Abstract

A single cell apparatus and method for single ion addressing are described herein. One apparatus includes a single cell configured to set a frequency, intensity, and a polarization of a laser, shutter the laser, align the shuttered laser to an ion in an ion trap such that the ion fluoresces light and/or performs a quantum operation, and detect the light fluoresced from the ion.

First claim

What is claimed:

1 . An apparatus for single ion addressing, comprising:
a single cell configured to:
set a frequency, intensity, and a polarization of a laser;
shutter the laser;
align the shuttered laser to an ion in an ion trap such that the ion fluoresces light and/or performs a quantum operation; and
detect the light fluoresced from the ion.

2 . The apparatus of claim 1 , wherein the single cell is completely inside a vacuum.

3 . The apparatus of claim 1 , wherein the single cell is partially inside a vacuum.

4 . The apparatus of claim 1 , wherein the single cell includes an electro-optic modulator configured to prepare a state of the laser.

5 . The apparatus of claim 1 , wherein the single cell includes:
an acousto-optic modulator configured to set the frequency and intensity of the laser and shutter the laser; and a Pockels cell configured to set the polarization of the laser.

6 . The apparatus of claim 1 , wherein the single cell includes an array of photo-multiplier tubes configured to detect the light fluoresced from the ion.

7 . A method for single ion addressing, comprising:
preparing a state of a laser using a single cell; shuttering the laser using the single cell; aligning the shuttered laser to an ion in an ion trap using the single cell such that the ion fluoresces light and/or performs a quantum operation; and detecting the light fluoresced from the ion using the single cell.

8 . The method of claim 7 , wherein aligning the shuttered laser to the ion in the ion trap using the single cell includes:
focusing the shuttered laser and directing the shuttered laser at a mirror of the single cell using a lens of the single cell; and directing the shuttered laser at the ion in the ion trap using the mirror of the single cell.

9 . The method of claim 7 , wherein the method includes terminating the shuttered laser using the single cell after aligning the shuttered laser to the ion in the ion trap.

10 . The method of claim 7 , wherein the method includes splitting the laser into a plurality of components before preparing the state of the laser and shuttering the laser.

11 . The method of claim 10 , wherein:
preparing the state of the laser includes preparing the state of a single one of the plurality of components of the laser; shuttering the laser includes shuttering the single one of the plurality of components of the laser; and aligning the shuttered laser to the ion in the ion trap includes aligning the shuttered component of the laser.

12 . The method of claim 7 , wherein the laser is a Doppler cooling laser.

13 . The method of claim 7 , wherein the laser is a quantum operation laser.

14 . An apparatus for single ion addressing, comprising:
a vacuum; and a single cell inside the vacuum and configured to:
set a frequency and a polarization of a laser;
shutter the laser;
align the shuttered laser to an ion in an ion trap such that the ion fluoresces light and/or performs a quantum operation; and
detect the light fluoresced from the ion.

15 . The apparatus of claim 14 , wherein the single cell includes:
a first lens configured to focus the shuttered laser; a mirror configured to direct the focused shuttered laser at the ion in the ion trap such that the ion fluoresces light; and a second lens configured to receive the light fluoresced from the ion.

16 . The apparatus of claim 15 , wherein the single cell includes an additional mirror configured to direct the laser at a beam dump after the laser is focused at the ion in the ion trap.

17 . The apparatus of claim 14 , wherein:
the apparatus includes a fiber bundle configured to split the laser into a plurality of fibers before the laser enters the vacuum; and a single one of the fibers enters the single cell.

18 . The apparatus of claim 14 , wherein the apparatus includes a single fiber exiting the single cell.

19 . The apparatus of claim 18 , wherein the apparatus includes a fiber bundle configured to bundle the single fiber with a number of other fibers.

20 . The apparatus of claim 14 , wherein the apparatus includes a plurality of fibers entering and exiting the single cell.
