CE47 - Technologies quantiques

Iterative Generation of New quantum states of light for quantum Information processing – IGNITION

Submission summary

The main purpose of this project is to develop and exploit an all-optical quantum processor, able to chain a succession of operations on light pulses stored in a multi-register quantum memory. This device will allow the implementation of iterative protocols able to efficiently generate arbitrary quantum states of light. This project also includes a theoretical part, with the design of new protocols based on quantum control in order to do the best in terms of fidelity and complexity for the generated states. A main output of this project will be an analysis of the potentialities of such systems, with “realistic” experimental means based on existing or on short-term possible technologies, for efficient generation of GKP states in the optical domain. Such states could open new horizons in quantum information sciences: they would indeed allow an all-optical implementation of quantum gates, which could be an ideal way for scalable quantum computing, where several parts have to be connected.
