Sample interview questions: Explain your familiarity with experimental techniques for testing quantum teleportation.
Sample answer:
Experimental Techniques for Testing Quantum Teleportation:
- Bell Inequality Test: Determine if quantum states are correlated in a non-local manner, a violation of Bell’s inequality would support teleportation.
- Quantum State Tomography: Reconstruct the full quantum state of the teleported qubit to verify its fidelity with the original state.
- Entanglement Characterization: Confirm the entanglement between the qubits before and after teleportation using entanglement witnesses or Bell state measurements.
- State Transfer Fidelity: Measure the fidelity of the teleportation process by comparing the reconstructed state with the original state using a process tomography protocol.
- Teleportation Distance Extension: Test the limits of teleportation by increasing the distance between the sender and receiver while maintaining… Read full answer
