An introduction to one-way quantum computing in distributed architectures
This review provides a gentle introduction to one-way quantum computing in distributed architectures. One-way quantum computation shows significant promise as a computational model for distributed sys...  Discussion started by: Simon Benjamin

Estimating purity and entropy in stabilizer state experiments
Many experiments in quantum information aim at creating graph states. Quantifying the purity of an experimentally achieved graph state could in principle be accomplished using full-state tomography. T...  Discussion started by: Simon Benjamin

Distillation protocols enable generation of high quality entanglement even in the presence of noise. Existing protocols ignore the presence of local information in mixed states produced from some nois... Discussion started by: Simon Benjamin

We study the intrinsic computational power of entangled states exploited in measurement-based quantum computation. By focussing on the power of the classical computer that controls the measurements, w... Discussion started by: (anonymous)

We prove an area law for the entanglement entropy in gapped one dimensional quantum systems. The bound on the entropy grows surprisingly rapidly with the correlation length; we discuss this in terms o... Discussion started by: Tobias Osborne

We show that quantum mechanical entanglement can prevail in noisy open quantum systems at high temperature and far from thermodynamical equilibrium, despite the deteriorating effect of decoherence. Th... Discussion started by: Libby Heaney

We study the symmetric-side-channel-assisted private capacity of a quantum channel, for which we provide a single-letter formula. This capacity is additive, convex, and, for degradable channels, equal... Discussion started by: (anonymous)

We consider the problem of discriminating two different quantum states in the setting of asymptotically many copies, and determine the optimal strategy that minimizes the total probability of error. T... Discussion started by: Damian Abasto

In a recent paper [Phys. Rev. A 68, 033803 (2003)] experimental results on a double-slit configuration with two entangled bosons are presented. The authors argue that their data contradicts the de Bro... Discussion started by: Marco Genovese
