Quantum-to-classical rate distortion coding
Nilanjana Datta, Min-Hsiu Hsieh, Mark M. Wilde +1
We establish a theory of quantum-to-classical rate distortion coding. In this setting, a sender Alice has many copies of a quantum information source. Her goal is to transmit class…
The structure of multidimensional entanglement in multipartite systems
Marcus Huber, Julio I. de Vicente
We explore the structure of multipartite quantum systems which are entangled in multiple degrees of freedom. We find necessary and sufficient conditions for the characterization of…
Relation between semi- and fully-device-independent protocols
Hong-Wei Li, Piotr Mironowicz, Marcin Pawlowski +7
We study the relation between semi and fully device independent protocols. As a tool, we use the correspondence between Bell inequalities and dimension witnesses. We present a meth…
Dimension witnesses and quantum state discrimination
Nicolas Brunner, Miguel Navascués, Tamás Vértesi
Dimension witnesses allow one to test the dimension of an unknown physical system in a device-independent manner, that is, without placing assumptions about the functioning of the…
Genuinely Multipartite Concurrence of N-qubit X-matrices
S. M. Hashemi Rafsanjani, M. Huber, C. J. Broadbent +1
We find an algebraic formula for the N-partite concurrence of N qubits in an X-matrix. X- matricies are density matrices whose only non-zero elements are diagonal or anti-diagonal…
Closing the detection loophole in multipartite Bell tests using GHZ states
Karoly F. Pal, Tamas Vertesi, Nicolas Brunner
We investigate the problem of closing the detection loophole in multipartite Bell tests, and show that the required detection efficiencies can be significantly lowered compared to…
