TheQuantCloud is the unified platform for quantum development — from writing your first qubit to running circuits on cloud simulators and real quantum hardware. Sign up for free beta access with $50 in credits.
From your first quantum hello-world to production-grade circuit deployment, TheQuantCloud provides the complete development lifecycle.
Write circuits once with our clean Python API. Export to Qiskit, Cirq, or OpenQASM when you need to. No vendor lock-in, ever.
High-performance tensor-based simulator for rapid prototyping. No network round-trips, no queue wait times.
Seamlessly switch from simulator to IBM Quantum, IonQ, and Rigetti hardware with a single parameter change.
Complete gate library — Pauli, Hadamard, Phase, T, CNOT, Toffoli, parameterized rotations, and custom unitaries.
Bidirectional conversion between QuantSDK, Qiskit circuits, and OpenQASM strings. Bring your existing code.
Structured measurement results with counts, probabilities, statevector access, and built-in visualization helpers.
PEP 561 compliant with strict mypy checking. Your IDE autocomplete works perfectly — catch errors before runtime.
A full-featured development environment for quantum computing. Write, run, visualize, and share quantum circuits — no local setup required.
VS Code's editor engine with QuantSDK autocomplete, Python syntax highlighting, and intelligent error messages. Write quantum code with the same editor millions of developers already love.
SVG circuit diagrams, interactive result histograms, probability bars, and statistical analysis — all updated in real-time.
Bell states, Grover's search, QFT, VQE, QAOA, teleportation, quantum ML, and more. One-click load into the editor.
Compare and select from CPU, GPU, IBM, IonQ, Rigetti, and Quantinuum backends with real-time status and metrics.
Save your circuits, manage projects, and pick up right where you left off. Full CRUD with auth-protected storage.
Download results as JSON, CSV, or SVG. Export circuit diagrams for papers and presentations.
Email + GitHub OAuth via Supabase Auth. Your circuits are private by default, with cloud sync and API key access.
Clean, Pythonic, and intuitive — QuantSDK gets out of your way so you can focus on the physics.
