| 简介 |
The present invention discloses an universal quantum computing system using electro-nuclear wavefunctions of rare-earth ions, comprising : a) a 2d-matrix of rare-earth ions being embedded in an insulating solid state matrix, wherein : b) each rare-earth ion representing a nuclear qubit that can be selectively operated as a passive qubit or as an active qubit; c) said passive qubit being represented by a passive electronic doublet at a non-degenerate ground state thereby storing the quantum information in the two different nuclear pin states possible in this non-degenerate ground state causing two different passive-state electro-nuclear wavefunctions, and d) said active qubit being represented by an active electronic doublet at a non-degenerate excited state thereby storing the quantum information in the two different nuclear pin states possible in this non-degenerate excited state causing to different active-state electro-nuclear wavefunctions, and e) a laser source for selectively generating laser pulses in order to optically excite the rare-earth ions from the non- degenerated ground state into the non-degenerate excited state and vice versa, thereby locally controlling the electronic dipolar interaction in a tunable manner among at least two active qubits, and f) an external electrical field in form of switchable electric gates for inducing a Stark shift for a selectable qubit, and g) an external magnetic field. |
