  2. Whatis Quantum Computers? A quantum computer is a device based on quantum magnets for computation that makes direct use of quantum mechanical phenomena, such as superposition and entanglement, to perform operations on data. Richard Feynman 1982 A quantum computer maintains a sequence of qubits But what can we used as qubits? 1

  16. Оборудование Superconducting Quantum Interference Device (SQUID) ac-susceptibility data were recorded using an ultra-high resolution ac-susceptometeradapted to a 3He-4He top-loading dilution refrigerator. The compensated-coil susceptometer is optimized for measuring small single crystals in the mg range. The system is equipped with a 12 T superconducting magnet. χac Nonius Kappa CCD (Mo kα, μ = 0.71073 Å) diffractometerequippedwith a graphitemonochromator.
