Open AccessMultipartite entanglement of billions of motional atoms heralded by single photon
Quantum theory does not prevent entanglement from being created and observed in macroscopic physical systems, in reality however, the accessible scale of entanglement is still very limited due to decoherence e...

Open AccessDirect observation of broadband nonclassical states in a room-temperature light–matter interface
Nonclassical state is an essential resource for quantum-enhanced communication, computing and metrology to outperform their classical counterpart. The nonclassical states that can operate at high bandwidth and...
