A global, vendor-neutral space for practitioners preparing for the quantum decade.
The Quantum Security Community exists to bring clarity, evidence-based insight, and practical collaboration to one of the most important technology shifts of our time.
This forum is our long-form knowledge hub — a place for thoughtful discussions on PQC migration, crypto-agility, Q-Day readiness, CRQC modeling, quantum-safe architectures, quantum sensing risks, and the security of emerging quantum technologies.
Whether you’re here from FS, telecom, government, research, cybersecurity, cryptography, or quantum engineering, we’re glad you’re here.
Getting Started
1. Introduce yourself
Add a short introduction in #introductions on Slack (or create a post here if you prefer).
Tell us what you work on, what brought you here, and one topic you’re especially interested in.
2. Explore the discussions
Browse the categories to get a sense of ongoing conversations.
When you find a post that’s interesting, informative, or valuable, click the 
— it helps highlight high-signal content.
3. Join the conversation
Ask questions, share insights, respond to open threads, or start a new topic.
Before posting, please take a moment to review our Community Guidelines.
4. Be generous with what you know
Many members are just beginning their PQC or quantum-readiness journey.
Your experience — even early lessons learned — helps the entire community.
Community Ecosystem
The Quantum Security Community spans several platforms, each with a different purpose.
Here’s where everything lives:
Main Hub - https://quantum.security
Your starting point for everything: events, links, resources, community channels, and updates.
Slack - https://slack.quantum.security
Real-time discussion on PQC migration, crypto-agility, Q-Day modelling, CRQC timelines, OT/CNI, standards, research, and more.
LinkedIn Group - https://linkedin.quantum.security
Professional space for broader industry discussions, announcements, and community news.
Community Events - https://events.quantum.security
Online meetups, local chapter gatherings (London, Dubai, Singapore, etc.), and full-day Quantum Security Community Forums.
Weekly Digest - https://newsletter.quantum.security
A curated summary of the most important discussions, research, standards updates, and community insights across all channels.
Useful Tips
• Use categories wisely
Each topic belongs somewhere — and each category has a clear purpose. If unsure, post in General and we’ll help move it.
• Tag light, not heavy
Tags are optional and meant for cross-cutting themes (e.g., modalities, regions, specific standards).
• Disagree respectfully
Quantum security attracts strong opinions — and that’s good.
But keep discussions technical, evidence-based, and professional.
• Share resources
Tools, templates, research links, slides, conference notes — all welcome.

We want this space to be as useful, welcoming, and high-signal as possible.
Final Note
Thank you for being part of this community.
Quantum security is a complex, multidisciplinary problem — but none of us need to navigate it alone.
Let’s build a clear, connected, and quantum-safe future together.
