1. A method for securing communications between an initiating device and a participating device using quantum random numbers, the method comprising:
establishing, by quantum random number (QRN) management circuitry of the initiating device, a first secure communication channel between the initiating device and a remote quantum random number (QRN) source;
obtaining, by the QRN management circuitry of the initiating device, a quantum random number (QRN) from the remote QRN source using the first secure communication channel between the initiating device and the remote QRN source, the QRN being a true random number; and
using, by security circuitry of the initiating device, the QRN to participate in computer implemented services with the participating device that received the QRN from the remote QRN source over a second secure communication channel established between the remote QRN source and the participating device wherein information based on the QRN is also received by an authentication service.
