As reported in Physical Review Letters, Dr Paul Skrzypczyk and Professor Noah Linden looked at the way in which we gain information about the world at the quantum scale through the process of measurement. This work has been selected as an Editor’s Suggestion “due to its particular importance, innovation, and broad appeal.”
They found that the ability for a measurement to be highly informative is intimately related to how robust the measurement is to imperfections or noise.
They also uncovered a connection to a branch of quantum information science which concerns communication. Viewing the measurement as a special type of communication channel, they found that its ability to communicate well is related in the same way to how robust the measurement is… READ MORE
