SynapseX by SoftQuantus

A scientific ecosystem for research, experiments and simulation.

Simulators, modelling tools and a quantum lab for research and experiments. QCOS, our hybrid, hardware-agnostic scientific engine, runs circuits on simulators today, checks whether quantum is a sensible candidate, and seals a record of every run. Partner QPU access, GPU and HPC compute are in development. Nothing paid runs without your approval.

Assistants give you answers. Clouds give you machines. SynapseX is the research workspace between them — modelling software, simulators and the QCOS engine, ending in one sealed record of what ran.

Six ways into the ecosystem.
Every run ends in sealed evidence.

How an experiment runs

From question to sealed evidence
in one experiment loop.

Coding agents won by owning a loop — reproduce, isolate, fix, confirm. SynapseX Labs runs the same loop on science, where the instruments are simulators today, and partner QPUs, GPU and HPC compute are in development.

QCOS — the engine

One engine
under every tool.

QCOS is SoftQuantus's hybrid, hardware-agnostic scientific engine for quantum circuit workloads, offered as an SDK, a CLI, an API and an MCP server you run yourself. Today CPU simulators are live (exact to 24 qubits); partner QPU gateways, GPU and HPC compute are in development. QCOS checks whether quantum is a sensible candidate before you spend, and seals what ran under a SHA-256 Merkle root.

Evidence

Reproducibility isn't a feature.
It's the output format.

Each execution produces a sealed evidence record: what ran, where, with which seed and parameters, at what cost, returning which distribution. Recompute the hash, re-run the probe, or attach the record to a paper or an audit. The seal shows the record was not altered; it does not say who produced it.

If a result can't carry its evidence, SynapseX doesn't call it a result.

Why we build our own models

A model is only as useful
as the experiment loop around it.

SynapseX models are products inside the ecosystem, next to the meter, the engine and the evidence. The sealed record carries the run's backend, seed, parameters, raw results and cost. Recording a whole session as one trajectory — problem → diagnosis → probe sequence → cost → sealed outcome — is in development.

General models read papers about experiments. We are training ours to plan them — which cheap probe to run first, what it costs, and when to stop. The aim is that failed probes stay in the record instead of disappearing.

Pricing

Simulation is free within the Free limits: up to 100 simulation runs a month, one at a time, up to 60 seconds each, on CPU only. Beyond them, or on paid hardware, you pay in credits — estimated first, reserved before it spends, settled for what it used.

FAQ

Frequently asked questions
about the SynapseX ecosystem.

SynapseX is a scientific ecosystem for research, experiments and simulation: simulators, modelling tools, a quantum lab, and QCOS, our hybrid, hardware-agnostic scientific engine, offered as an SDK, CLI, API and an MCP server you run yourself. Chat, agents and our models are products inside it, not the whole of it. Simulators and sealed evidence are live today; partner QPU access, GPU and HPC compute are in development.

No. Describe the problem in your domain's language. QCOS checks whether quantum is a sensible candidate before you spend anything, and often the honest answer is to use classical methods. That result is a suitability check, not a speed-up claim.

The Free plan has no time limit. It includes quantum simulators with sealed evidence: up to 100 simulation runs a month, one at a time, up to 60 seconds each, on CPU only. That's the product, not a trial. Past those limits, or on paid compute, you pay in credits.

Estimate → your approval → atomic reservation → execution → settlement for actual usage. Over-reservation is released, never silently kept. The append-only ledger is queryable via API.

A record of the run — backend, seed, parameters, raw results, cost — sealed under a SHA-256 Merkle root. Recomputing the root detects any alteration, down to a single byte, so the record is tamper-evident and lets anyone with access check it was not changed. The seal shows integrity, not who produced the record.

Yes. QCOS is offered as an SDK (softqcos-sdk), a CLI (softqcos), a REST API and an MCP server (softqcos-mcp) that you run yourself. Any MCP-capable agent can list backends, estimate, submit jobs and fetch evidence. Our models are one way into the lab, not the only one.

Today QCOS runs on CPU simulators: exact state-vector simulation up to 24 qubits. Partner QPU gateways, GPU simulation and managed HPC execution are in development. The catalog only lists what is live.

Tenant isolation end to end — your jobs, evidence and ledger are scoped to your organization. We do not train our models on your private research without an explicit, revocable opt-in; the full data-use policy is published before general availability.

Running jobs finish on their reservation. New paid jobs return an honest HTTP 402 with a top-up link. Nothing ever runs unfunded.

Bring a research question.
Leave with sealed evidence.

Simulator probes cost 0 credits and every run ends in a sealed record. Start in SynapseX Labs, or call QCOS from the SDK, CLI, API or MCP.
