QuantumLeap: Quantum Computing

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.
