Qubit complexity of continuous problems

The number of qubits used by a quantum algorithm will be a crucial computational resource for the foreseeable future. We show how to obtain the classical query complexity for continuous problems. We then establish a simple formula for a lower bound on the qubit complexity in terms of the classical query complexity.

On the use of O2 spin-rotation lines for elevation angle calibration of atmospheric thermal emission spectra

The magnetic dipole-allowed spin-rotation lines of O₂ potentially can be used for pointing calibration and confirmation of float altitude for far infrared spectra of the stratosphere obtained from balloon platforms. We demonstrate that current deficiencies in the spectroscopic database, particularly the air pressure-broadening coefficients, severely limit the capability of deriving useful pointing calibrations, and that precise pressure-broadening measurements for the transitions actually used in calibration are needed to improve this capability.     

The spectrophotometric determination of uranium by the 1-pyrrolidinecarbodithioate method

Summary A spectrophotometric method for the determination of uranyl ion is proposed which is based on the use of ammonium 1-pyrrolidinecarbodithioate as the chromogenic reagent. Conformity to Beer's law was observed for the range between 0 to 50 ppm of uranium when spectrophotometric measurements are made at 385 nm.
