Abstract:
Weak measurement is an alternative to von Neumann’s dogma of the “collapse” of a wave function: it avoids the necessity of the latter’s complete destruction, while capable of extracting partial information from the system measured. Concomitantly, measurement is associated with a back-action of the detector on the system’s state. This back-action can be harnessed for the purpose of steering a quantum state into a pre-designated target state, hence for quantum engineering of non-trivial states of matter. Likewise, one may employ this unavoidable backaction to extract energy from the system.  I will try to package it all: steering, quantum cooling, and the relation to driving protocols of open systems and to active error correction platforms.
