Development infrastructure

Write a job. See what it will take. Then send it.

QCOS meets you in Python, in a terminal or through an assistant. The first run is on a CPU simulator, so you can learn the whole flow before you think about a machine.

Read the docs See QCOS

Four ways in, one set of jobs.

Python SDK

Submit, wait, read the counts and fetch the evidence from a program of your own.

pip install softqcos-sdk

softqcos CLI

The same jobs from a terminal or a script, down to offline verification of the evidence.

softqcos doctor

MCP server

The official QCOS server for assistants and agents that speak the Model Context Protocol.

softqcos-mcp

REST API

The contract underneath the three of them, for anything else that speaks HTTP.

/api/v1/runtime

From Python.

Python SDK

from softqcos_sdk import QCOSClient

qcos = QCOSClient(api_key="your-api-key")

# See what the job will take, without running it
estimate = qcos.jobs.estimate(
    qasm=bell_state,
    backend_id="simulator",
    shots=1000,
)

job = qcos.jobs.submit(
    qasm=bell_state,
    backend_id="simulator",
    shots=1000,
)
result = qcos.jobs.wait(job["job_id"])
print(result["result"]["counts"])

# Every run records an evidence bundle
print(qcos.jobs.artifacts(job["job_id"]))

From a terminal.

softqcos CLI

$ softqcos doctor
$ softqcos jobs submit \
    --circuit circuits/bell-state.qasm \
    --backend simulator \
    --shots 1000
$ softqcos jobs status <job-id>
$ softqcos jobs results <job-id>
$ softqcos jobs evidence <job-id> \
    --output evidence.json
$ softqcos evidence verify evidence.json --offline

Guides to real problems.

What we are building next

Less quantum to learn before you can start.

HiQVision

Your own functions, on a quantum computer

Call ordinary C and Python functions from a quantum program, and see what they will cost in qubits first. HiQ is a design today; there is no compiler to download yet.

QCOSVision

An editor that answers back

Write, estimate and run from the editor you already use, without leaving your file.

Softquantus CloudVision

A rehearsal before the real run

Try a job against a software stand-in for the machine you chose, before you spend anything on it.

Deployment infrastructure

Put a job inside your own software, with access and cost under control.

Execution infrastructure

Follow a job from your code to a sealed result.
