Building your first Qollab project·Lesson 5 of 5

Bring your own code into Qollab

Move a circuit you wrote locally into Qollab: the Qiskit carries over, and the pre-created backend replaces your provider setup.

A circuit you built with Qiskit locally runs in a Qollab project with one change: the pre-created backend replaces your provider setup.

Your circuit carries over

The Qiskit you write is standard, so the part that builds your circuit works unchanged: QuantumCircuit, gates, measurements, transpilation. Open + New Project, choose Upload your own files under Project shape, then drop individual files, a folder or an archive onto the card. You can also choose Files… or Folder…. Qollab builds the project from the uploaded contents. For a short, single-file example, paste the code into main.py in the Code tab.

Swap the provider setup for the pre-created backend

Locally, you create a provider with an API key and get a backend from it:

# Local: you manage the provider and key yourself
from qiskit_ionq import IonQProvider

provider = IonQProvider(token="your_api_key")
backend = provider.get_backend("simulator")

On Qollab, delete the provider lines because a backend is already created for you. Choose where it runs in the Select QPU dialog when you press Run:

# Qollab: backend is pre-created; just run against it
job = backend.run(circuit, shots=100)
print(job.result().get_counts())

Run and share

Press Run, pick a simulator (free) or real hardware (credits), and read your results in the console. Once you publish the project, others can open and fork it.
