  "abstract": "This work investigates the energy required to manipulate a memory bit using a superconducting vortex confined in a nanoscale double-well pinning potential. In the experiments, various double-well systems subjected to sinusoidal forces is explored, and the effects of both driving force and frequency is analyzed. Results reveal characteristic stochastic resonance behavior for weak drives and adiabatic manipulation at strong, low-frequency drives. Although our experimental method requires a steady sinusoidal drive incompatible with Landauer’s erasure protocol, our numerical analysis demonstrates that the work required for such bit manipulation (erasure) is within an order of magnitude of Landauer’s limit (\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$${k}_{B}T{{\\mathrm{ln}}}2$$\\end{document}kBTln2) at 4.2 K. These findings open possibilities for creating highly efficient memory elements that could be integrated with cryogenic quantum circuits or function as topological quantum computing qubits; thereby contributing to memory devices with lower energy consumption and mitigating the escalating global energy demand in the computing industry.",
