We present the design, construction, calibration, and software development of a temperature monitoring system for resistance standards. The system supports 19
This paper addresses the performance of polar codes in the context of the quantum key distribution (QKD) protocol. It introduces the notion of an interactive
The numerical coefficients linearly relating the effects of stress (including pressure), temperature, and composition to shifts in the energies of the Cr
Rigorous calculation of the Poynting correction, which describes the effect of pressure on the fugacity of a condensed phase, requires time-consuming evaluation
