We introduce a Xilinx RF System-on-Chip (RFSoC)-based qubit controller (called the Quantum Instrumentation Control Kit, or QICK for short), which supports the direct synthesis of control pulses with carrier frequencies of up to 6 GHz. The QICK can control multiple qubits or other quantum devices. The QICK consists of a digital board hosting an RFSoC field-programmable gate array, custom firmware, and software and an optional companion custom-designed analog front-end board. We characterize the analog performance of the system as well as its digital latency, important for quantum error correction and feedback protocols. We benchmark the controller by performing standard characterizations of a transmon qubit. We achieve an average gate fidelity of F=99.93%. All of the schematics, firmware, and software are open-source.
我们推出了一种基于赛灵思射频片上系统（RFSoC）的量子比特控制器（简称为量子仪器控制套件，即QICK），它支持直接合成载波频率高达6GHz的控制脉冲。QICK可以控制多个量子比特或其他量子设备。QICK由一块数字板组成，该数字板搭载了一个RFSoC现场可编程门阵列、定制固件和软件，以及一块可选的配套定制设计模拟前端板。我们对该系统的模拟性能及其数字延迟进行了表征，这对于量子纠错和反馈协议很重要。我们通过对一个传输子量子比特进行标准表征来对该控制器进行基准测试。我们实现了平均门保真度F = 99.93%。所有的原理图、固件和软件都是开源的。
