Episode 05 – Decrypting the Future: How Quantum Computing Will Reshape Cybersecurity

In this high-stakes episode of Quantum Logic, host Spencer Scott explores how quantum computing could become both the greatest threat—and the greatest ally—to digital security.

While classical computers struggle with today’s encryption challenges, quantum machines may soon crack them with ease. But that same power could also revolutionise cybersecurity—boosting threat detection, enabling quantum key distribution, and reshaping how we defend against tomorrow’s breaches.

Spencer breaks down how quantum computing is forcing a global rethink of encryption—from looming algorithmic threats to the urgent rollout of post-quantum standards and next-gen security innovations.

This episode asks:

• When will quantum computers be strong enough to break encryption?

• Is “quantum-safe” security actually achievable?

• What should CISOs and IT leaders be doing right now?

Perfect for professionals in cybersecurity, tech leadership, and quantum research—or anyone curious about the future of digital trust.
