Quantum computing creates the fog and the lighthouse

Quantum computing has the power to change that dynamic. The technology’s speed in certain applications sounds like science fiction. Google’s Willow quantum chip, for example, performed in less than five minutes a computation that would take today’s supercomputers 10 septillion years.

If bad actors enabled their deepfake engines with quantum computing suited for the task, the results could have 1,000 times better fidelity. It’s a scary thought. The face would be slightly asymmetric, the wrinkles would go in the correct direction, a few hairs would stick up and the background would perfectly match that of a department of motor vehicles.

The only way to detect that advanced type of synthetic ID would be to use quantum computing to develop machine learning that can spot the tiny signals in the noise of a fake document. In other words, we’d have to use a quantum computing defensive capability to match the quantum computing attack.
