Protective Measurement—A New Quantum Measurement Paradigm: Detailed Description of the First Realization
2021
Applied Sciences
We present a detailed description of the experiment realizing for the first time a protective measurement, a novel measurement protocol which combines weak interactions with a "protection mechanism" preserving the measured state coherence during the whole measurement process. Furthermore, protective measurement allows finding the expectation value of an observable, i.e., an inherently statistical quantity, by measuring a single particle, without the need for any statistics. This peculiar
