Photonics for Quantum 2 - Shared screen with speaker view

Thank you Professor Englund! I have 2 questions: 1. For the PICs, in terms of fabrication imperfections (MZI splitting ratios, phases etc.), how close are the designed unitary matrix to the actual unitary? How do we determine the actual unitary? 2. In a PIC network, the optical paths going through different number of optical components can suffer from different internal loss. Will this affect the shape of the output amplitude/probability distribution, especially in the quantum information cases? If so, how do we understand the actual output distribution and compare it with theoretical predictions?
Thanks. Very good talk. For the 2*2 MZI unitary matrix on Si, how critical to have exact 50% splitting ratio at splitter.
Great Talk, Dirk.Thanks!
