Securable network in 3 party network
... This study proposed two three-party QKDPs to demonstrate the advantages of combining classical cryptography with quantum cryptography. Compared with classical three-party key distribution protocols, the proposed QKDPs easily resist replay and passive attacks. Compared with other QKDPs, the proposed ...

Quantum Cheshire Cat
... Now that we understand what weak measurement is, we need to implement it into the photon experiment in order to prove that quantum Cheshire Cat really exists. We replace detector D1 with a CCD camera that measures displacement of the beam from the central position [2]. We can realize measurement of ...

A maximality result for orthogonal quantum groups
... uij are the coordinate functions which take a matrix to its (i, j)-entry. In fact every commutative unitary Hopf algebra is of the form R(G) for some compact group G ⊂ Un . In general we use the suggestive notation “A = R(G)” for any unitary (resp. orthogonal) Hopf algebra, where G is a unitary (res ...

Moreover, they have more entropy than any form of ordinary matter in the same volume. This suggests the holographic pri ...
