Sourcing Quantum Random Numbers (QRN) from a quantum device for use by classical computers need not involve a quantum device at the user end. Quantum Technology Companies (QTC’s) transmit QRN over a secure channel (e.g., using Quantum Key Distribution (QKD) or an encrypted classical channel). So they remain protected during transmission. However, the risk is at the points where they are generated, stored, or used. SDS can be used to encrypt QRN at their source, transmit at PQR standard along classical channels and then decrypt just-in-time when used by a classical computer. This offers classical computers the opportunity to access QRN, that firstly cannot be compromised, and secondly, without the need of expensive hardware, nor the time and money for the integration of the hardware into existing classical architecture. This is an add-on service to existing Quantum Technology Companies (QTC’s) who supply QRN on demand. In other words, SDS will greatly improve the security at the end-points of QRN transmission without loss of security during transmission.
