Quantum key distribution logon widget

This invention describes a system that uses quantum physics to secure a login screen. It works by exchanging special quantum keys in both directions between a computer and a device. If an eavesdropper tries to listen in on this key exchange, the system detects it by comparing the quantum data, and then decides if it's safe to show the login screen or takes other security actions.

Why it matters: Quantum Key Distribution (QKD) hardware has seen significant miniaturization and integration since 2017, making device-level implementation more plausible. However, the cost and infrastructure requirements for widespread deployment remain substantial.
