摘要： The disclosure describes various aspects of different for automated testing of optical assemblies. A system is described that includes an arm (e.g., a motorized arm) configured to be positioned over an optical assembly having a base plate with multiple optical elements that form one or more optical beam paths. The system also includes at least one optical tool that is configured to be removably attached to the arm and has a measurement instrument to perform a specified test on at least one of the optical beam paths. The arm is configured to adjust its position over the optical assembly to move the optical tool to the correct place to perform the specified test. The system may also include an optical tool changer configured to hold the optical tool in a tool holder when not attached to the arm and to hold additional optical tools in respective tool holders.

摘要： 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 techniques for removing or correcting for translation errors between a programmed strength and an applied strength of quantum gates. A method is described that includes determining, for each quantum gate in a quantum operation, a non-linearity between an applied strength of a laser beam used for the respective quantum gate and a programmed strength intended to be applied by the laser beam for the respective quantum gate. The method further includes linearizing the non-linearity for each quantum gate and storing linearization information in memory. Moreover, the method includes applying the linearization information to correct for the non-linearity when implementing each quantum gate as part of the quantum operation. A system is also described that is configured to implement the method described above.

摘要： Aspects of the present disclosure describe a method including predicting a first set of ansatz terms and a first plurality of amplitudes associated with the first set of ansatz terms; minimizing energy of the system based on the first set of ansatz terms and the first plurality of amplitudes; computing perturbative corrections using one or more ansatz wavefunctions; determining whether energy of the system converges; and predicting, in response to determining that the energy of the system does not converge, a second set of ansatz terms and a second plurality of amplitudes associated with the second set of ansatz terms.

摘要： 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.

摘要： Aspects of the present disclosure relate generally to parallel sideband cooling of multiple trapped-ion motional modes with deflectors (e.g., acousto-optic deflectors or AODs) in quantum information processing (QIP) systems. A method and a system are described in which for an ion chain a first group of ions (e.g., middle section of the ion chain) and a second group of ions (e.g., outer sections of the ion chain) are identified. The method and system include performing sideband cooling by applying, to the first group of ions, a first pair of optical beams using a first pair of AODs, and applying, to the second group of ions, a second pair of optical beams using a second pair of AODs. For each AOD, an acousto-optic modulator (AOM) may be placed upstream to provide frequency modulation for matching frequency differences for correct detuning as part of the sideband cooling operation.

摘要： 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 use of deflectors in trapped ion QIP systems for individually addressing long ion chains. Methods are described for using acousto-optic deflectors (AODs) in optical Raman transitions to implement single-qubit gates and two-qubit gates. A QIP system is also described that is configured to use AODs in optical Raman transitions to implement single-qubit gates and two-qubit gates.

摘要： The disclosure describes various aspects of a system with scalable and programmable coherent waveform generators. A network and digital-to-analog conversion (DAC) cards used by the network are described where each DAC card has a clock divider/replicator device with an input SYNC pin, a digital logic component, and one or more DAC components, and each output of the DAC components is used to control optical beams for a separate qubit of a quantum information processing (QIP) system. The network also includes a first distribution network to provide a clock signal to the clock divider/replicator device in the DAC cards, and a second distribution network to provide a start signal to the DAC cards, where the start signal is used by the digital logic component in the DAC card to assert the input SYNC pin when the start signal is asserted unless it is masked by the digital logic component.

摘要： 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.

摘要： Aspects of the present disclosure may include a method and/or a system for identifying an ion chain having a plurality of trapped ions, selecting at least two non-consecutive trapped ions in the ion chain for implementing a qubit, applying at least a first Raman beam to shuttle at least one neighbor ion of the at least two non-consecutive trapped ions from a ground state to a metastable state, and applying at least a second Raman beam to one or more of the at least two non-consecutive trapped ions, after shuttling the at least one neighbor ion to the metastable state, to transition from a first manifold to a second manifold.
