Overcoming fundamental bounds on quantum conference key agreement
Giacomo Carrara, Gláucia Murta, Federico Grasselli
Twin-Field Quantum Key Distribution (TF-QKD) enables two distant parties to establish a shared secret key, by interfering weak coherent pulses (WCPs) in an intermediate measuring s…
Squeezing as a resource to counteract phase diffusion in optical phase estimation
Giacomo Carrara, Marco G. Genoni, Simone Cialdi +2
We address a phase estimation scheme using Gaussian states in the presence of non-Gaussian phase noise. At variance with previous analysis, we analyze situations in which the noise…
Genuine multipartite entanglement is not a precondition for secure conference key agreement
Giacomo Carrara, Hermann Kampermann, Dagmar Bruß +1
Entanglement plays a crucial role in the security of quantum key distribution. A secret key can only be obtained by two parties if there exists a corresponding entanglement-based d…
