We present a hardware agnostic error mitigation algorithm for near term quantum processors inspired by the classical Lanczos method. This technique can reduce impact of different sources noise at sole cost an increase in number measurements to be performed on target circuit, without additional experimental overhead. demonstrate through numerical simulations and experiments IBM Quantum that prop...

In this work, the current stability is discussed for cosmic strings with bosonic superconductivity. A non-vanishing curvature of string generally induce quantum instability current-carrying particle. Its decay rates are explored various types model parameters, curved shapes, and processes. As a cosmological application, examined superconducting in network also vortons by evaluating their evolut...

We present measurements of temperature and magnetic-field dependence of the critical current and excess current in a carbon nanotube Josephson quantum dot junction. The junction is fabricated in a controlled environment which allows for extraction of the full critical current. The measurements are performed in the open quantum dot regime and fitted to theory with good qualitative agreement. We ...

This study was designed to compute the spectroscopic properties of aniline family, and educates the 3chloro-4-fluoro-aniline, which have unique pharmaceutical important. The structural and spectroscopic properties were investigated using a quantum calculation. The density functional theory approach at B3LYP/6–31G(d) data set is apply. IR and UV-Visible spectrophotometric estimated through GAMES...
