McKinsey’s latest quantum communication report explores growing investment in new quantum communication capabilities to help meet expanding demand for enhanced cybersecurity and quantum computing.
Momentum is intensifying behind quantum communication, a technology segment with significant potential to affect cybersecurity and quantum computing. By addressing the widespread vulnerabilities of existing security standards to quantum computing–based decryption, quantum communication enhances the security of communication networks. Quantum communication technologies also play a critical role in the infrastructure needed to deploy high-impact, fault-tolerant quantum computers at scale.
Quantum communication applications include quantum key distribution for secure communications (may be combined with post-quantum cryptography), local quantum networks (including modular interconnects for quantum computers), and global networks (such as a quantum internet for distributed quantum computing).
