Quantum computing capabilities are accelerating, pushing traditional encryption methods closer to obsolescence. In response, cryptographers and security professionals are advancing post-quantum cryptography (PQC) solutions designed to resist attacks from quantum-capable adversaries.

A range of candidate algorithms and transition strategies are under active evaluation for their cryptographic strength, implementation efficiency, scalability and applicability across real-world use cases. Below, members of Forbes Technology Council explore the PQC approaches they believe hold the most promise—including their advantages and trade-offs—to help organizations prepare for a quantum-resilient future.
