Mikhalychev as part of Quantum Optics and Related Topics\n\n\nAbstract\nSpecific properties of quantum measurements (backact ion on the measured object\, randomness of the outcomes) lead to “hidden ” character of quantum information and hinder investigation of quantum s ystems. On the other hand\, inevitable influence of the measuring device o n the quantum system can serve as an instrument for steering it to a usefu l target state. The talk is devoted to that aspect of quantum measurements : special measurement types capable of creating various target states\; ge neral ideas of measurement-induced control of quantum states\; interpretat ion of dissipative (non-unitary) dynamics of quantum systems in terms of c ontinuous measurements and its usage for generation of non-classical quant um-optical states. Namely\, a class of “elimination” measurements is d efined\, discussed\, and shown to be efficient for quantum light state man ipulation. Further\, the idea is extended to the field of quantum imaging and an approach to conditional enhancement of photonic state sensitivity t o the illuminated object sub-Rayleigh features is proposed. The close conn ection between dissipative non-unitary dynamics and measurement-induced st eering of a quantum state makes the concept of “elimination” measureme nts also fruitful for description of an optical system subjected to nonlin ear coherent loss and showing its capability of generating sub-Poissonian quantum-optical states.\n LOCATION:https://researchseminars.org/talk/QOART/9/ END:VEVENT END:VCALENDAR
