QuantumLeap: Quantum Computing

Learn quantum computing with lessons, exact circuits, and daily challenges.

Quantum computing can feel abstract. QuantumLeap makes core ideas touchable through eight concise lessons, exact circuit challenges, and an interactive two-qubit state-vector simulator.

LEARN AT YOUR PACE

• Work from classical bits and qubits through measurement, superposition, gates, entanglement, interference, and noise.
• Check your understanding with three applied questions in every lesson.
• Continue where you left off with progress stored only on your device.

BUILD QUANTUM CIRCUITS

• Apply Hadamard, Pauli-X, Pauli-Z, and CNOT gates.
• Inspect all four basis-state probabilities and complex amplitudes.
• Try verified guided circuits for Bell pairs, interference, SWAP, Grover search, and superdense coding.
• See how phase changes interference without changing immediate measurement probabilities.

SOLVE CIRCUIT CHALLENGES

• Recreate exact one- and two-qubit target states with limited gates.
• Follow a curated 12-puzzle practice path with a distinct physical target on every board.
• Solve one offline daily challenge from a 23-target no-repeat cycle and build a local streak.
• Get credit for physically equivalent states that differ only by global phase.

PRIVATE BY CONSTRUCTION

• Works offline.
• No account.
• No ads or analytics.
• No personal-data collection or sharing.
• Reset lesson and challenge progress at any time.

QuantumLeap models ideal one- and two-qubit systems. It does not connect to physical hardware and is intended for general education, not as a substitute for a formal course or professional advice.
