Bell inequalities with no quantum violation and unextendible product bases
R. Augusiak, J. Stasińska, C. Hadley +3
The strength of classical correlations is subject to certain constraints, commonly known as Bell inequalities. Violation of these inequalities is the manifestation of nonlocality--…
Device-independent tests of classical and quantum dimensions
Rodrigo Gallego, Nicolas Brunner, Christopher Hadley +1
We address the problem of testing the dimensionality of classical and quantum systems in a `black-box' scenario. We develop a general formalism for tackling this problem. This allo…
Unified Framework for Correlations in Terms of Local Quantum Observables
A. Acín, R. Augusiak, D. Cavalcanti +5
We provide a unified framework for nonsignalling quantum and classical multipartite correlations, allowing all to be written as the trace of some local (quantum) measurements multi…
Single-copy entanglement in a gapped quantum spin chain
Christopher Hadley
The single-copy entanglement of a given many-body system is defined [J. Eisert and M. Cramer, Phys. Rev. A. 72, 042112 (2005)] as the maximal entanglement deterministically distill…
Decoherence-based exploration of d-dimensional one-way quantum computation
M. S. Tame, M. Paternostro, C. Hadley +2
We study the effects of amplitude and phase damping decoherence in d-dimensional one-way quantum computation (QC). Our investigation shows how information transfer and entangling g…
Boundary effects to the entanglement entropy and two-site entanglement of the spin-1 valence-bond solid
Heng Fan, Vladimir Korepin, Vwani Roychowdhury +2
We investigate the von Neumann entropy of a block of subsystem for the valence-bond solid (VBS) state with general open boundary conditions. We show that the effect of the boundary…
