When Non-Gaussian States are Gaussian: Generalization of Non-Separability Criterion for Continuous Variables
Whether a quantum state is entangled or not represents a very important question in quantum-information theory. Such knowledge reveals whether one can take advantage of the non-local properties of the state in quantum protocols such as quantum teleportation [1] and quantum cryptography [2]. This issue has been dealt with by many authors in recent years primarily in qubit systems where the Peres...
متن کاملQuantum Key Distribution using Continuous-variable non-Gaussian States
In this work we present a quantum key distribution protocol using continuous-variable nonGaussian states, homodyne detection and post-selection. The employed signal states are the Photon Added then Subtracted Coherent States (PASCS) in which one photon is added and subsequently one photon is subtracted. We analyze the performance of our protocol, compared to a coherent state based protocol, for...
متن کاملQuantum steering of Gaussian states via non-Gaussian measurements
Quantum steering-a strong correlation to be verified even when one party or its measuring device is fully untrusted-not only provides a profound insight into quantum physics but also offers a crucial basis for practical applications. For continuous-variable (CV) systems, Gaussian states among others have been extensively studied, however, mostly confined to Gaussian measurements. While the fulf...
متن کاملContinuous-variable Gaussian analog of cluster states
We present a continuous-variable CV Gaussian analog of cluster states, a new class of CV multipartite entangled states that can be generated from squeezing and quantum nondemolition coupling HI= XAXB. The entanglement properties of these states are studied in terms of classical communication and local operations. The graph states as general forms of the cluster states are presented. A chain for...
