Quantum State Interferography by Urbasi Sinha

Explore quantum state interferography in this colloquium talk by Urbasi Sinha from the Raman Research Institute. Learn about a novel interferometric method for characterizing qubit states using single-shot measurements, offering advantages over traditional quantum state tomography. Discover how this "black box" approach allows for true single-shot estimation of quantum states without changing setup conditions. Examine the extension of this technique to higher-dimensional qudit systems, providing significant scaling advantages. Delve into topics such as weak values, interferometers, and applications in quantum computing and communications. Gain insights into the potential for miniaturization and free-space quantum key distribution using this innovative approach to quantum state estimation.
