Abstract

A system and method for storing information in a quantum computer using a quantum storage ring. The method comprises cooling ions in the quantum storage ring to a low temperature; and binding the ions into a lattice structure, forming an ion Coulomb crystal.

Claims (26)

1. A method of storing information in a quantum computer using a quantum storage ring, the method comprising:

cooling ions in the quantum storage ring to a low temperature of about 5.15×10 −5 ° K; and

binding the ions into a lattice structure, forming an ion Coulomb crystal.

2. The method of claim 1 wherein the ions are cooled to a low temperature using one or more lasers.

3. The method of claim 1 further comprising reading and writing qubits to the storage ring.

4. A quantum storage ring, the quantum storage ring comprising:

a containment about 1 meter in diameter;

at least one laser for cooling ions in the storage ring such that thermal vibrations of ions are cooled to an extremely low temperature, so that the quantum states in motion of the ions are observable, and

electrodes adapted to be excited with RF signals.

5. The quantum storage ring of claim 4 further comprising four electrodes.

6. The quantum storage ring of claim 4 wherein the at least one laser comprises at least one of a Doppler and Raman laser.

7. The quantum storage ring of claim 4 wherein the at least one laser provides sideband cooling for confined ions.

8. The quantum storage ring of claim 4 further including a unit that allows for injection of the ion beam.

9. A quantum computer having a storage device, the storage device comprising:

a containment in the shape of a ring about 1 meter in diameter,

at least one laser for cooling ions in the storage ring such that thermal vibrations of ions are cooled to an extremely low temperature, so that the quantum states in motion of the ions are observable; and

four electrodes adapted to be excited with RF.

10. The quantum computer of claim 9 further includes read and write units coupled to and in communication with storage ring.

11. A quantum storage ring, the quantum storage ring comprising:

a containment about 1 meter in diameter;

read and write units coupled to and in communication with storage ring; and

electrodes adapted to be excited with RF signals.

12. The quantum storage ring of claim 11 further comprising four electrodes.

13. The quantum storage ring of claim 11 further including at least one laser for cooling ions in the storage ring such that thermal vibrations of ions are cooled to an extremely low temperature, so that the quantum states in motion of the ions are observable.

14. The quantum storage ring of claim 11 wherein the at least one laser comprises at least one of a Doppler and Raman laser.

15. The quantum storage ring of claim 11 wherein the at least one laser provides sideband cooling for confined ions.
