Near-capacity code design for entanglement-assisted classical communication over quantum depolarizing channels
No full textWe have conceived a near-capacity code design for entanglement-assisted classical communication over the quantum depolarizing channel. The proposed system relies on efficient near-capacity classical code designs for approaching the entanglement-assisted classical capacity of a quantum depolarizing channel. It incorporates an Irregular Convolutional Code (IRCC), a Unity Rate Code (URC) and a soft-decision aided Superdense Code (SD), which is hence referred to as an IRCC-URC-SD arrangement. Furthermore, the entanglement-assisted classical capacity of an N-qubit superdense code transmitted over a depolarizing channel is invoked for benchmarking. It is demonstrated that the proposed system operates within 0.4 dB of the achievable noise limit for both 2-qubit as well as 3-qubit SD schemes. More specifically, our design exhibits a deviation of only 0.062 and 0.031 classical bits per channel use from the corresponding 2-qubit and 3-qubit capacity limits, respectively. The proposed system is also benchmarked against the classical convolutional and turbo codes

Simplicial <i>G</i>-complexes and representation stability of polyhedral products
No full textRepresentation stability in the sense of Church and Farb is concerned with stable properties of representations of sequences of algebraic structures, in particular of groups. We study this notion on objects arising in toric topology. With a simplicial G–complex K and a topological pair (X, A), a G–polyhedral product (X, A)
K is associated. We show that the homotopy decomposition of Σ(X,A)
K is then G–equivariant after suspension. In the case of †Σ
m–polyhedral products, we give criteria on simplicial Σ
m–complexes which imply representation stability of Σ
m–representations {H

Pleurocystidia 32–67 × 8–18 μm, sparse, subfusoid to broadly ventricose, sometimes with long beaks, thin-walled. Hymenophoral trama phylloporoid with hyphae of the lateral strata touching or almost touching each other; hyphae subcylindrical to cylindrical, 5–15 μm wide. Pileipellis an intricate trichoderm, about 400 μm thick, composed of entangled filamentous hyphae 6–12 μm wide, thin-walled, with subcylindrical to subclavate terminal cells 28–78 × 5–10 μm, thin-walled. Pileal trama composed of interwoven hyphae 5–13 μm wide. Stipitipellis about 150 μm thick, hyphohymeniform with clavate to cystidioid terminal cells (18.0–45.0 × 8.5–14.0 μm) in the inner layer and narrow cylindrical terminal cells (25.0–56.0 × 4.5–7.5 μm) in the outter layer. Stipe trama composed of longitudinally arranged parallel thin-walled hyphae 5–20 μm wide. Clamp connections absent. Ecology, habitat and distribution:—On soil in broad-leaved forests dominated by Fagaceae trees (Lithocarpus spp., Castanopsis spp., etc.) mixed with fir, waxberry and bamboos. China. June to August. Currently only known in southeast Yunnan of China. Other specimen examined:— CHINA.
