Abstract: Aspects of the present disclosure describe controlling coherent crosstalk errors in multi-channel acousto-optic modulators (AOMs). A method, an AOM system, and a quantum information processing (QIP) system are described in which a separate radio-frequency (RF) signal is generated and applied to each of multiple channels of a multi-channel AOM using an arbitrary waveform generator (AWG) to turn on each of those channels, where each channel that is turned on interacts with one or more of the remaining channels that are not turned on to cause a combined crosstalk effect on those remaining channels. Each channel has a single respective AWG. Moreover, a correcting RF signal is generated and applied to the one or more of the remaining channels using a respective AWG to produce an acoustic wave that corrects for the combined crosstalk effect such that the one or more of the remaining channels are not unintentionally turned on.

Abstract: Technologies are described herein to implement an optimizer that receives portions of a quantum circuit; identifies, from within the received portions of the quantum circuit, a pattern of quantum gates to perform a quantum function; searches a library for a replacement pattern of quantum gates, which is also to perform the quantum function, for the identified pattern of quantum gates; determines that a quantum cost of the replacement pattern of quantum gates is lower than a quantum cost of the identified pattern of quantum gates; and replaces the identified pattern of quantum gates with the replacement pattern of quantum gates.

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 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.

Abstract: Systems and techniques are provided for pulse generation. A classical computing device may receive a program source code including quantum operations. The program source code may be compiled into a compiled program including the one or more quantum operations. Pulse shapes that a pulse shape library indicates corresponds to each of the quantum operations may be determined. Pulse instructions based on the one or more pulse shapes that the pulse shape library indicates corresponds to each of the quantum operations may be generated. Binary format instructions may be generated based on the pulse instructions. The binary format instruction may encode the pulse instructions in binary packets using a binary code of a field programmable gate array (FPGA) of a quantum computing device.

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 correction of light-shift effects in trapped-ion quantum gates. Techniques are described for light-shift correction of single qubit gates when the gates are implemented using counter-propagating Raman laser beams and when the gates are implemented using co-propagating Raman laser beams. Moreover, techniques are also described for light-shift correction of two-qubit gates.

Abstract: A system and method is provided for optimizing an input quantum circuit. An exemplary method includes searching a library of templates to find, by compiling abstract gate operations into a set of hardware-specific operations that manipulate qubit states, a template of quantum circuit gates that performs a predetermined function and that matches a set of quantum circuit gates in the input quantum circuit that performs the predetermined function; and replacing the set of quantum circuit gates in the input quantum circuit with the template of quantum circuit gates when the template of quantum circuit gates has a lower quantum cost than the set of quantum circuit gates based on estimated execution times. Moreover, the method is executed in a pipeline in combination with at least quantum circuit compilation.
