Sample interview questions: Discuss any experience you have with experimental techniques for quantum state tomography.
Sample answer:
Experimental Techniques for Quantum State Tomography
- Photon counting: Measuring the photon counts in different detectors to reconstruct the quantum state of the emitted photons.
- Homodyne detection: Measuring the amplitude and phase of coherent states that interact with the quantum system of interest.
- Maximum likelihood reconstruction: Estimating the quantum state by minimizing the difference between the measured and predicted probabilities.
- Linear optics and interferometry: Using optical elements to manipulate and measure the quantum state, such as in quantum entanglement swapping.
- Single-qubit and two-qubit state tomography: Reconstructing the state of individual q… Read full answer
