Popis:	Making measurements on single quantum systems is considered difficult, almost impossible if the state is a-priori unknown. Protective measurements suggest a possibility to measure single quantum systems and gain some new information in the process. Protective measurement is described, both in the original and generalized form. The degree to which the system and the apparatus remain entangled in a protective measurement, is assessed. A possible experimental test of protective measurements is discussed. Based on a talk delivered in the "Discussion Meeting on Quantum Measurements" at IISc, Bangalore (22-24 October 2014)
