What Happens When Quantum Computers Break Today’s Encryption — And How Developers Can Build Apps That Survive the Disruption.
What Are Quantum-Ready Apps?
Quantum-ready apps adopt: Post-quantum cryptography (PQC) algorithms (already standardised by NIST). Hybrid encryption models that work now and transition later. Modular security layers that can be upgraded when quantum threats become real.
How to Start Building Quantum-Resistant Software
- 1. Use NIST-Approved Post-Quantum Algorithms
- 2. Adopt a Hybrid Cryptographic Model Many organisations (Google, Cloudflare) are implementing hybrid encryption — combining classical and quantum-safe algorithms.
- 3. Audit for Long-Term Data Sensitivity Classify what parts of your app deal with long-life sensitive data (health records, legal files, financial info).
Final Thoughts:
If you’re building apps today that handle secure data, waiting until quantum threats are real will be too late.
Whether you’re a startup CTO, enterprise architect, or backend developer, now is the time to quantum-proof your app architecture.
