Quantum Computing Mobile App

Use real quantum hardware on your mobile

Most quantum computing apps stop at a simulator on the phone, which is a fine way to learn and leaves the real machines out of reach. The ZKSF app goes the whole way. Write a circuit on your phone, choose a quantum processor, confirm the price, and the job runs on physical qubits in a real quantum computer, with the result waiting in your history when it finishes.

It was the world's first mobile app to talk to real quantum hardware, and as of 2 October 2026 it remains the only one.

Eight quantum processors from seven manufacturers

Every major way of building a qubit is on the list, superconducting circuits, trapped ions, neutral atoms and photons, so you can send the same idea to very different machines and compare what comes back.

Each one runs real shots on real hardware, and the app shows you the price and asks you to confirm before anything is charged.

24 engines on your phone, from GPUs to Google TPUs

Real hardware is half the story. The same app reaches the simulators that make quantum computing practical day to day.

• NVIDIA GPU clusters with 24 GB and 141 GB of memory, for exact simulation of large circuits, photonic programs, analog pulse sequences and neural quantum states
• Google Cloud TPU v5e and v6e, for exact circuits up to 29 qubits and neural network ground states. Our TPU vs GPU benchmark shows how they compare
• CPUs for exact statevectors, Clifford circuits with thousands of qubits, tensor networks, Pauli propagation, device noise previews and pulse level simulation
• An automatic router that reads your circuit and picks the cheapest engine that fits, for when you would rather not choose

What you can run from the quantum computing app

• Quantum circuits in OpenQASM, pasted, loaded from a .qasm or .txt file, built gate by gate, or started from a template such as a Bell state, Grover search or QAOA
• Batches of up to 200 circuits in one go
• Your own pulse sequences and linear optics programs, plus sweeps over their parameters
• Optimisation problems, the ground state of your own Hamiltonian, a sweep of ground states, a maximum independent set on neutral atom hardware and a quantum state reconstruction from measurement records
• Quantum error correction experiments that measure how often a logical qubit fails
• An estimate before every run, so you know the cost before you commit
• Your full history, searchable and sortable, with billed seconds, CSV export, results drawn as images and a banner when a hardware job finishes
• Certificates for results, so a number you share can be checked by anyone
• Billing with spend by tier and by day, and a calculator that shows what your balance buys

Learn quantum computing on your phone

The app is a learning tool as much as a lab. Everything you need to go from a first Bell state to a working algorithm is close at hand, and every idea links to something you can actually run.

• Step by step tutorials on quantum entanglement and the Bell state, Grover's search algorithm, QAOA for MaxCut, VQE for the H2 molecule, quantum teleportation and the Bernstein-Vazirani algorithm
• Explainers on quantum circuit simulation, tensor networks, logical and physical qubits, neutral atom quantum computing and post quantum cryptography
• A [quantum computing dictionary](/glossary-of-essential-quantum-computing-terms-for-beginners/) of the essential terms, written for beginners
• A guide to [quantum algorithms](/algorithms/), and a guide to every engine with what each one does best and where it stops

Reproduce real quantum computing applications

Reading about quantum computing is one thing. Rerunning a published result with your own hands is how it sticks. Our applications pages publish sixteen real world problems with the circuits, the shot counts and the bills attached, and the docs show how to rerun each one.

• Industry problems in space and satellites, logistics, manufacturing, finance, scheduling, traffic, chemistry and cryptography
• AI and quantum cases including quantum generative models, quantum reinforcement learning, quantum image generation and neural network quantum states

Simulator or real quantum computer?

Both, and the app shows you why. A simulator gives the ideal answer a perfect machine would return. A real quantum processor gives you what physics actually does, noise and all, and comparing the two is one of the fastest ways to understand where the field really stands. Run a Bell state on a simulator, then on a superconducting chip and a trapped ion machine, and the differences teach you more than any textbook chapter.

Get the quantum computing app

The ZKSF app is free to download from Google Play for Android. Create an account in the app, add credit when you are ready to run, and pay only for what you use. The same account works on the web console and with the Python SDK.

Quantum computing app questions

Is there a mobile app that runs on real quantum computers?

Yes. The ZKSF app for Android sends circuits to eight real quantum processors from Rigetti, IQM, IonQ, AQT, QuEra, Pasqal and Quandela. As of 2 October 2026 it is the only mobile app that does.

Can I run a quantum computer from my phone?

Yes. Write or pick a circuit, choose a quantum processor, confirm the price and submit. The job runs on the hardware and the result appears in your history.

Do I need to know quantum physics to use it?

No. Templates run with a single tap, and the tutorials, the dictionary and the application pages build up the ideas as you go.

What does it cost?

Pay as you go. Simulator jobs start from $0.0001, and every job shows its estimate before it runs. Real quantum hardware is priced by the provider's task fee and per shot rate, shown in the app before you confirm.

Everything here is runnable on your own circuit. Try it in the console
