Quantum Communication & Security

Protection of data is a global concern. CQT has expertise in both quantum key distribution (QKD) and post-quantum cryptography – two future-ready approaches to secure communication. We are working on a few approaches to sending quantum keys via fibre and satellite, to offer encryption resistant to all computational hacks. We also explore how to make mathematical cryptography schemes safe against future quantum computers.
