"When this quantum computer is realized that breaks current cryptography, current crypto will essentially be rendered obsolete. So everything that we rely on today - for communications, for data security - it's going to become exposed and vulnerable. And of course, that day it's realized, it's almost like flipping a switch. One day you're safe against traditional computer attacks, and then the next, the quantum threat is realized."
"According to research from Microsoft, this future could arrive sooner rather than later. The development of Majorana 1 could lead to quantum computing within years rather than decades. With reports suggesting that quantum computing could impact authentication security, data encryption, certificate and key management and more, failing to build resiliency for a post-quantum world could leave organizations vulnerable."
Quantum computing poses a near-term threat to current cryptographic protections and could render existing encryption and authentication systems obsolete. Many organizations remain unprepared: a quarter of digital trust professionals expect quantum computing within five years, yet 95% of organizations lack a quantum roadmap and only 5% prioritize preparation. Research indicates developments like Majorana 1 could accelerate arrival from decades to years. Potential impacts include compromised authentication security, data encryption, certificate and key management. Building quantum-resilience through migration planning, algorithm updates, and inventorying cryptographic assets is critical to prevent sudden vulnerability when quantum capabilities arrive.
