Modular tunable coupler for superconducting qubits

The development of modular and versatile quantum interconnect hardware is a key next step in the scaling of quantum information platforms to larger size and greater functionality. For superconducting quantum systems, fast and well-controlled tunable circuit couplers will be paramount for achieving high fidelity and resource efficient connectivity, whether for performing two-qubit gate operations, encoding or decoding a quantum data bus, or interfacing across modalities. Here we propose a versatile and internally-tunable double-transmon coupler (DTC) architecture that implements tunable coupling via flux-controlled interference in a three-junction dcSQUID. Crucially, the DTC possesses an internally defined zero-coupling state that is independent of the coupled data qubits or circuit resonators. This makes it particular attractive as a modular and versatile design element for realizing fast and robust linear coupling in several applications such as high-fidelity two-qubit gate operations, qubit readout, and quantum bus interfacing

Common snook fed in alternate and continuous regimens with diet supplemented with Bacillus subtilis probiotic.

The objective of this work was to evaluate the addition of Bacillus subtilis probiotic to the feed of common snook (Centropomus undecimalis) fingerlings, in alternate and continuous regimens. Six hundred and sixty fish, with verage length of 5.90±0.88 cm and weight of 1.92±0.28g, were stocked in 12 cages of 1.0 m 3 , with 55 fish each. The experimental design was completely randomized, with three treatments and four replicates. The treatments consisted of diet with the addition of probiotic, provided in alternate regimen for 7 days and in continuous regimen; besides a control without probiotic in the feed. Zootechnical performance, body composition, immune response, and blood parameters were evaluated. No significant differences were observed in zootechnical performance indexes and in body composition of fish treated with probiotic, when compared to the control. Fish from the alternate regimen showed an increment in respiratory burst and a lower total erythrocyte count than fish from the continuous regimen and the control. Fish from the continuous regimen did not differ from those of the control. The addition of Bacillus subtilis does not increase growth rates of common snook fingerlings; however, it has an immunostimulant action when supplied in alternate regimen.Título em português: Robalo?flecha alimentado em regimes alternado e contínuo com dieta suplementada com o probiótico Bacillus subtilis

Número de amostras simples de solo para avaliação da fertilidade em alguns ecossistemas amazônicos.

A analise dos solos das areas de mata, mata recem queimada e pastagem de Brachiaria humidicola teve por finalidade determinar o numero minimo de amostras de solo necessarias para perfazer uma amostra composta, que seja representativa para fins de analise da fertilidade do solo. As areas amostradas acham-se estabelecidas em Latossolo Amarelo muito argiloso e com relevo suave-ondulado. Os resultados mostraram ser necessario coletar, na profundidade de 0cm-20cm seis, sub-amostras para areas de mata, 64 para areas de mata recem queimada e 43 para areas de pastagens para obtencao de uma amostra composta representativa a um nivel de 95% de probabilidade estatistica.bitstream/item/75885/1/CPAA-BOL.-PESQ.-4-84.pd
