Quantum Information Processing with Continuous and Discrete Variables: Give it a Squeeze!
Prof. Dr. Peter van Loock (Johannes Gutenberg-Universität)

Squeezed states of light were proposed some decades ago with applications mainly in gravitational wave detection or general optical metrology.
Besides their fundamental significance as nonclassical states of light, more recently, squeezed states were found to be a useful resource in quantum information processing. While this type of application was initially based solely upon an encoding in terms of continuous phase-space variables, optical squeezing is now also beginning to emerge as a useful resource in the more conventional discrete-variable approach to quantum information processing based on qubits. An overview of the usefulness and applications of squeezing will be given with an emphasis on the most recent developments.
