Quantum Threat to Encryption and AI's Role in Cybersecurity Discussed by Industry Leaders

• •Quantum computers may break current encryption by 2030, necessitating immediate action.
• •Enterprises are lagging in adopting post-quantum cryptography, risking future vulnerabilities.
• •AI's evolution is expected to reshape cybersecurity practices and enterprise software significantly.

IBM CEO Arvind Krishna and Palo Alto Networks CEO Nikesh Arora discussed the imminent threat posed by quantum computing to current encryption methods during a podcast on October 22, 2026. Krishna predicts that quantum computers capable of breaking public-key cryptography will emerge around 2030, urging organizations to adopt post-quantum cryptography immediately. Both leaders emphasized the need for enterprises to transition to quantum-safe infrastructure, as existing systems are vulnerable to future quantum attacks. They also debated the impact of AI on cybersecurity, suggesting that open-weight models may dominate over frontier AI models, reshaping enterprise software and security practices. The conversation highlighted that many organizations are already late in their migration efforts, with Krishna noting that a significant portion of the IT estate cannot be replaced quickly. Arora echoed this sentiment, stressing the urgency for businesses to act now to secure their systems against the upcoming quantum threat.
