Modern Physics and the Energy Conservation Objection
... Observers inside the train will calculate its kinetic energy as zero. On the other hand, since for observers stationed on the ground the train and ball will be moving with some velocity v, they will measure its kinetic energy as 1/2mv2, where m is the mass of the ball. Thus, the energy of the ball ...

Approximate Quantum Error-Correcting Codes and Secret Sharing

Secret Sharing and Quantum Error Correction Classically, an (n, d)-secret sharing scheme splits a secret into n pieces so that no d−1 shares reveal any information about the secret, but any d shares allow one to reconstruct it. Such a scheme is already an error-correcting code, since it allows one ...
