[0019] Exemplary ion trap apparatus

[0020] Figure 1 A perspective view is provided of an exemplary embodiment of an ion trap device and / or package 100. In various embodiments, ion trap device and / or package 100 includes an ion trap chip 108 having an ion trap 110 defined thereby and / or thereon. Figures 3 to 5At least a portion of some exemplary ion traps 110 are shown from a top view. In various embodiments, the ion trap 110 is a surface ion trap. In various embodiments, the ion trap device and / or package 100 includes an ion trap chip 108 having an ion trap 110 defined by and / or at least in part by a plurality of radio frequency (RF) rails 112 (e.g., 112A, 112B) thereon. In various embodiments, the ion trap device and / or package 100 includes an ion trap 110 defined at least in part by a plurality of sequences 114 (e.g., 114A, 114B, 114C) of TT electrodes. In an exemplary embodiment, the ion trap 110 is a surface Paul trap with symmetrical RF rails. In various embodiments, the upper surface of the ion trap 110 has a flattened topology. For example, the upper surface of each RF rail 112 in the plurality of RF rails 112 and the upper surface of each TT electrode 116 (e.g., 116A, 116B, 116C), 118 (e.g., 118A, 118B, 118C) in the plurality of sequences 114 of TT electrodes may be substantially coplanar. For example, in an exemplary embodiment, the thickness of the RF rail 112 and the TT electrodes 116, 118 (e.g., in the z-direction) is approximately equal. In an exemplary embodiment, the thickness of the RF rail 112 and / or the TT electrodes 116, 118 is in the range of approximately 0.1 μm-20 μm. For example, the thickness of the RF rail 112 and / or the TT electrodes 116, 118 is in the range of approximately 0.1 μm-20 μm. In an exemplary embodiment, the thickness of the first sequence of electrodes 114A and the third sequence of electrodes 114C is greater than the thickness of the RF rail 112 and the second sequence of electrodes 114B, which may be substantially the same thickness.

[0021] In various embodiments, the height of the RF rail 112 and / or the TT electrodes 116, 118 (e.g., in the x-direction) is in the range of about 40 μm to 500 μm. In an exemplary embodiment, the height of the RF rail 112 is approximately equal to the height of the first sequence 114A of electrodes, the second sequence 114B of electrodes, and the third sequence 114C of electrodes. In an exemplary embodiment, the height of the first sequence 114A of electrodes is approximately equal to the height of the third sequence 114C of electrodes. In an exemplary embodiment, the height of the second sequence 114B of electrodes may be less than the height of the first sequence 114A of electrodes and / or the third sequence 114C of electrodes. In an exemplary embodiment, the height of the RF rail 112 is approximately equal.

[0022] In various embodiments, the ion trap 110 is at least partially defined by a plurality of RF rails 112. The RF rails 112 are formed with substantially parallel longitudinal axes 111 (e.g., 111A, 111B) and have substantially coplanar upper surfaces. For example, the RF rails 112 are substantially parallel so that the distance between the RF rails 112 is approximately constant along the length of the RF rails 112 (e.g., the length of the RF rails is along the longitudinal axis 111 of the RF rails). For example, the upper surface of the RF rails 112 may be substantially flush with the upper surface of the ion trap device and / or the package 100. In an exemplary embodiment, the plurality of RF rails 112 include two RF rails 112 (e.g., 112A, 112B). In various embodiments, the ion trap 110 may include a plurality of RF rails 112. For example, the ion trap 110 can be a two-dimensional ion trap including a plurality of numbers (e.g., pairs and / or groups) of RF rails 112, wherein each number (e.g., pairs and / or groups) of RF rails 112 has substantially parallel longitudinal axes 111. In an exemplary embodiment, a first number of RF rails 112 have longitudinal axes 111 that are substantially parallel to each other, a second number of RF rails 112 have longitudinal axes 111 that are substantially parallel to each other, and the longitudinal axes of the first number of RF rails are substantially non-parallel (e.g., transverse) to the longitudinal axes of the second number of RF rails. Figure 1 Two RF rails 112 are shown, although other embodiments may include additional RF rails in various configurations. In various embodiments, the height of the RF rails (e.g., the dimension of the RF rails in the x-direction) and / or the thickness of the RF rails (e.g., the dimension of the RF rails in the z-direction) may vary as appropriate for a particular application. Figure 1 and Figures 3 to 5 As shown, as used herein, the x-axis corresponds to the lateral direction of the ion trap 110 (e.g., perpendicular / orthogonal to the longitudinal direction of the ion trap and in the plane of the surface ion trap 110), the y-axis corresponds to the longitudinal direction of the ion trap 110, and the z-axis corresponds to the vertical direction relative to the upper surface of the ion trap. For example, the longitudinal axes 111 of the plurality of RF rails 112 are substantially parallel to the y-axis.

[0023] like Figure 1 As shown, in various embodiments, a plurality of RF rails 112 may be fabricated above the upper surface of a substrate 130. In various embodiments, other materials (e.g., dielectrics, insulators, shields, etc.) may be formed between the substrate 130 and the components (e.g., RF rails 112, sequence 114 of TT electrodes) fabricated above the upper surface of the substrate 130. Figure 1As shown, each RF rail 112 may be formed with a substantially parallel longitudinal axis 111 (e.g., substantially parallel to the y-axis). As described in some embodiments (e.g., two-dimensional ion trap embodiments), the first set of RF rails 112 may be formed with substantially parallel axes (e.g., axes substantially parallel to the y-axis), and the second set of RF rails 112 may be formed with substantially parallel axes (e.g., axes substantially parallel to the x-axis) and the axes are substantially non-parallel (e.g., transverse) relative to the longitudinal axis of each RF rail in the first set of RF rails 112. In various embodiments, each RF rail 112 is formed with a substantially coplanar upper surface (e.g., defining a plane substantially parallel to the xy plane).

[0024] In various embodiments, two adjacent RF rails 112 may be separated (e.g., insulated) from each other by a longitudinal gap 105. For example, the longitudinal gap (in one or two dimensions) may define a confined channel or confined region of the ion trap 110, wherein one or more ions may be trapped at various locations within the trap. In various embodiments, the longitudinal gap 105 defined thereby may extend substantially parallel to the longitudinal axis 111 of the adjacent RF rails 112. For example, the longitudinal gap 105 may extend substantially parallel to the y-axis. In an exemplary embodiment, the longitudinal gap 105 may be at least partially filled with an insulating material (e.g., a dielectric material). In various embodiments, the dielectric material may be silicon dioxide (e.g., formed by thermal oxidation) and / or other dielectric and / or insulating materials. In various embodiments, the height of the longitudinal gap 105 (e.g., in the x-direction) is approximately between 40 μm and 500 μm. In various embodiments, one or more sequences 114 of TT electrodes (e.g., a second sequence 114B of TT electrodes) may be disposed and / or formed within the longitudinal gap 105.

[0025] In an exemplary embodiment, a lateral gap may exist between adjacent and / or neighboring electrodes 116, 118 of one or more sequences 114 of electrodes. In an exemplary embodiment, the lateral gap may be an empty space and / or at least partially filled with a dielectric material to prevent electrical communication between adjacent and / or neighboring electrodes. In an exemplary embodiment, the lateral gap between adjacent and / or neighboring electrodes may be in the range of approximately 1 μm-10 μm.

[0026] In an exemplary embodiment, there is a longitudinal gap between the sequence of TT electrodes 114 and the adjacent and / or neighboring RF rails 112. In an exemplary embodiment, the longitudinal gap may be at least partially filled with a dielectric material and / or an insulating material to prevent electrical communication between the TT electrodes 116, 118 in the sequence of electrodes 114 and the RF rails 112. In an exemplary embodiment, the longitudinal gap between adjacent and / or neighboring electrodes may be in the range of approximately 1 μm-10 μm.

[0027] In various embodiments, the RF rail 112 may be made of a conductive material (e.g., copper, silver, gold, etc.) or an alloy of two or more conductive materials selected to be suitable for conducting and / or transmitting appropriate signals. In various embodiments, the RF rail 112 may be made of, for example, copper having a cross-sectional thickness (in the z direction) of about 0.1 μm to 10 μm. In various embodiments, the RF rail 112 may be manufactured to have a cross-sectional height (in the x direction) in the range of about 50 μm to about 350 μm. In an exemplary embodiment, the cross-sectional area of ​​the RF rail (e.g., in the xz plane) is determined to be suitable for conducting a current (e.g., from about 0.01 A to about 10.0 A) oscillating at an RF frequency (e.g., from about 3 Hz to 0.3 GHz).

[0028] In various embodiments, the ion trap 110 can be at least partially defined by a plurality of sequences 114 of TT electrodes (e.g., a first sequence 114A of TT electrodes, a second sequence 114B of TT electrodes, a third sequence 114C of TT electrodes). Each sequence 114 of TT electrodes is formed to extend substantially parallel to a substantially parallel longitudinal axis 111 of the RF rail 112. For example, the plurality of sequences 114 of TT electrodes can extend substantially parallel to the y-axis, such as Figure 1 As shown. In various embodiments, the plurality of sequences 114 of TT electrodes include two, three, four, and / or another number of sequences 114 of TT electrodes. In an exemplary embodiment, the ion trap 110 includes a plurality of sequences 114 of TT electrodes. For example, the ion trap 110 may be a two-dimensional ion trap including a plurality of sequences 114 of TT electrodes, each of the plurality of sequences of TT electrodes extending substantially parallel to the substantially parallel longitudinal axes of the corresponding number of RF rails 112. In an exemplary embodiment, the first number of sequences 114 of TT electrodes extend substantially parallel to the substantially parallel longitudinal axes 111 of the first number of RF rails 112, the second number of sequences 114 of TT electrodes extend substantially parallel to the substantially parallel longitudinal axes 111 of the second number of RF rails 112, and the longitudinal axes of the first number of RF rails are substantially non-parallel (e.g., transverse) to the longitudinal axes of the second number of RF rails. In some embodiments, each of the TT electrodes 116, 118 in the plurality of sequences 114 of TT electrodes may be formed with a substantially coplanar upper surface that is substantially coplanar with the upper surface of the RF rail 112.

[0029] In an exemplary embodiment (e.g., Figures 3 to 5), a plurality of (e.g., a pair of) RF rails 112 may be formed between a first sequence 114A of TT electrodes and a third sequence 114C of TT electrodes, wherein a second sequence 114B of TT electrodes extends along a longitudinal channel 105 between the RF rails 112. For example, each sequence 114 of TT electrodes may extend in a direction substantially parallel to the longitudinal axis 111 of the RF rail (e.g., in the y direction). In various embodiments, the upper surface of the sequence 114 of TT electrodes is substantially coplanar with the upper surface of the RF rail 112. In other words, the RF rail 112 and the TT electrodes 116, 118 may be formed to have substantially the same thickness (e.g., in the z direction). In an exemplary embodiment, the thickness (z dimension) and / or height (x dimension) of the first sequence 114A of TT electrodes and the second sequence 114B of TT electrodes may be greater than the RF rail 112 and the third sequence 114C of TT electrodes, and the thickness and / or height of the RF rail and the third sequence of TT electrodes may be substantially the same.

[0030] In various embodiments, multiple sequences 114 of TT electrodes may be fabricated as a plurality of matching TT electrodes. Figures 3 to 5 As shown, the first sequence 114A of TT electrodes may include a first TT electrode (e.g., 116A, 118A), the second sequence 114B of TT electrodes may include a second TT electrode (e.g., 116B, 118B), and the third sequence 114C of TT electrodes may include a third TT electrode (e.g., 116C, 118C). The first TT electrodes 116A, 118A, the second TT electrodes 116B, 118B, and the third TT electrodes 116C, 118C may be a matching set of TT electrodes 140 (e.g., 140W, 140N, as shown in FIG. 1 ). Figure 4). For example, the first TT electrode 116A, the second TT electrode 116B, the third TT electrode 116C or the first TT electrode 118A, the second TT electrode 118B, the third TT electrode 118C may be collinear along a line substantially perpendicular to the substantially parallel longitudinal axes 111 of the corresponding RF rails 112. For example, the first TT electrode 116A, the second TT electrode 116B, the third TT electrode 116C or the first TT electrode 118A, the second TT electrode 118B, the third TT electrode 118C may be collinear along a line substantially parallel to the x-axis. For example, the widths of the first TT electrode 116A, the second TT electrode 116B, the third TT electrode 116C or the first TT electrode 118A, the second TT electrode 118B, the third TT electrode 118C (e.g., in the y-direction) may be the same and may be aligned (e.g., positioned at the same forward edge and / or backward edge) in the longitudinal direction of the ion trap 110 (e.g., in the y-direction). For example, the sequence 114 of TT electrodes includes a plurality of TT electrodes 116, 118 aligned in a longitudinal direction (e.g., y-axis) of the ion trap 110. A matching set of TT electrodes 140 includes a plurality of TT electrodes 116A, 116B, 116C or 118A, 118B, 118C aligned in a longitudinal direction transverse to and / or perpendicular to the ion trap 110. For example, a matching set of TT electrodes 140 includes a plurality of TT electrodes 116, 118 aligned in an x-direction.

[0031] In various embodiments, the ion trap 110 includes a plurality of wide TT electrodes 116 and a plurality of narrow TT electrodes 118. The wide TT electrodes 116 are longer and / or wider than the narrow TT electrodes 118 in a dimension substantially parallel to the longitudinal direction of the ion trap 110 (e.g., substantially parallel to the y-axis). In an exemplary embodiment, each wide TT electrode 116 of the ion trap 110 has approximately a first width W1 in a longitudinal direction substantially parallel to the ion trap 110 (e.g., the y-direction), and each narrow TT electrode 118 of the ion trap 110 has approximately a second width W2 in a longitudinal direction substantially parallel to the ion trap 110, wherein the first width W1 is longer and / or wider than the second width W2. In various embodiments, the first width W1 is approximately at least twice the second width W2. In an exemplary embodiment, the first width W1 is approximately two to approximately six times the second width W2. In an exemplary embodiment, the first width W1 is approximately three to approximately five times the second width W2. In various embodiments, ion trap 110 may include a TT electrode having a width (in a direction substantially parallel to the longitudinal direction of ion trap 110, also referred to as the y-direction) that is longer and / or wider than the first width, between the first width and the second width, or narrower than the second width, depending on the application. In an exemplary embodiment, first width W1 is in the range of approximately 100 μm to 300 μm. In an exemplary embodiment, second width W2 is in the range of approximately 25 μm to 150 μm.

[0032] In various embodiments, the sequence 114 of TT electrodes includes both wide TT electrodes 116 and narrow TT electrodes 118. In various embodiments, the matched set of TT electrodes consists of only wide TT electrodes 116 (e.g., wide matched set 140W of TT electrodes) or only narrow TT electrodes 118 (e.g., narrow matched set 140N of TT electrodes). For example, in an exemplary embodiment, the matched set 140 of TT electrodes does not include both wide TT electrodes 116 and narrow TT electrodes 118.

[0033] In various embodiments, the sequence 114 of TT electrodes is arranged and / or formed into a plurality of zones, such as Figure 3 and Figure 4As shown. For example, these zones may include an action zone, an intermediate zone, a storage zone, etc. Each zone may include two wide matching groups 140W of TT electrodes on the periphery of the zone and at least one narrow matching group 140N of TT electrodes disposed between the two wide TT electrodes. As described above, the wide TT electrode 116 is longer and / or wider than at least one narrow TT electrode 118 in a direction substantially parallel to the substantially parallel longitudinal axis 111 of the RF rail 112 (e.g., in the y direction). In various embodiments, each zone may optimize a specific function and / or set of functions that will occur in the zone. In various embodiments, these functions may include transmitting ions through at least a portion of the zone, stabilizing and / or storing ions in the zone, manipulating ions via a manipulation source (e.g., a laser beam, a microwave field, etc.), interacting, exchanging and / or separating two ions (e.g., dividing two ions in the same potential well into two different and / or separate potential wells), and / or other functions that may achieve the controlled evolution of the quantum state of one or more ions trapped in the ion trap 110. In various embodiments, the ion trap 110 may include one or more repeating patterns of zones.

[0034] In various embodiments, RF signals may be applied to RF rails 112 to generate electric and / or magnetic fields that are used to maintain ions trapped within ion trap 110 in directions transverse to the longitudinal direction (e.g., the x-direction and the z-direction) of ion trap 110. In various embodiments, TT voltages may be applied to TT electrodes 116, 118 to maintain and / or cause ions trapped in ion trap 110 to transport in the longitudinal direction (e.g., in the y-direction) of ion trap 110.

[0035] In various embodiments, the plurality of sequences 114 of TT electrodes may be biased in combination with TT voltages that facilitate a variable combination of electric and / or magnetic fields to trap at least one ion in a potential well above at least one of the upper surfaces of the sequence 114 of TT electrodes and / or the RF rail 112. For example, an electric and / or magnetic field generated at least in part by voltages applied to TT electrodes in the sequence 114 of TT electrodes may trap at least one ion in a potential well above the upper surface of the second sequence 114B of TT electrodes and / or the longitudinal gap 105.

[0036] At least one ion may be trapped at a variable position in ion trap 110 by: the electric and / or magnetic fields being controlled by one or more connected devices (e.g., Figure 230, etc.) via leads 122, 124. For example, depending on the positive or negative charge on the at least one ion, the TT voltage may be raised or lowered for the TT electrodes 116, 118 on either side of the particular TT electrode to promote transport of the at least one ion to the particular TT electrode and / or to form a potential well that resists further transport of the at least one ion.

[0037] Depending on factors such as the charge on at least one ion and / or the shape and / or magnitude of the combined electric and / or magnetic fields, at least one ion may be stabilized at a particular distance (e.g., about 20 μm to about 200 μm) above the upper surface of the ion trap 110 (e.g., the coplanar upper surfaces of the sequence of TT electrodes 114 and the RF rails 112). To further aid in controlling transport between variable positions and / or stabilizing at least one ion trapped at a particular position, in various embodiments, the ion trap 110 may be operated in a cryogenic chamber and / or vacuum chamber capable of cooling the ion trap to a temperature below 124 Kelvin (e.g., below 100 Kelvin, below 50 Kelvin, below 10 Kelvin, below 5 Kelvin, etc.).

[0038] like Figure 1 As shown, the ion trap device 100 may also include a plurality of TT leads, wire bonds, interconnects, etc. (referred to herein as TT leads 122). For example, the TT leads 122 may enable electrical communication between a TT voltage driver and / or a voltage source and a corresponding TT electrode. For example, a TT electrode may be biased with a TT voltage, which is generated and / or provided by a TT voltage driver and / or a voltage source via a corresponding TT lead 122. The ion trap device 100 may also include RF leads, wire bonds, interconnects, etc. (referred to herein as RF leads 124). For example, the RF leads 124 may enable electrical communication between an RF driver and / or a voltage source and an RF rail 112. For example, the RF rail 112 may be biased with a voltage, which alternates at an RF rate and is generated and / or provided by an RF driver and / or a voltage source via the RF leads 124.

[0039] In various embodiments, the ion trap 110 is designed and / or configured to minimize the number of input / outputs (I / Os) (e.g., the number of TT leads 122) and the number of electrodes 116, 118 of the ion trap 110, while allowing all transfer operations required for ion manipulation to be performed in accordance with the intended application (e.g., in an exemplary embodiment, operations for using ions within the ion trap 110 as qubits for a quantum computer). In various embodiments, the design of the electrodes 116, 118 maximizes the harmonics and quarter potential coefficients of the electric and / or magnetic fields generated by biasing the electrodes 116, 118, while satisfying other constraints of the intended application.

[0054] In various embodiments, the storage region 540 includes two wide matching groups 140W of TT electrodes (e.g., matching groups of TT electrodes including wide TT electrodes from each sequence of TT electrodes in a plurality of sequences of TT electrodes). For example, the storage region 540 may include two wide TT electrodes 116 from each sequence of TT electrodes (e.g., matching groups of wide TT electrodes 116A, 116B, 116C). Between the two wide matching groups 140W of TT electrodes are at least two narrow matching groups 140N of TT electrodes (e.g., matching groups of TT electrodes including narrow TT electrodes from each sequence 114 of TT electrodes in a plurality of sequences 114A, 114B, 114C of TT electrodes).

[0055] In various embodiments, the loading region 550 is configured to receive ions from an ion source so that the ions can be loaded into the ion trap 110. For example, the loading region 550 may include a loading aperture 555. The loading aperture is a through hole extending through the ion trap 110 and through the substrate 130 to allow the ion source to be disposed under the ion trap device and / or package 100 so that atoms from the ion source can travel through the loading aperture 555 into the loading region 550. Once the atoms enter the loading region 550 through the loading aperture 555, the atoms can be ionized and the resulting ions can be trapped due to the electric and / or magnetic fields and / or the corresponding potentials generated by the plurality of sequences 114 of TT electrodes and the plurality of RF rails 112. In an exemplary embodiment, atoms can enter the loading region 550 via the loading aperture 555 and interact with a manipulation source (e.g., a laser beam) that ionizes the atoms so that the resulting atoms are trapped within the ion trap 110. In various embodiments, the loading region 550 can be configured to receive ions (or atoms) through the loading aperture 555, stabilize the ions (e.g., ionized atoms) within the loading region 550, enable manipulation of the ions (e.g., to initialize the ions and / or ensure that the ions are in a known initial quantum state) via one or more manipulation sources, etc. The loading region 550 can also be configured to facilitate transport of ions out of the loading region 550 and into the immediately adjacent intermediate region 520.

In an exemplary embodiment, the width of the wide TT electrode 116 of the intermediate region 520 (e.g., in a dimension substantially parallel to the y-axis) is different from the width of the wide TT electrode 116 of the active region 530 and / or the storage region 540.
