Operational entanglement-based quantum key distribution over 50 km of real-field optical fibres

Yoann Pelet, Grégory Sauder, Mathis Cohen +4

We present a real field quantum key distribution link based on energy-time entanglement. Three nodes are connected over the city of Nice by means of optical fibers with a total dis…

Experimental study of closed and open microwave waveguide graphs with preserved and partially violated time-reversal invariance

Weihua Zhang, Xiaodong Zhang, Jiongning Che +3

We report on experiments that were performed with microwave waveguide systems and demonstrate that in the frequency range of a single transversal mode they may serve as a model for…

Steady-state entanglement generation for non-degenerate qubits

Murilo H. Oliveira, Gerard Higgins, Chi Zhang +4

We propose a scheme to dissipatively produce steady-state entanglement in a two-qubit system, via an interaction with a bosonic mode. The system is driven into a stationary entangl…

Superradiant transfer of quantized orbital angular momentum between light and atoms in a ring trap

Nicola Piovella, Gordon R. M. Robb, Romain Bachelard

The orbital angular momentum (OAM) from a laser beam can be coherently transferred to a Bose-Einstein condensate in a ring trap, in quantized units of . The light-matter cou…
