# Entanglement in Continuous Variable Systems

Martin Plenio (Imperial College)

## Abstract

In this talk I will outline the basic questions that are being studied in any theory of entanglement. Following a brief review of some of the main achievements of entanglement theory for finite dimensional systems such as qubits, I will then
consider entanglement in infinite dimensional systems. Asking for
a theory of entanglement in such systems under experimentally
feasible operations leads to the development of the theory of
entanglement of Gaussian states. Results of this theory are
presented and the tools that have been developed for it are then
applied to a number of interesting problems.
