As a result of the quantum confinement, the energy states of the trapped particles are discrete, which ma ...

... The number of Schmidt coefficients of a pure bipartite entangled states cannot be increased by any LOCC. Measure of Entanglement:1. For pure bipartite state entanglement is measured by the Von Neumann entropy of any of it’s subsystems. This is the unique measure for all pure bipartite states. 2. For ...

Approximate Quantum Error-Correcting Codes and Secret Sharing
... is already an error-correcting code, since it allows one to correct up to n − d erasures. Error-correcting codes need not be secret sharing schemes: a repetition code, for example, provides no secrecy at all. In the quantum world, the connection is much tighter. Cleve et al. [6] observed that any (p ...
