Abstract
We review recent developments in the foundation and application of the quantum theory of entangled systems. Subjects include

• Schrödinger's Cat Paradox,
• Einstein-Podolsky-Rosen (EPR) Paradox,
• Bell's Inequalities,
• Greenberger-Horne-Zeilinger (GHZ) entangled states,
• Quantum Cryptography, -Communication, -Computation, and Quantum Games.

Outline:

1. Information and communication theory
2. The qubit
3. Two qubits:
   • no cloning theorem
   • EPR states
   • Bell inequalities
   • GHZ states

Quantum Information Processing:

• Q cryptography
• dense coding
• Q teleportation
• the Deutsch decision problem
• Shor's algorithm for efficient factorizing of large numbers
• Physical implementations, limitations
