Reply to Comment on "Regional Versus Global Entanglement in Resonating-Valence-Bond States"
Dagomir Kaszlikowski, Aditi Sen De, Ujjwal Sen +1
In Phys. Rev. Lett. 99, 170502 (2007) (arXiv:quant-ph/0703227), we prove that resonating-valence-bond (RVB) states on arbitrary lattices possess genuine multiparty entanglement, an…
Non-locality of non-Abelian anyons
G. K. Brennen, S. Iblisdir, J. K. Pachos +1
Topological systems, such as fractional quantum Hall liquids, promise to successfully combat environmental decoherence while performing quantum computation. These highly correlated…
Bell-inequality test of spatial mode entanglement of a single massive particle
Libby Heaney, Janet Anders
Experiments showing the violation of Bell inequalities have formed our belief that the world at its smallest is genuinely non-local. While many non-locality experiments use the fir…
Positive phase space transformation incompatible with classical physics
Wonmin Son, Johannes Kofler, M. S. Kim +2
Bell conjectured that a positive Wigner function does not allow violation of the inequalities imposed by local hidden variable theories. A requirement for this conjecture is "when…
Second Quantized Kolmogorov Complexity
Caroline Rogers, Vlatko Vedral, Rajagopal Nagarajan
The Kolmogorov complexity of a string is the length of its shortest description. We define a second quantised Kolmogorov complexity where the length of a description is defined to…
Entanglement in doped Resonating Valence Bond states
Ravishankar Ramanathan, Dagomir Kaszlikowski, Marcin Wiesniak +1
We investigate the entanglement properties of resonating valence bond states on a two dimensional lattice in the presence of dopants that remove electrons from the lattice creating…
