As quantum computing edges closer to practical reality, current cryptographic standards face unprecedented risk. This talk delivers a focused, technical overview of quantum algorithms threatening today’s encryption, like Shor’s algorithm and their real-world implications. Attendees will learn how to assess existing vulnerabilities, understand timelines for quantum risk, and implement actionable strategies to future-proof their security infrastructure. Through a hands-on demonstration using quantum simulators, we’ll bridge theory and practice, empowering defenders to anticipate and mitigate the post-quantum threat before it turns from theoretical to catastrophic.
