QUROPE Quantum Information Processing and Communication in Europe

COQUIT aims at designing quantum algorithms that can be implemented in terms of operations that are easily feasible on many particle quantum states and to investigate quantum devices with limited control. Instead of improving the corresponding experimental methods, CQOUIT aims at a systematic study of the tasks which can be performed with currently available techniques.

1. Developing quantum technologies based on atomic, molecular and optical (AMO) systems both for scalable quantum computation as well as entanglement-enabled technologies (like metrology and sensing)

• Probability

In this work, the authors show how random numbers can be generated in a certified manner using the non-local correlation of entangled quantum states. The randomness of the generated symbols is private and device-independent. Moreover, they perform an experimental proof-of-principle realization of the theoretical formalism.
