(Phys.org)—It was an interesting week for physics as a combined team of researchers from China and Singapore demonstrated new violations of local realism—they have shown that all mixed entangled states that conform to ...
(Phys.org)—Demonstrating that limits were made to be broken, physicists have overcome what was previously considered to be a natural and universal limit on the efficiency of a quantum cryptography task called blind quantum ...
Accurately probing the delicate relationship between linked, or 'entangled', photons—irrespective of the distance between them—is an important element of quantum cryptography, and perhaps even teleportation. Now, A*STAR ...
