Qolab
Qolab, Inc. is a superconducting quantum computing hardware company founded in 2022, with offices in Los Angeles, California and research laboratories in Madison, Wisconsin. Co-founded by 2025 Nobel laureate in physics John Martinis and Alan Ho — both of whom led hardware and product for Google's 2019 quantum supremacy milestone — Qolab builds high-coherence superconducting qubits by applying advanced semiconductor manufacturing processes to qubit fabrication, targeting the yield and integration problems that stand between quantum research and utility-scale machines. Its first deployable offering is Qolab Start, a turn-key superconducting QPU platform for pulse-level and device-level hardware research, sold to university labs, national laboratories and semiconductor R&D teams and delivered either on-premise or through secure cloud connectivity. Qolab has raised roughly $70M across a $16M Series A and a $54.2M Series B led by UC Investments, with strategic investment from Applied Ventures and Western Digital, and leads hardware development for DARPA's Quantum Benchmarking Initiative. Qolab publishes no public developer program: there is no developer portal, no machine-readable API contract and no self-serve sign-up, and the API and control interface guides that ship with Qolab Start are released to customers after a Request Access review.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Qolab the way a machine reads it — 4 machine-readable artifacts, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Qolab scores 12.4/100 (emerging), with a separate agent-readiness read of 3/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Why this profile is thin
Qolab's only product page names "API and control interface guides" as a deliverable of the Qolab Start QPU platform, but the sole route to them is the "Request access" form on that same page — there is no developer portal, no reference, and no api./docs./developer. subdomain (all three NXDOMAIN), so the contract is behind a sales conversation rather than published.
An API exists — we simply could not reach the contract without credentials or a sales conversation. This one is Qolab's to change: publishing the reference and a machine-readable spec at a public URL, while keeping key issuance behind whatever gate they like, would let an integrator evaluate the API before committing to a call.

Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Qolab
Each block below is one kind of artifact we hold for Qolab. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Pricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
Published pricing tiers and plan structures.

PLANSRate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

This is an independent, third-party profile of Qolab, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
