A primer on quantum security

451 Research is establishing a new cross-discipline Center of Excellence for Quantum Technologies.
In preparation, this report provides a beginner’s guide to quantum key exchange based on what Einstein called ‘spooky action at a distance.’

The 451 Take
Quantum key distribution guarantees the secure transmission of a key, but it is still susceptible to other attacks – if an unauthenticated malicious caller rings the holder of the key, for example, and persuades the holder to email it to them, the benefit of quantum technology goes out the window. As such, it is not a panacea, but another technology in the security toolbox to be considered on a case-by-case basis. Considering the complexity, immaturity and expense of quantum technologies, suitable cases will be few and far between. But for government and highly confidential communications, such an investment might be worth it, especially when quantum computing becomes more available.

SecureRF is listed as one of the firms that currently use quantum technologies in the secure communications arena.
