             QUANTUM  ENTANGLEMENT AND ITS RAMIFICATIONS

                             A. K. Rajagopal
             Naval Research Laboratory, Washington, D.C.

After a quick review of ideas of classical bits (cbit) leading to "modern"
conveniences such as telephone, TV, Computer technology etc, a discussion of
quantum bits (qubits) is given. This discussion includes a review of quantum
mechanics - superposition principle and uncertainty relations - whose
implications for qubits are explored. Consideration of two qubits in detail
will be shown to lead to new features, most importantly, entanglement. Several
applications of this (encryption, no copying, teleportation, computing) are
briefly discussed. Considerations of continuous variables where light sources
play the role of qubits will be touched upon.
