Paper Abstract

Various variants of use high-sensitivity superconducting quantum interferometers (SQUID) in problems closely connected with development of a quantum computer are considered. 1.Hardware realization of a method of definition of midget concentration of the paramagnetic centers, based on measurement of their magnetization SQUID in a mode of modulation microwave saturation of magnetic sublevels is offered. The method will allow make testing of semi-conductor materials necessary for creation of a spin solid-state quantum computer. 2.The opportunity of application SQUID for reading a condition of the quantum register, based on the quantum-statistical mechanism, allowing registered a state of single spin, is considered. 3.The circuit super low noise the quantum electrometer, based on use SQUID is offered as a measuring instrument of magnetization of spin system in which exchange interaction is adjusted by potential on in parallel connected managing electrodes (on type a spin ensemble computer).
