Quantum Lab - Learn & Build

Quantum Lab turns quantum mechanics and quantum computing into something you can see, touch, and experiment with - not just read about. Drag a qubit around a 3D Bloch sphere. Build a real quantum circuit gate by gate. Watch interference build up one particle at a time in the double-slit experiment. Run Grover's search algorithm and see the correct answer get amplified before your eyes.

No account. No ads. No internet connection required. Everything runs as a real quantum simulation on your device, built on an original state-vector engine - not pre-recorded animations.

WHO IT'S FOR
Whether you're a curious beginner, a STEM student learning linear algebra and probability, an engineering or computer science student studying circuits and algorithms, or simply someone who wants to understand what quantum computers actually do, Quantum Lab meets you where you are. Every lesson can be viewed at three levels of depth - Concept, Engineering, or full Math notation - switchable anytime.

LEARN BY DOING
- Structured lessons on quantum foundations, qubits, superposition, gates, and entanglement
- Interactive Bloch sphere with live state, probability, and matrix readouts
- Predict-then-run experiments that build real intuition

CIRCUIT LAB
- Tap-based quantum circuit builder - no fiddly drag-and-drop required
- Full single- and multi-qubit gate set: X, Y, Z, H, S, T, rotations, CNOT, CZ, SWAP, and more
- State vector viewer, probability histograms, and reduced Bloch spheres for multi-qubit states
- Measurement Lab with Z/X/Y bases and shot statistics from 1 to 10,000
- Noise Lab comparing ideal vs. noisy results
- Circuit Challenges that check your solution by physics, not by exact gate sequence
- Free-form Sandbox with preset circuits (Bell pair, GHZ state, and more)

PHYSICS EXPERIMENTS
- Double-Slit Experiment with a which-path detector toggle
- Phase Lab, Interference Lab, Entanglement Lab
- Bell Test correlation simulator
- Heisenberg Uncertainty Lab

QUANTUM ALGORITHMS
- Quantum Randomness, Bell States, Teleportation, Superdense Coding
- Deutsch-Jozsa, Grover's Search (with stage-by-stage amplitude visualization)
- Quantum Fourier Transform, Shor's Algorithm overview
- VQE and QAOA optimization demos

APPLICATIONS & HARDWARE
- Honest, jargon-free overviews of where quantum computing may help - chemistry, optimization, cybersecurity, materials science, finance, and more - including real limitations and classical alternatives
- Quantum Computer Explorer: the full stack from application down to physical qubits
- Compare real qubit technologies: superconducting, trapped ion, neutral atom, photonic, and spin qubits

Quantum Lab is built to avoid the common misconceptions that make quantum computing confusing - no "a qubit is 0 and 1 at the same time," no faster-than-light communication, no claims that quantum computers will replace classical ones or speed up every algorithm. Just clear, accurate, hands-on physics.

Quantum Lab is an educational simulation environment. Some experiments, hardware models, and applications are simplified to emphasize fundamental concepts and should not be interpreted as exact reproductions of laboratory hardware or proof of practical quantum advantage.
