Simulation of a quantum teleportation. The top qubit starts out in the "up" state, while the middle and bottom qubits are entangled in the Bell state. The circuit can be used to move the state of the top qubit onto the bottom qubit. Press the spacebar to start the qubits moving in the circuit. Can you work out how to turn the bottom qubits state into the top one? Try dropping gates onto the yellow dots. "Controlled gates" are only applied based on the outcome of the Bell measurement.
