Building India's quantum chip.

We design superconducting quantum processors in India — and publish exactly what we measure.

Why we exist

Design and build India's quantum chip — and publish exactly what we measure.

Processors designed around the error correction they run. We measured what connectivity costs an error-correcting code — that measurement is the design brief for our first device.

What we've measured →

Every result with its caveats, dates, and job IDs. The ledger, in public.
How we're building it →

Measure first. Design for the code. Build in India.
Who we are →

Four founders, design-stage, bootstrapped. No more, no less.

1 Encoded-pair measurements, post-selected, 2026 · 2 circuit-level simulation, Stim + minimum-weight matching · 3 public dataset of Google Quantum AI (Zenodo, CC-BY-4.0) — their measurement, our decoder · every condition, acceptance rate and job ID: the ledger.

The device

Designed around the code it runs.

The measurements above choose the geometry: a degree-4 lattice, so the correcting code routes without detours.

How we operate

Pre-registered, raw shots archived, every number re-derived offline — by a small team, at commodity cost.

Our first chip is in design.
