"Entanglement: A philosophical curiosity becoming a resource in quantum 
communication and  quantum computation"

Abstract:
Quantum entanglement, called by Albert Einstein "spooky action at a distance", 
was the essential characteristic of quantum mechanics to Erwin Schrödinger. 
Its conceptual significance is that a local realistic viewpoint is untenable 
as confirmed by numerous experiments today. Most interestingly, quantum 
entanglement has recently become an essential resource in various quantum 
information protocols. These include quantum cryptography and quantum 
teleportation. In the talk, I will review the experimental status and 
possible future applications including world-wide satellite-based quantum 
communication. Most recent results show that novel kinds of entanglement play 
a crucial role in the novel concept of one-way quantum computation, which 
might even provide new insights into the nature of computation itself.
