Projects under coldqubit

One home, growing into an ecosystem.

Independent tools that share one standard: declarative workflows, container-first reproducibility, statistical rigor, and honest status reporting. Today there is one, and room for more.

alpha

CI/CD quality gates for quantum circuits. Statistically validate the probabilistic output of quantum programs across simulators and real QPUs, as declarative YAML, with drop-in exit-code gating. Validated on real hardware: ibm_fez, Bell/GHZ/Grover at 4096 shots.

planned

The gap between a runnable circuit and production is wider than one tool: scheduling, observability, policy, cost. If you want to build one of those layers in the open, there is a proposal form at the project home, and no working code is required to use it.

Project home & governance

One maintainer today, structured to grow.

coldqubit is an independent, open-source project home for quantum tooling, not a company and not a one-person hobby. It is built so that no decision depends on any one person staying available.

  • →Routine changes land by lazy consensus; substantial or hard-to-reverse changes are written down before they happen, org-scoped ones at the home, project-scoped ones as ADRs in the project.
  • →New projects start as a proposal issue at the home; every project commits to the same shared standards.
  • →Co-maintainers are welcome at every level, including for a single area such as a backend, the Terraform module, or the docs.

One recognizable system

You should always know where you are.

Every coldqubit surface, from CLI output to docs to this page, speaks the same language: terminal-native type, green/red PASS/FAIL semantics, one accent per project. Cyan means you are at the home; solar coral means shotgate.
