Cryptography and Java Java provides cryptographic functionality using two APIs: JCA - Java Cryptography Architecture - security framework integrated with the core Java API JCE - Java Cryptography Extension - Extensions for strong encryption (exported after 2000 US export policy)

For example, quantum cryptography is a direct application of quantum uncertainty and both quantum teleportation and quantum computation are direct applications of quantum entanglement, the con-cept underlying quantum nonlocality (Schro dinger, 1935). I will discuss a number of fundamental concepts in quantum physics with direct reference to .

1. Quantum bits In quantum computing, a qubit or quantum bit is the basic unit of quantum information—the quantum version of the classical binary bit physically realized with a two-state device. A qubit is a two-state (or two-level) quantum-mechanical system, one of the simplest quantum systems displaying the peculiarity of quantum mechanics.
