— Our Origin —
Started on WhatsApp. Became a movement
In early 2026, a single message went out to a small group of students curious about quantum computing. No funding. No institution. Just a question: what if we learned this together?
The response was immediate. Within days, hundreds of people had joined — students, researchers, developers, and professionals at every level of quantum familiarity. That first session ran on nothing but curiosity and a Google Meet link.
Now, 60 days later, we meet every Sunday at 4 PM without fail. Six cities. One community. The barrier to deep tech was never ability — it was access. We are fixing that.
— How it works —
Every Sunday is three acts
PART 01
UPDATES
Weekly Tech Digest
What happened in quantum computing this week. Papers, breakthroughs, industry moves — curated and discussed.
PART 02
LEARNING
Concept Deep Dive
One member teaches. Everyone learns. From Shor's algorithm to error correction — one concept explored deeply.
PART 03
SHOWCASE
Member Spotlight
Members present their projects, research, or ideas. Real work from the community, live every Sunday.
— Monthly Challenge —
Build real quantum tools. Together
Every month, we ship one open-source quantum tool as a community. One problem statement. One repository. Contributions at every level. A finished product by month end.
Quantum Circuit Simulator
qcsim
A state vector quantum circuit simulator with an interactive terminal UI, Python API, and a community-contributed circuit library. Built by the community, for the community.
Reference implementation ships with:
- State vector simulator — up to 20 qubits
- Interactive terminal circuit builder (arrow-key navigation)
- Python API with method chaining
- Kronecker + Tensor simulation backends
- 52 passing tests
- Community circuit library with SHA-256 deduplication
Contribution tiers — pick your level:
Beginner
- Submit circuits to the community library
- Test the CLI and file bug reports
- Explore the visual circuit builder — no coding needed
Intermediate
- Add new quantum gates (step-by-step guide included)
- Improve CLI commands and output formatting
- Write additional test cases
Advanced
- Build a Bloch sphere visualiser
- Implement noise models
- Connect to IBM Quantum or IonQ hardware
- GPU backend or density matrix simulation
Challenge drops on the 1st
A reference implementation — working skeleton, passing tests, contribution guide included.
Community builds it out
Fork, pick something to build, submit a PR or your own version. Every skill level has meaningful work.
