QUANTIC COMPUTER BASED ON MAGNETIC QUBITS

摘要

Quantic computer based on magnetic cubits which consist of monodomain, nanometric, dielectric magnetic units (1), with a high ferromagnetic resonance quality factor, in a quantic superposition of the levels of the fundamental spin state and of the first excited spin state, operating in a milikelvins temperature range, each of the magnetic units (1) being deposited on a dielectric non magnetic substrate (6), inside an elementary quantic device (2) which incorporates a superconductor inductive element and a micro-SQUID sensor, and to which are associated superconductor lines (5). The quantic states of each qubit are manipulated and measured by sending and receiving electromagnetic signals to and from the corresponding quantic elementary device so that the quantic states of the various magnetic units are mixed/superposed by connecting said quantic element devices through superconductor lines (3) with switches of the Josephson union type (4).
