QCV Technology

The technology currently being prototyped by QCV will resolve the existing issues of single photon production.

An essential part of any cryptographic protocol is the key – a string of random bits that are used to encode the data to be exchanged between parties. The key is communicated by transmitting the information (light) via a fiber optic cable. This is open to security loopholes because keys can be easily compromised by the use of fiber tappers and sniffer software to gather fragments of data as it passes through the fiber. In effect, an eavesdropper wishing to steal information can take some of the transmitted light particles, while allowing the rest to pass through. In so doing, neither communicating party is aware eavesdropping has occurred. With a complete stream of encrypted data, powerful computers can attempt to crack the code.
