Measurement based 2-qubit unitary gates for pairs of Nitrogen-Vacancy centers in diamond [PDF]
Phys. Rev. A 98, 052342 (2018), 2018 The implementation of a high-fidelity two-qubit quantum logic gate remains an outstanding challenge for isolated solid-state qubits such as Nitrogen-Vacancy (NV) centers in diamond. In this work, we show that by driving pairs of NV centers to undergo photon scattering processes that flip their qubit state simultaneously, we can achieve a unitary two ...

Digestible tryptophan requirements of meat quails in the growth phase
Revista Brasileira de Zootecnia, 2012 The objective of this experiment was to estimate the digestible tryptophan (DTrp) requirements for growing meat quails. In the first experiment (1-14 days of age), 1,950 quails were distributed in a completely randomized design, with six levels of DTrp ...

Generation and complete nondestructive analysis of hyperentanglement assisted by nitrogen-vacancy centers in resonators [PDF]
Phys. Rev. A 91, 062321 (2015), 2015 We present two efficient schemes for the deterministic generation and the complete nondestructive analysis of hyperentangled Bell states in both the polarization and spatial-mode degrees of freedom (DOFs) of two-photon systems, assisted by the nitrogen-vacancy (NV) centers in diamonds coupled to microtoroidal resonators as a result of cavity quantum ...

AgronomyProtection of high-yielding winter wheat (WW) with fungicides increases the productivity of nitrogen (N) present in the soil–crop system during the growing season. As a consequence of the action of fungicides, the nitrogen gap (NG) reduces.

Colimitation of light and nitrogen on algal growth revealed by an array microhabitat platform [PDF]
arXiv, 2023 Microalgae are key players in the global carbon cycle and emerging producers of biofuels. Algal growth is critically regulated by its complex microenvironment, including nitrogen and phosphorous levels, light intensity, and temperature. Mechanistic understanding of algal growth is important for maintaining a balanced ecosystem at a time of climate ...

A Nitrogen Balance for Austria
Water Science and Technology, 1992 The mass flux approach is a good tool to tell whether decisions in pollution control to be taken or already taken are adequate. In policy making, the boundaries for the mass flux approach can be either national borders or catchment areas of river basins.

Animals, 2022 The aim of this study was to evaluate the effect of replacing Tifton-85 hay (Cynodon spp. cv. Tifton 85) with 0, 150, 300, 450 and 600 g/kg dry matter (DM) of spineless cactus (SC, Nopalea cochenilifera Salm-Dyck) plus urea and ammonium sulfate (UAS; 9:1)
