The goniometer mount system includes a mounting bracket comprising a base plate and a back plate having a plurality of slots radially disposed about a center of the back plate. The goniometer mount system includes a rotary mounting plate that is rotatably coupled to the mounting bracket and configured to rotate about an axis extending through the center of the back plate that is circumscribed by the plurality of slots. ## Claims ### Claim 1 A goniometer mount system for use with a quantum information processing (QIP) system, the goniometer mount system comprising: a mounting bracket comprising a base plate and a back plate having a plurality of slots radially disposed about a center of the back plate, wherein the plurality of slots extend through the back plate; and a rotary mounting plate that is rotatably coupled to the mounting bracket and configured to rotate about an axis extending through the center of the back plate that is circumscribed by the plurality of slots. ### Claim 2 (depends on 1) The goniometer mount system of claim 1, further comprising an acousto-optical deflector including a crystal configured to deflect an incoming beam, wherein a center of the crystal is aligned with the axis. ### Claim 3 (depends on 1) The goniometer mount system of claim 1, further comprising a bearing positioned between the rotary mounting plate and the back plate. ### Claim 4 (depends on 1) The goniometer mount system of claim 1, wherein the axis extending through the center of the back plate is a first axis, and wherein the system further comprises an actuator rotatably coupled to the back plate and seated against a surface of the rotary mounting plate, wherein the actuator is rotatable about a second axis in an actuator first direction to rotate the mounting plate about the first axis in a mounting plate first direction and the actuator is rotatable about the second axis in an actuator second direction to rotate the mounting plate about the first axis in a mounting plate second direction. ### Claim 5 (depends on 4) The goniometer mount system of claim 4, wherein the second axis and the first axis are orthogonal. ### Claim 6 (depends on 4) The goniometer mount system of claim 4, further comprising a spring that includes a first end coupled to the back plate and a second end coupled to the rotary mounting plate, and wherein the spring is configured to maintain engagement between the actuator and the surface of the rotary mounting plate. ### Claim 7 (depends on 1) The goniometer mount system of claim 1, further comprising one or more fasteners movable from a first position in which the rotary mounting plate is configured to rotate relative to the back plate and a second position in which the rotary mounting plate is prevented from rotating relative to the back plate. ### Claim 8 (depends on 7) The goniometer mount system of claim 7, further comprising one or more bearings that are coupled to each of the one or more fasteners, respectively, the one or more bearings being configured to prevent movement of the rotary mounting plate as the one or more fasteners are moved from the first position to the second position. ### Claim 9 (depends on 8) The goniometer mount system of claim 8, wherein the one or more fasteners are configured to be positioned in the plurality of slots, and wherein the plurality of slots define a path of the rotation of the rotary mounting plate. ### Claim 10 (depends on 8) The goniometer mount system of claim 8, wherein the rotary mounting plate is continuously positioned along a range of angles defined by the plurality of slots. ### Claim 11 (depends on 9) The goniometer mount system of claim 9, wherein the rotary mounting plate is configured to rotate between −7° to 7° about a position in which the one or more fasteners are substantially centered in the one or more slots. ### Claim 12 (depends on 8) The goniometer mount system of claim 8, further comprising a spring washer that is engaged with each of the one or more fasteners, and wherein the spring washer is configured to prevent the rotary mounting plate from moving away from the back plate while the one or more fasteners are in the first position.
