Description

We present quantum reading [3] realisation, describing theoretically and experimentally, as that quantum advantage is obtained by practical photon-counting measurements combined with a simple maximum-likelihood decision [4], demonstrating that quantum entanglement and simple optics are able to enhance the readout of digital data.
Then we consider [5] a protocol on conformance test. We formulate the problem in the context of quantum hypothesis demonstrating that quantum resources, namely twin beams [1,2], and a simple receive are able to outperform any classical strategy in recognizing whether or not a certain quantum channel conforms to a reference one.
