1. A method for secure cryptographic secret distribution, comprising:
receiving, at a trusted key relay station quantum device for a trusted key relay station, a cryptographic secret from a webserver quantum device for a webserver over a first communication network
storing, by the trusted key relay station, the cryptographic secret;
authenticating, by the trusted key relay station, an end user via an end user electronic device;
generating, by the trusted key relay station, a machine-readable code comprising the cryptographic secret; and
displaying, by the trusted key relay station, the cryptographic secret on a display on the trusted key relay station;
wherein the end user electronic device is configured to capture an image of the machine-readable code on the display of the trusted key relay station, to extract the cryptographic secret from the machine-readable code, to store the cryptographic secret in secure storage on the end user electronic device, to encrypt data with the cryptographic secret, and to communicate the encrypted data to the webserver over a second communication network.
