WEAK MEASUREMENT: A Peephole into the Quantum World

The field of quantum measurement has become an exploding field of research in the past few years. Quantum measurements, particularly quantum weak measurements, are used to investigate exciting phenomena across different areas of physics. In my talk, I will discuss how weak measurements can be used to understand the phenomenon of quantum jumps which is one of the fundamental questions that have existed since the birth of quantum mechanics. More specifically, I will discuss how a quantum system evolves as it takes a quantum jump and whether these quantum jumps can be caught and reversed mid-flight. I will also mention the other highlights of quantum measurements, such as quantum state engineering and the measurement-induced geometric phase, where quantum weak measurement plays a significant role.
