Abstract

Apparatuses and systems for a die-integrated aspheric mirror are described herein. One apparatus includes an ion trap die including a number of ion locations and an aspheric mirror integrated with the ion trap die.

First claim

What is claimed:

1. An apparatus, comprising:
an ion trap die comprising a plurality of separate ion locations each configured to separately trap an ion in a potential well.

2. The apparatus of claim 1 , wherein:
the ion trap die comprises a longitudinal axis; and
the apparatus further comprises an aspheric mirror configured to be physically integrated with the ion trap die such that a principal axis of the aspheric mirror is substantially aligned with and perpendicular to the longitudinal axis of the ion trap die.

3. The apparatus of claim 1 , wherein:
the ion trap die comprises a horizontal axis; and
the apparatus further comprises an aspheric mirror configured to be physically integrated with the ion trap die such that a principal axis of the aspheric mirror is substantially aligned with the horizontal axis of the ion trap die.

4. The apparatus of claim 1 , further comprising:
an aspheric mirror physically integrated with the ion trap die; and
wherein the aspheric mirror is formed with an ellipsoidal configuration.

5. The apparatus of claim 4 , wherein:
a major axis of the ellipsoidal configuration is substantially parallel to a longitudinal axis of the ion trap die; and
a minor axis of the ellipsoidal configuration is substantially perpendicular to a horizontal axis of the ion trap die.

6. The apparatus of claim 1 , wherein the ion trap die and an aspheric mirror are both physically integrated with a substantially planar surface of a substrate die.

7. A die-integrated aspheric mirror system, comprising:
an ion trap die comprising a plurality of separate ion locations each configured to separately trap an ion in a potential well;
a first aspheric mirror physically integrated with the ion trap die; and
a first light source configured to promote emission of light by excitation of at least one ion trapped in the plurality of separate ion locations, wherein the first light source is positioned distal to the first aspheric mirror relative to the ion trap die.

8. The system of claim 7 , further comprising a number of apertures in the first aspheric mirror, wherein the first light source and the number of apertures are configured to aim light to promote emission of light from a particular ion location of the plurality of separate ion locations.

9. The system of claim 7 , wherein the first aspheric mirror is configured with a number of image locations between the first aspheric mirror and the ion trap die.

10. The system of claim 7 , wherein the first aspheric mirror is configured to focus light emitted from a particular ion location of the plurality of separate ion locations toward at least one designated optical fiber.

11. The system of claim 10 , further comprising a nub on the at least one designated optical fiber toward which the light is focused,
wherein the nub is configured to collect the light reflected at various angles by the first aspheric mirror having a numerical aperture corresponding to the various angles to enable coupling with the reflected light.

12. The system of claim 7 , further comprising:
the ion trap die, the first aspheric mirror, and a first number of optical fibers all being physically integrated with a substantially planar surface of an underlying interposer die;
wherein a longitudinal axis and a horizontal axis of the ion trap die forms a plane that is substantially parallel with the substantially planar surface of the underlying interposer die;
wherein longitudinal axes of the first number of optical fibers are perpendicular to the substantially planar surface of the underlying interposer die;
wherein the first aspheric mirror is embedded into the substantially planar surface of the underlying interposer die along an axis substantially perpendicular to a principal axis of the first aspheric mirror; and
wherein the ion trap die, the first aspheric mirror, a number of apertures in the first aspheric mirror, the first number of optical fibers, and the substantially planar surface of the underlying interposer die are configured to enable unobstructed optical access to the plurality of separate ion locations by light from the first light source.

13. The system of claim 7 , further comprising:
a second aspheric mirror physically integrated with the ion trap die, wherein the second aspheric mirror is on an opposite side of the ion trap die relative to the first aspheric mirror;
a second light source configured to promote emission of light by excitation of at least one ion trapped in the plurality of separate ion locations; and
a second number of optical fibers positioned between the second aspheric mirror and the ion trap die, wherein the second number of optical fibers is configured to collect light reflected by the second aspheric mirror that was emitted from the plurality of separate ion locations.

14. The system of claim 13 , wherein:
the first aspheric mirror and the second aspheric mirror each have a major axis positioned substantially parallel to a longitudinal axis of the ion trap die, wherein the first aspheric mirror and second aspheric mirror have opposing reflective surfaces; and
the first aspheric mirror has a first circumference and the second aspheric mirror has a second circumference, wherein the first circumference has at least an arc thereof that is separated by a distance from an opposing arc of the second circumference.

15. The system of claim 14 , wherein the distance by which the first circumference and the second circumference are separated enables unobstructed optical access to the ion trap die by at least one of a charge-coupled device camera and a third light source.

16. A die-integrated aspheric mirror system, comprising:
an ion trap die comprising a plurality of separate ion locations each configured to separately trap an ion in a potential well;
a first aspheric mirror physically integrated with the ion trap die; and
a first plurality of optical fibers positioned between the first aspheric mirror and the ion trap die to collect light.

17. The system of claim 16 , wherein:
determination of a particular ion location comprises a focus of light on a particular optical fiber determined by an appropriate combination of a configuration of a reflective surface of the first aspheric mirror and angular orientations to the reflective surface of a position of the particular optical fiber and a position of the particular ion location.

18. The system of claim 16 , further comprising:
a plurality of apertures in the first aspheric mirror, wherein a light source and the plurality of apertures are configured to simultaneously aim light to promote substantially simultaneous emission of light from the plurality of separate ion locations; and
memory having executable instructions to be executed by a processor:
determine a particular ion location from which the light was emitted by each of the first plurality of optical fibers being positioned to collect light focused thereon by the first aspheric mirror; and
to determine the particular ion locations from which the light was substantially simultaneously emitted.
