Roadmap

Direction, not dates.

Stages behind us carry the date they happened. Stages ahead carry the gate that unlocks them — the thing that has to be true before the next one can start. We do not publish a quarter for a qubit count.

  1. 2026 · done

    Measure the hardware that exists.

    Encoded-qubit and memory experiments on rented IBM Heron-class processors, as paying customers: a three-basis logical Bell fidelity with a confidence interval, 31 certified detection-code pairs, a repetition-code ladder, and the connectivity-tax negative. Pre-registered, raw shots archived, every caveat published on the ledger.

  2. Now

    Design the chip those measurements ask for.

    A four-qubit superconducting design — schematics, simulation, layout — with every design target traceable to a measurement we published. The status report says what closed and what did not.

    Gate the design package, reported in public — including the parts that did not close.

  3. Next

    Put it on silicon.

    Tape-out and fabrication of the first device. Bootstrapped work ends at the foundry door; this stage is a funding and partnership question as much as an engineering one.

    Gate foundry engagement, fridge access, and the capital to pay for both.

  4. After that

    Measure our own qubits.

    First cooldown, first coherence numbers from a device we made — published with their raw data whatever they are. Until this stage we quote design targets, never measurements, for our own hardware.

    Gate a fabricated die, in a fridge, with a working bring-up and calibration loop.

  5. Then

    Four to eight to sixteen.

    Each generation gated on what the previous one measured, not on a calendar. Error correction — as opposed to the detection we run today — needs distances and qubit counts that only arrive at the end of this ladder.

    Gate each generation’s measurements, published, before the next is committed.

When a stage completes it gets a date here and a write-up in the journal; if a stage is abandoned, that gets written up too.
