Proposal for Quantum Simulation via All-Optically Generated Tensor Network States

We devise an all-optical scheme for the generation of entangled multimode photonic states encoded in temporal modes of light. The scheme employs a nonlinear down-conversion process in an optical loop to generate one- and higher-dimensional tensor network states of light. We illustrate the principle with the generation of two different classes of entangled tensor network states and report on a variational algorithm to simulate the ground-state physics of many-body systems. We demonstrate that state-of-the-art optical devices are capable of determining the ground-state properties of the spin-1/2 Heisenberg model. Finally, implementations of the scheme are demonstrated to be robust against realistic losses and mode mismatch.Comment: 6 pages main text plus 6 pages Supplementary Material and many figures.

Colour discrimination and attention.

<p>The comorbidity of ADHD+CTD is characterized by additive effects on colour discrimination and attention. The Farnsworth-Munsell 100 hue colour discrimination test (above) revealed for ADHD and CTD additive effects on error scores (confidence intervals with p = .05) of the blue-yellow (left) and red-green (right) axis. Difficulties with sustained attention in the Frankfurt Attention Inventory as indicated by the number (FAIR-L, below left, confidence intervals with p = .05) and proportion (FAIR-Q, below right) of attentively processed items during the 6 min testing are present in children with ADHD but not CTD.</p
