TL;DR: The sensitivity of the high precision phase estimation method is equivalent to resolving light pulses of the order of a attosecond and it is robust against chromatic dispersion.

TL;DR: In this article, two different probabilistic teleportations of a two-particle entangled state by pure entangled threeparticle state are shown, and their successful probabilities are different.

TL;DR: For the first time, an eight-photon entangled-state state with a measured fidelity of 0.59±0.02 is demonstrated, which proved the presence of genuine eight-partite entanglement.

TL;DR: In this article, a new protocol for distributing keys in a quantum network overcomes theoretical bounds for key transmission rates, potentially enabling the implementation of secure communication in large networks in large quantum networks.

TL;DR: This work experimentally demonstrates a reconfigurable non-reciprocal device with alternative functions as either a circulator or a directional amplifier via optomechanically induced coherent photon–phonon conversion or gain, which offers exciting opportunities for combining reconfigurability, non-Reciprocity and active properties in single photonic devices, which can be generalized to microwave and acoustic circuits.
