Quantum Computing Visualizer

Quantum Computing Visualizer replaces confusing equations with interactive 3D visualizations, real‑time animations, and hands‑on simulations. You don’t just read about qubits – you watch them spin, collapse

Why this app is different

Most quantum computing courses start with abstract linear algebra and complex numbers. Students give up before they ever see a qubit.

Quantum Computing Visualizer turns that upside down. Every concept is paired with a live simulation:

Qubit → see it as a glowing sphere

Superposition → slide the probability dial and watch the state change

Measurement → click and watch the wavefunction collapse

Entanglement → link two qubits and see instant correlation

You build intuition first. The math comes later – only when you want it.

What you can explore

🔬 Quantum Lab

A full single‑qubit simulator. Rotate the Bloch sphere in real time. Apply X, Y, Z, H, S, T gates. Watch probabilities update as bars. Measure and see the collapse animation.

🌌 Superposition Visualizer

Two sliders control amplitude and phase. See exactly how |ψ⟩ = α|0⟩ + β|1⟩ changes. No hidden complexity – just drag and observe.

🔗 Entanglement Simulator

Two qubits, CNOT gate, and four probability bars. Create Bell states (|00⟩+|11⟩)/√2. Change one qubit – the other responds instantly. Understand Einstein’s “spooky action” by doing.

🎛️ Circuit Builder

Build quantum circuits by stacking gates on a wire. Run the simulation and see the final state vector and probabilities. Perfect for testing small algorithms.

📊 Measurement Lab

Measure a superposition 1, 10, or 100 times. Watch the histogram grow closer to the true probabilities. Learn why quantum measurement is inherently probabilistic.

📘 Concept Library

40+ topics from absolute basics to advanced research:

Qubits, Bloch sphere, measurement

All important gates (Pauli, Hadamard, phase, T)

Entanglement, teleportation, superdense coding

Algorithms: Deutsch, Grover, Shor, QFT

Error correction, surface codes, NISQ, quantum supremacy

Each concept includes a visual explanation and a “Try it yourself” link to the relevant simulator.

Perfect for
