Guided projects

PREREQUISITE

Quantum Coin Flip

Prepare a one-qubit 50/50 state. Compare 10, 100, and 10,000 shots. Explain why the counts are not always exactly equal. Save your circuit.

Complete Measurement and shots →
PREREQUISITE

Bell State Explorer

Prepare Φ+. Change it into Φ−, then Ψ+. Compare amplitudes, probabilities, and reduced Bloch vectors. Save a separate experiment for each state.

Complete Entanglement →
PREREQUISITE

Quantum Random Number Generator

Use three independent H gates to prepare a uniform superposition over eight bit strings. Sample the state, interpret bit strings as integers 0–7, and check the frequencies. Simulator randomness is not certified hardware randomness.
