India, May 14 -- The Government of India has issued a release:
Scientists have uncovered a surprising quantum phenomenon which shows that sometimes, two particles prepared in opposite states can reveal more information than two identical ones.
The findings can improve the characterization of unknown quantum devices and benefit quantum cryptography protocols.
In quantum physics, not everything can be known at once. This fundamental limitation, known as Bohr's complementarity principle, tells that certain properties of a quantum system cannot be simultaneously determined with perfect precision. Famous examples include the trade-off between path information and interference visibility in the double-slit experiment, as well as impossibility ...
