Abstract: Aspects of the present disclosure relate generally to systems and methods for using a goniometer mount system for use with a quantum information processing (QIP) system. 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.

Abstract: Aspects of the present disclosure relate generally to systems and methods for use in the implementation and/or operation of quantum information processing (QIP) systems, and more particularly, to the implementation and use of a quantum information processing (QIP) system including one or more vertical nanopositioners configured to reposition one or more components coupled to the nanopositioner and weighing between about 1 kilogram (kg) and about 5 kgs. The one or more vertical nanopositioners may be positioned in the cryogenic environment.

Abstract: Aspects of the present disclosure relate generally to systems and methods for use in the implementation and/or operation of quantum information processing (QIP) systems, and more particularly, to a double individual-addressing multi-beam Raman system for use in QIP systems. A technique is described in which a first muti-channel modulator (MCM), a first telecentric zoom lens, and a first interleaver that form a first optical path of the Raman system that receives a first array of beams and adjusts the first array of beams to individually address atomic-based qubits in a chain from a first direction. Moreover, a second MCM, a second telecentric zoom lens, and a second interleaver form a second optical path of the Raman system that receives a second array of beams and adjusts the second arrays of beams to individually address the atomic-based qubits in the chain from a second direction different from the first direction.

Abstract: A measurement device including a fastener for use in attaching a first member to a second member, in which the fastener has an aperture extending through a length of the fastener, and a first optical fiber located within the aperture, in which the first optical fiber includes at least one fiber Bragg grating sensor. At least a portion of the first optical fiber can be secured within the aperture. A first end of the first optical fiber can be connected to an associated first optical connector and a second end of the first optical fiber can be connected to an associated second optical connector.

Abstract: A fiber optic cable winding tool having a disk-shaped base and a pair of semi-circular spools slidably mounted on the base. The spools are radially adjustable toward and from the central axis of the base by providing the spools on rails connected to and radially extending away from the central axis of the base. Each spool has a fiber optic cable contacting surface with a radius of curvature exceeding a minimum bend radius of the fiber optic cable. A pair of linkage arms connect to each spool and further connect to a slide block spaced from the spools. One of the spools is capable of being retained against the base once the desired diameter of the winding is located. The retained spool, in conjunction with the linkage arms and slide block, prevent the other spool from sliding relative to the base. This way the diameter of the spools can be set and the fiber optic cable may be wound thereon.

Abstract: A controller sets polishing parameters and automatically supplies materials needed for polishing to a polishing unit in accordance with a type of connector to be polished. The controller may also control the duration and pressure applied during polishing. Washing and any repeating of polishing may also be automated. Once polishing is complete, the connector may be inspected to determine if it has been satisfactorily polished. If not, the polishing parameters may be altered and the connector is repolished and reinspected.

Abstract: An optical fiber alignment apparatus for leveling respective distal ends of a plurality of optical fibers prior to commencing a polishing process. The apparatus includes an aligning device having a plurality of receptacles for securing the corresponding plurality of optical fibers such that distal ends of the optical fibers extend below the base of the aligning device. A sensor array contacts the distal ends of the optical fibers and generates sensor alignment signals indicating the position of the fiber distal ends extending below the aligning device relative to a horizontal reference plane. A monitor receives and displays digital signals corresponding to the sensor alignments signals. Those optical fibers that are not aligned are then adjusted to until all the fibers are aligned and leveled with respect to the horizontal reference plane as viewed on the monitor.

Abstract: A polishing apparatus for polishing optical fibers includes a polishing pad and a polishing arm arranged above the polishing pad and which is selectively brought into contact with the polishing pad. A leveling device is magnetically attached to a lower end of the polishing arm. The leveling device has a plurality of optical fiber ends extending downwardly from a lower surface thereof to contact the polishing pad. The polishing arm also contains a pressure transducer for measuring a pressure applied by the polishing arm when the polishing arm contacts the polishing pad. The magnetic attachment between the polishing arm and leveling device may be carried out using a permanent magnet or electromagnet.

Abstract: A metrology frame for holding, transporting and aligning optical fibers while interconnecting optical fibers. The metrology frame includes an elongated rail and a pair of brackets slidably attached to the rail. The brackets are interconnected to a drive mechanism for moving the brackets along the rail. Attached to the brackets are aligning devices that orient and secure the optical fibers that are led from a fiber cassette. The metrology frame allows the optical fibers to be transferred through a series of optical fiber interconnection steps without having to re-secure or re-orient the fibers between the steps.

Abstract: A calibration apparatus and method for a polishing machine includes a ferrule surrounding a polishing pad and a plurality of sensors attached to the ferrule. Each of the sensors is directed at a location where optical fibers extending downwardly from a leveling device contact the polishing pad. The sensors are infrared sensors that detect a heat signature generated by friction at the contact point between the optical fibers and the polishing pad as the polishing pad spins and revolves relative to the leveling device. The heat signature that is generated corresponds to the pressure existing between the optical fibers and the polishing pad.
