A Free Introduction to Quantum Security
The quantum threat to cryptography is real. NIST has published the first post-quantum standards, and migration is already underway. If you want to understand what that means for your organization or your career, this free one-hour course is the place to start.
It is also a genuine sample of how Quantum Academy teaches: structured, evidence-based, vendor-independent, and built for working professionals. If you find this course useful, our full programs apply the same approach in much greater depth.
What This Course Covers
In about an hour, you will come away able to:
- Explain, in plain terms, why quantum computers threaten the cryptography that protects data today
- Understand the difference between the quantum computing milestones in the headlines and the specific capability that would actually break encryption
- Recognize the harvest-now-decrypt-later threat and why it makes the timeline shorter than it appears
- Identify what NIST has standardized and what a migration involves at a high level
- Know where to go next if you want to build real competence
Course Outline
Part 1. The Threat (about 20 minutes)
What quantum computers can and cannot do. Why public-key cryptography is vulnerable and symmetric cryptography is less so. The difference between quantum advantage and a cryptographically relevant quantum computer. Why no one can give you a firm date, and why that does not mean you can wait.
Part 2. Why Now (about 20 minutes)
The harvest-now-decrypt-later threat: data being collected today for future decryption. Trust-now-forge-later: the risk to digital signatures. The regulatory deadlines, insurance pressures, and client expectations that make migration urgent, whenever a quantum computer arrives.
Part 3. What Comes Next (about 20 minutes)
What NIST standardized and why it matters. What a post-quantum migration involves at a high level. How organizations are approaching it. Where to go from here if you want to develop real skills, lead a migration, or earn a credential.
Who This Is For
Anyone curious about quantum security: security professionals, IT staff, managers, people studying the field, and the simply curious. No technical or cryptography background is required.
Format
Free. Self-paced. Approximately one hour. Available on the Quantum Academy learning platform. Enroll with just an email address and start immediately.
What You Will Not Find Here
This short introduction does not prepare you for a Quantum Academy exam or to lead a migration. For that, take our Post-Quantum Foundation course and the PQCS certification track. This free hour gives you a working mental model and helps you decide where to invest next.
After This Course
If you want to go further:
- Post-Quantum Foundation: the half-day course that begins the certification track
- Quantum Security for Executives: if you make the decisions and others implement them
- Browse all courses and certifications, the full catalog across every quantum technology domain
Who this course is for
Anyone who has been asked what the quantum threat means for their organization and would rather not answer from headlines. Security staff, IT managers, risk and compliance people, and the executives briefing them. No technical background is assumed and none is needed.
If you already work on migration planning, this hour will be too shallow. Start at Post-Quantum Foundation instead.
What you’ll be able to do afterward
- Explain the quantum threat to current cryptography in plain language
- Distinguish harvest-now-decrypt-later exposure from signature exposure
- Describe what the NIST post-quantum standards do and do not settle
- Judge whether a vendor or press claim about quantum timelines is credible
What you leave with
You leave with the course handbook, a PDF of the full material with the instructor notes written out in place of the slides’ bullet points. Keep it and share it.
Where this course fits
No prior knowledge is needed. Start here. The paid next step is Post-Quantum Foundation, where the certification track begins. If you are more interested in the technology itself, Introduction to Quantum Computing is the other free introduction.
Why we teach this
The course is built on the Applied Quantum PQC Migration Framework. The practitioners who teach here wrote it, and it is published openly under Creative Commons at pqcframework.org. The people who teach this course run migration programs inside organizations today. The course covers the problems they meet in that work.
Certificate of Attendance
Upon completion, you receive a Quantum Academy certificate of attendance. It confirms that you attended the course and is separate from Quantum Academy’s professional certifications.
About this program
Quantum Academy credentials are private professional credentials issued by Quantum Academy, a trade name of Post-Quantum Institute. They are not government-issued licenses, accredited degrees, or academic credit, and earning one does not guarantee employment, promotion, regulatory approval, or any other specific outcome.
Quantum Academy programs are educational and informational only, and are not legal, compliance, or engineering advice.
