Flux Qubit Based on Hybrid Ferromagnetic-Superconducting Device

  title={Flux Qubit Based on Hybrid Ferromagnetic-Superconducting Device},
  author={Filipp N. Rybakov and Egor Babaev},
One of the promising strategy to realize a quantum bit is based on creation of a superposition of circulating currents in a superconducting device [1, 2, 3, 4, 5, 6]. Such qubit realization, termed “flux qubit” is realized by creating a superconducting loop subject to external magnetic field (Fig. 1a). When the loop encloses (nearly) half of the superconducting flux quantum, Φ ≈ 12Φ0, there is an energy near degeneracy of clock-wise (CW) and counter-clockwise (CCW) circulation of…
