Weak Measurement: A Peephole into the Quantum World

Traditionally, measurement in quantum mechanics implies strong measurement. The latter, according to von Neumann, involves the collapse postulate. By contrast, weak measurements allow us to follow the detector- system interaction through Hamiltonian dynamics. I will review the advantages of weak measurement and a derivative protocol called weak value, and will discuss how they can be harnessed to obtain unusually strong amplification of weak signals, detection of many-body virtual states, and non- local excitations. Furthermore, I will discuss future challenges, of harnessing weak measurements to engineer and control on-demand quantum states
