Towards quantum key distribution with noisy communication sources
Adam Walton, Anne Ghesquière, David Jennings +1
A beam emitted by a displaced thermal source, incident on a beam splitter, is used as the source in a central broadcast quantum key distribution protocol. These displaced thermal s…
Quantum Secrecy in Thermal States III
Anne Ghesquiere, Benjamin T. H. Varcoe
In this paper we expanded the security of a central broadcast protocol using thermal states to the case in which the eavesdropper controls the source. Quantum secrecy in a continuo…
Quantum Secrecy in Thermal States II
Elizabeth Newton, Anne Ghesquière, Freya L. Wilson +2
In this paper we consider a scheme for cryptographic key distribution based on a variation of continuous variable quantum key distribution called central broadcast. In the continuo…
Quantum Secrecy in Thermal States
Elizabeth Newton, Anne Ghesquière, Freya L. Wilson +2
We propose to perform quantum key distribution using quantum correlations occurring within thermal states produced by low power sources such as LED's. These correlations are exploi…
Dynamics and non-equilibrium steady state in a system of coupled harmonic oscillators
A. Ghesquière, I. Sinayskiy, F. Petruccione
A system of two coupled oscillators, each of them coupled to an independent reservoir, is analysed. The analytical solution of the non-rotating wave master equation is obtained in…
Entanglement in a Bipartite Gaussian State
Anne Ghesquière
To examine the loss of entanglement in a two-particle Gaussian system, we couple it to an environment and use the Non-Rotating Wave master equation to study the system's dynamics.…
