Quantum teleportation
Transfer an unknown quantum state using entanglement and two classical bits.
Back to learning pathQuantum information applicationsWhy this experiment matters
What you will do
Understand that teleportation moves state information—not matter—and still requires ordinary communication.
- 01
Share an entangled pair between Alice and Bob.
- 02
Alice jointly measures the unknown state and her qubit.
- 03
Bob uses two classical bits to choose a correction.
04 · PREDICT
Predict before you measure
Choose one answer to unlock the measurement.
INTERACTIVE
Interactive model
Move the control, then run a measurement. This is a teaching simulation—not hardware output.
Make a prediction, then run the measurement to reveal the expected and sampled results.
Measurement results
What the result shows
Fresh test states verify Bob's output with the selected fidelity. Alice's original state is gone, and no information travels faster than light.
