Smarter operating system for quantum dot qubits

量子点量子比特代表了一种很有前途的量子计算方法。它们需要各种各样的控制信号，即使只有几个量子位，也需要复杂的仪器。具有同步、可编程任意波形发生器和数字化仪的可扩展平台是进行下一代多量子位实验的合适解决方案。此外，现场可编程阵列的实时处理能力为量子点的校准和测量提供了新的可能性。拟议的研究将舍布鲁克大学量子研究所的量子点专业知识与是德科技的专业电子技术相结合，以开发专用的可扩展量子点量子位仪器。此次Engage合作的可交付成果是(i)一份报告，提供了弥合是德科技仪器和Institut quantique量子点之间技术差距的解决方案，以及（ii）一个内置在是德科技量子计算机研究工具包中的多通道锁定放大器。与是德科技研发人员的互动将为学生提供独特的机会，让他们了解世界上最大的多技术公司之一。拟议的研究是是德科技将自己建立为量子点量子比特的仪器标准的一个机会，因为该技术的复杂性在不断扩大。

Quantum dot qubits represent a promising approach for quantum computing. They require a variety of controlsignals, demanding complex instrumentation even for few qubits. A scalable platform with synchronized,programmable arbitrary waveform generators and digitizers is an appropriate solution to carry the nextgeneration of multi-qubit experiments. Moreover, real time processing capability of Field Programmable Arrayopens up new calibration and measurement possibilities in quantum dots. The proposed research merges thequantum dot expertise of Institut Quantique of Université de Sherbrooke with the specialized electronicsknowhow of Keysight Technology to develop dedicated and scalable quantum dot qubits instrumentation. Thedeliverables of this Engage collaboration are (i) a report providing solutions for bridging the technological gapsbetween Keysight instrumentation and Institut quantique's quantum dots, and (ii) a multi-channel lock-inamplifier built into Keysight's Quantum Computer Research Toolkit. Interaction with Keysight R&D staff willprovide unique opportunities for students to gain exposure to one of the largest multi-technological firms in theworld. The proposed research is an opportunity for Keysight to establish itself as the instrumentation standardfor quantum dots qubits, as the technology scales up in complexity.
