Fundamental limitations to key distillation from Gaussian states with Gaussian operations
Ludovico Lami, Ladislav Mišta, Gerardo Adesso
We establish fundamental upper bounds on the amount of secret key that can be extracted from quantum Gaussian states by using only local Gaussian operations, local classical proces…
Verifying genuine multipartite entanglement of the whole from its separable parts
Michal Mičuda, Robert Stárek, Jan Provazník +2
We prove experimentally the predicted existence of a three-qubit quantum state with genuine multipartite entanglement which can be certified solely from its separable two-qubit red…
Multipartite Einstein-Podolsky-Rosen steering sharing with separable states
Yu Xiang, Xiaolong Su, Ladislav Mišta +2
Distribution of quantum correlations among remote users is a key procedure underlying many quantum information technologies. Einstein-Podolsky-Rosen steering, which is one kind of…
Gaussian intrinsic entanglement
Ladislav Mišta, Richard Tatham
We introduce a cryptographically motivated quantifier of entanglement in bipartite Gaussian systems called Gaussian intrinsic entanglement (GIE). The GIE is defined as the optimize…
Experimental demonstration of a fully inseparable quantum state with nonlocalizable entanglement
M. Mičuda, D. Koutný, M. Miková +3
Localizability of entanglement in fully inseparable states is a key ingredient of assisted quantum information protocols as well as measurement-based models of quantum computing. W…
Entangling the whole by beam splitting a part
Callum Croal, Christian Peuntinger, Vanessa Chille +4
A beam splitter is a basic linear optical element appearing in many optics experiments and is frequently used as a continuous-variable entangler transforming a pair of input modes…
