Welcome to the very first issue of the Quantum Security Community Digest - the weekly briefing for anyone working on PQC migration, crypto-agility, Q-Day readiness, CRQC timelines, quantum-secure architectures, and the evolving standards shaping the quantum decade.

This newsletter exists for a simple reason: quantum security has become too broad, too fast-moving, and too multidisciplinary for any one person or organization to keep up alone. The conversations that matter are increasingly happening across scattered channels - in Slack, LinkedIn, research papers, standards committees, technical blogs, hardware announcements, and global policy updates. The idea behind this digest is to bring the best of those discussions together in one place.

The home for everything we’re building lives at

https://quantum.security

- the central hub connecting all our community spaces, events, and resources. From there you can find links to join Slack, the LinkedIn Group, Discourse, meetups, the podcast, and more.

The Digest will surface and summarize the most important conversations happening across all these channels each week. Whether it’s a debate on crypto-agility patterns in Slack, a CRQC forecasting thread on LinkedIn, a new PQC migration article on PostQuantum.com, an insightful talk at a local meetup, or an upcoming standards update - this newsletter aims to bring clarity, context, and signal.

Where this community lives

This community is intentionally multi-layered, because quantum security itself spans multiple disciplines, technologies, and audiences.

(Many of the communities are being set up now. Please go to Quantum.Security to access latest, correct links)

Core Community Hubs

These are the spaces where the community interacts, debates, asks questions, and shares progress:

• Slack - Quantum Security Community Slack

  Our real-time hub for technical discussion, research sharing, Q&A, and collaboration across PQC, CRQC, QKD, sensing security, and emerging standards.

• LinkedIn Group - Quantum Security Community

  A professional space for researchers, engineers, CISOs, and policymakers. Great for analysis, discussion prompts, and broader community visibility.

• Discourse - Quantum Security Community

  Our long-form, structured space for deep technical threads, research breakdowns, standards analysis, and durable community knowledge.

Content & Insight Channels

These channels anchor the editorial and knowledge-sharing side of the community:

• PostQuantum.com - Evidence-based analysis of quantum computing progress, PQC adoption, crypto-agility, and CRQC capability.

• Newsletter (this Digest) - Weekly curation of discussions, research, standards, and events.

• Podcast - Quantum Security Podcast (launching soon)

  Expert conversations, briefings, and deep dives into PQC transitions, CRQC progress, QKD realities, and the future of cybersecurity.

• YouTube - Quantum Security Community

  Interviews, explainers, event recordings, and video briefings.

• TikTok - @quantum_security

  Short, accessible clips breaking down PQC, CRQC, and quantum-security concepts without hype.

• Twitter/X & BlueSky

  Fast updates, insights, research highlights, timelines, and community news.

🎓 Learning & Skills Development

As the community grows, we’re building out a learning ecosystem:

• Quantum Security Learning Hub

  Online courses, explainers, workshops, and training programs on PQC readiness, CRQC fundamentals, hybrid trust, and quantum-safe architectures.

🌍 Events & Connection

• Meetup - Quantum Security Community Global Chapters

  Online sessions and local in-person meetups for talks, workshops, and hands-on quantum-security discussion.

• Eventbrite - Quantum Security Annual Conference

  Our flagship event gathering researchers, practitioners, and leaders across the ecosystem.

💼 Careers & Opportunities

• QuantumCareers.com

  A growing job board connecting PQC, quantum-security, hardware, cryptography, and research professionals with global opportunities.

What to expect from this Digest

Each issue will bring together:

• The most insightful community discussions from any channel

• Key developments in PQC migration & crypto-agility

• Updates on CRQC capability & Q-Day forecasting

• New research, papers, and technical breakthroughs

• Standards and policy movement (NIST, ENISA, ETSI, ISO, NCSC, CISA, BIS, MAS, etc.)

• Practical guidance and implementation lessons

• Highlights from events, meetups, and the podcast

• Tools, resources, and community announcements

In other words:

a curated, high-signal snapshot of what matters in quantum security each week, or more often depending on the events in the industry.

Thank you for being here

This community is built for practitioners, researchers, engineers, architects, policymakers, and leaders preparing for the quantum era - whether you’re deep in PQC migration, modelling CRQC capabilities, designing quantum-safe systems, or tracking quantum sensing risks.

The Quantum Security Community is global, neutral, research-driven, and collaborative.

And this Digest is your window into it.

Thank you for joining early - more coming soon.
