Quantum testing can compare unknown photon states in a manner suitable for a validation check of a quantum digital signature, testing of the operation of a quantum gate, or detecting of entanglement. The system comprises: a server configured to collect user identity document data from the user and to construct a token including the user identity document data encoded in a machine readable form; a key construction unit communicatively coupled to a reader configured to read the data from the token and configured to read the data encoded on the storage device. The first device may have a flexural rigidity between 10\u22121 Nm and 10\u22126 Nm, and the ratio of the critical strain energy release rate to the material density factor for the first device may be greater than 0. If the authorization data matches the media player’s unique identifier, authorization is granted and the media player commences to read the media.
