Improbable can say, with some confidence, that no-one has even seen a ‘Quantum Dragon’. But that shouldn’t be taken to mean that they don’t exist. Dr. Mark A. Novotny Professor and Head of the Department of Physics and Astronomy at the HPC² Center for Computational Sciences, Mississippi State University, US, asserts that they do – and he was the first to describe (and name) them in his paper ‘Energy-independent total quantum transmission of electrons through nanodevices with correlated disorder’ Phys. Rev. B 90, 165103 – Published 3 October 2014.
This illustration from the paper shows (an artist’s impression of) how a nine-part Quantum Dragon might look, if it could, in any normal sense of the word, be seen.
