Experimental optical phase measurement approaching the exact Heisenberg limit
Nature Communications, 2018 Measurements of an unknown optical phase have not yet been performed with the ultimate precision, i.e. saturating the Heisenberg limit. Here, Daryanoosh et al.

On the equivalence between squeezing and entanglement potential for two-mode Gaussian states
Scientific Reports, 2023 The maximum amount of entanglement achievable under passive transformations by continuous-variable states is called the entanglement potential. Recent work has demonstrated that the entanglement potential is upper-bounded by a simple function of the ...

Advanced Photonics 2018 (BGPP, IPR, NP, NOMA, Sensors, Networks, SPPCom, SOF), 2018 Quantum Communication is the art of transferring an unknown quantum state from one location, Alice, to a distant one, Bob. This is a non-trivial task because of the quantum no-cloning theorem which prevents one from merely using only classical means.

Substituting Quantum Entanglement for Communication [PDF]
, 1997 We show that quantum entanglement can be used as a substitute for communication when the goal is to compute a function whose input data is distributed among remote parties.

Experimental Implementation of Enhanced Security Coherent One-Way Quantum Key Distribution
IEEE AccessCoherent One-Way (COW) is a simple and widely utilized quantum key distribution (QKD) protocol, favored in both experimental and commercial applications. In this paper, we compare the information that an eavesdropper, Eve, can acquire in both the 2-decoy

Hierarchical quantum communication
, 2013 A general approach to study the hierarchical quantum information splitting (HQIS) is proposed and the same is used to systematically investigate the possibility of realizing HQIS using different classes of 4-qubit entangled states that are not connected ...

Strong converse for the quantum capacity of the erasure channel for almost all codes [PDF]
, 2014 A strong converse theorem for channel capacity establishes that the error probability in any communication scheme for a given channel necessarily tends to one if the rate of communication exceeds the channel's capacity.
