The development of quantum networking technology will ultimately yield more secure and higher-speed connectivity, but it’s still very early in the game and many challenges remain before it becomes mainstream.
While core quantum networking technologies such as repeaters and photonics are being developed, it is security applications – specifically post-quantum cryptography (PQC) – that are likely to be the first real-world developments that come out of the lab, according to Liz Centoni, executive vice president, chief strategy officer and general manager of applications at Cisco. PQC, or quantum-safe cryptography, features complicated cryptographic algorithms that are expected to protect quantum computers from sophisticated attacks.
