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…
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…
Phase variance of squeezed vacuum states
Emilio Bagan, Alex Monras, Ramon Munoz-Tapia
We consider the problem of estimating the phase of squeezed vacuum states within a Bayesian framework. We derive bounds on the average Holevo variance for an arbitrary number o…
