Research topics
Massively multimode quantum memory
We constructed a DLCZ quantum memory in cold rubidium vapor which is equivalent to few thousand down-conversion sources. This may enable generation or arbitrary quantum states for quantum technologies, in particular communication and measurements.
Fast, Single photon sensitive camera
30kfps camera that we are working on may enable a number of multiphoton correlation experiments.
Experimental implementations of quantum-enhanced protocols
Execution and verification of theoretical designs by our colleagues.
