someone factors a 4096-bit encryption key and posts it to the internet like a signature. No demand. No manifesto. Just proof.Within minutes, the world's most secure networks go transparent. Nuclear command protocols. Banking systems. Power grids for fourteen nations. Every secret ever whispered into a "secure" channel is suddenly readable - and the machine that broke the math isn't finished. By midnight, it will have read everything.There is exactly one defense: a network of dormant satellites that can rebuild the world's locks using the one law of physics that can't be hacked, cloned, or factored - quantum entanglement. Activating it means one physicist keeping a quantum processor alive at fifteen thousandths of a degree above absolute zero, two hundred meters under the Arctic permafrost. It means a cryptographer racing north with a four-minute window and no second attempt. And it means someone is already inside the mountain, waiting to make sure the lights never come back on.Q-Day is a race-against-the-clock techno-thriller for readers of Daemon, Ghost Fleet, and Michael Crichton at his most technically unnerving - where the clocks lie, the physics doesn't, and the only people standing between the world and total transparency are the ones who show up.Because somewhere behind the mathematics is a man who broke every lock on Earth for the most human reason there is - and his reason is the one secret the machine could never read.
