The Concept of a Quantum Edge Simulator: Edge Computing and Sensing in the Quantum Era.

Sensors, enabling observations across vast spatial, spectral, and temporal scales, are major data generators for information technology (IT). Processing, storing, and communicating this ever-growing amount of data pose challenges for the current IT infrastructure. Edge computing-an emerging paradigm to overcome the shortcomings of cloud-based computing-could address these challenges.

High-Fidelity Bell-State Preparation with ^{40}Ca^{+} Optical Qubits.

Entanglement generation in trapped-ion systems has relied thus far on two distinct but related geometric phase gate techniques: Mølmer-Sørensen and light-shift gates. We recently proposed a variant of the light-shift scheme where the qubit levels are separated by an optical frequency [B. C.

Iron-Catalyzed Tandem Three-Component Alkylation: Access to α-Methylated Substituted Ketones.

The borrowing hydrogen strategy has been applied in the synthesis of α-branched methylated ketones via a tandem three-component reaction catalyzed by a diaminocyclopentadienone iron tricarbonyl complex. Various alkyl and aromatic methyl ketones underwent dialkylation with various primary alcohols and methanol as alkylating agents in mild reaction conditions and good yields. Deuterium labeling experiments suggested that the benzylic alcohol was the hydrogen source in this tandem process.

Strengthening Government Leadership in Family Planning Programming in Senegal: From Proof of Concept to Proof of Implementation in 2 Districts.

Given Senegal's limited resources, the country receives substantial support from externally funded partner organizations to provide family planning and maternal and child health services. These organizations often take a strong and sometimes independent role in implementing interventions with their own structures and personnel, thereby bypassing the government district health system. This article presents findings from the Initiative Sénégalaise de Santé Urbaine (ISSU) (Senegal Urban Health Initiative) that assessed in 2 districts, Diamniadio and Rufisque, the extent to which it was feasible to create stronger government ownership and leadership in implementing a simplified package of family planning interventions from among those previously tested in other districts.

Noise reduction of a Libbrecht-Hall style current driver.

The Libbrecht-Hall circuit is a well-known, low-noise current driver for narrow-linewidth diode lasers. An important feature of the circuit is a current limit to protect the laser diode. As the current approaches the maximum limit, however, the noise in the laser current increases dramatically.
