FEEDBACK IN QUANTUM COMMUNICATION [PDF]
International Journal of Quantum Information, 2005 In quantum communication, feedback may be defined in a number of distinct ways. An analysis of the effect feedback has on the rate information may be communicated is given, and a number of results and conjectures are stated.

Heliyon, 2021 We have experimentally created a robust, ultrabright and phase-stable polarization-entangled state close to maximally entangled Bell-state with %98-fidelity using the type-II spontaneous parametric down-conversion (SPDC) process in periodically-poled ...

Quantum computation by communication
New Journal of Physics, 2006 We present a new approach to scalable quantum computing--a ``qubus computer''--which realises qubit measurement and quantum gates through interacting qubits with a quantum communication bus mode. The qubits could be ``static'' matter qubits or ``flying'' optical qubits, but the scheme we focus on here is particularly suited to matter qubits.

Quantum Communication with Photons [PDF]
, 2016 The secure communication of information plays an ever increasing role in our society today. Classical methods of encryption inherently rely on the difficulty of solving a problem such as finding prime factors of large numbers and can, in principle, be cracked by a fast enough machine.

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 ...

Programming with Quantum Communication
Electronic Notes in Theoretical Computer Science, 2009 This work develops a formal framework for specifying, implementing, and analysing quantum communication protocols. We provide tools for developing simple proofs and analysing programs which involve communication, both via quantum channels and exhibiting the LOCC (local operations, classical communication) paradigm.

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

QUANTUM DISCORD AS A RESOURCE IN QUANTUM COMMUNICATION [PDF]
International Journal of Modern Physics B, 2012 As quantum technologies move from the issues of principle to those of practice, it is important to understand the limitations on attaining tangible quantum advantages. In the realm of quantum communication, quantum discord captures the damaging effects of a decoherent environment.
