No account, no key

Run a quantum program.
Get an answer you can check.

Write OpenQASM, or start from an example. The service picks the strongest way to simulate your circuit, tells you which and why, says how exact the answer is, and signs it.

Program

Ask for
Measurement counts. 0 for none.
Pauli strings, comma-separated. Qubits count from 0.
Bit strings, qubit n−1 first.
Noise

Each a probability, after every gate on the qubits it touched; readout on each measured bit.

Method

In this browser, the same engine plans and runs the job, offline, signed with a key made for this browser; a tab holds less than the service, and the plan says when a job needs more. For an editor that checks the program as you type, with an assistant, open Quantum Studio.

Result

ready

Run a program to see its result here.

Counts are keyed by the program's classical bits, highest bit first. With no measurement, every qubit is read into the bit of its own index.

From an agent

Any client that speaks the Model Context Protocol can use the service as tools: add one URL, with no key. The tools run a circuit, read a job, verify a receipt, describe the service, and list worked examples. Each answer comes as a short summary written for a model to read, with the whole result alongside. 

{
  "mcpServers": {
    "wai-quantum": {
      "type": "http",
      "url": "https://wai.transaction.science/quantum-jobs/mcp"
    }
  }
}

For other programs: the OpenAPI description, the examples as JSON, and a summary for language models at /llms.txt.

What it can run

auto tries these in turn and takes the first that fits the circuit and what you asked for. The limits are the service's own, read live.

MethodTakesUp toAccuracy

To build circuits by hand and watch them evolve, use the quantum IDE, which runs in the tab. To learn the ideas, take the course.
