Using mirrors, beam-splitters, and blockers in a black-box to manipulate the light beam’s direction through this specific experiment, students are instructed to vary input and observe the output of light to get an idea of the possible inner structure. A black-box is a kind of experimental task where the inner structure is not visible to the experimenter. They have been evaluated in a lower-secondary school at the end of optics lessons. In this paper a sequence of nine, easy to manufacture optical black-box experiments with increasing levels of difficulty, and supportive frameworks for physics classes are introduced. Nine optical black-box experiments for lower-secondary students In the case of a black box performing a unitary transformation, randomly distributed according to the invariant measure, we give a complete solution of the problem, deriving the optimal tradeoff curve and presenting an explicit construction of the optimal quantum network. We address the problem of the information-disturbance tradeoff associated to the estimation of a quantum transformation and show how the extraction of information about a black box causes a perturbation of the corresponding input-output evolution. Information-disturbance tradeoff in estimating a unitary transformationīisio, Alessandro D'Ariano, Giacomo Mauro Perinotti, Paolo Chiribella, Giulio Finally, we show that black hole thermodynamics can be constructed in an ordinary way, by constructing statistical mechanics. In this way, the paradoxes of information loss and firewall can be resolved effectively. Then, by including those (quantum) metric perturbations, we show that the black hole formation and evaporation can be described effectively in a unitary manner, through a quantum channel between the exterior and interior of the event horizon. To confirm this statement, we show that the original black hole's ‘first law’ may not simply be treated as the first law of thermodynamics formally, due to some missing metric perturbations caused by matter. First, we show that the Bekenstein–Hawking entropy S BH may not be a Boltzmann or thermal entropy. In this paper, we try to construct black hole thermodynamics based on the fact that the formation and evaporation of a black hole can be described by quantum unitary evolutions.
