A
Error-corrected by construction
Every logical qubit is woven from 49 physical ones in a distance-7 surface code. Faults are caught and undone every 1.1 microseconds, so a circuit a million gates deep still lands on the right answer.
01 — The machine
A machine you can booknot a roadmap
B
Called like a function
Install the SDK, decorate a circuit, await the result. Standard circuit formats run unmodified.
# pip install singularity-sdk @horizon.job(qubits=212) def ground_state(h): ... energy = await ground_state(femoco)
C
Priced per logical-second
No reservations, no minimums. You pay $0.84 for each second your circuit holds a logical qubit, and nothing at all while it waits in the queue.
02 — Workloads
