Quantum computing is rising as the future of cryptography and networking will continue taking shape

In 2024, we will see the adoption of post-quantum cryptography (PQC) – even before it is standardized – as a software-based approach that works with conventional systems to protect data from future quantum attacks. PQC will be used by browsers, operating systems, and libraries, and innovators will experiment at integrating it into protocols such as SSL/TLS 1.3, which governs classic cryptography. PQC will also start to trickle down to enterprises as they aim to ensure data security in the post-quantum world.

Another trend will be the growing importance of quantum networking, which in the not-so-distant future – 4 or 5 years (perhaps more) – will enable quantum computers to communicate and collaborate with each other for more scalable quantum solutions. Quantum networking will leverage quantum phenomena such as entanglement and superposition to transmit information. Last year, we correctly predicted that quantum key distribution (QKD) would roll out more widely with upgrades to data centers, autonomous cars, and consumer devices. QKD as an alternative or a complement to PQC depending on the level of security and performance required, will also leverage quantum networking. Quantum networking will be a growing area of research and investment for sectors such as government and financial services, which have high demands for data security and processing.

We are witnessing a quantum revolution, and we need to adapt. One of the key challenges of the future will be how to protect data, and one of the big opportunities will be how to harness quantum computers. We’ll be hearing a lot more about this in 2024.

In 2024, organizations will broadly adopt PQC as a software-based solution that works with existing systems – even before it is standardized. We will also see massively growing investment in quantum networking. The future is quantum, and nobody wants to be left behind.
