Quantum Chinese Magic Box [article]

Radel Ben-Av
2017 arXiv   pre-print
Once the measurement is performed, the information in this basis is retrieved. At the same time, due to wave function collapse the information in the other basis is lost and cannot be retrieved.  ...  This property is achieved by storing the information using a set of non-orthogonal quantum states. The different drawers are realized by different orthogonal set of basis for the measurement.  ...  Is there any advantage in using qudits as a basis for CMB? How does the CMB function when there is a quantum noise?  ...
