Monolithic Integration of Quantum Resonant Tunneling Gate on a 22nm FD-SOI CMOS Process
摘要：
量子计算技术的激增推动了建造实用量子计算机的竞赛。创新的范围很广，涵盖了这项技术的许多方面，例如量子位、控制和检测机制、低温电子学和系统集成。这些新兴技术中的一些已经准备好成功地将低温电子学与量子比特所在的量子结构进行单片集成。在这项工作中，我们提出了一个完全集成的量子处理器单元，其中量子核心与控制和检测电路位于同一芯片上，采用GlobalFoundries的商业22 nm FD-SOI工艺。在这项工作中描述的系统包括一个二维（2D）240量子位阵列集成8个探测器和32个注射器在3 K和两级Gifford-McMahon制冷机内运行。每个检测器和进样器的功耗分别为1 mW和0.27mW。控制序列被编程到片上模式发生器中，该发生器充当Quantum处理器单元中所有硬件的命令和控制块。使用上述装置，我们对2D量子比特阵列中的两个量子比特进行了量子共振隧穿实验。通过支持实验室测量，我们证明了所提出的架构在将现有量子核扩展到数千个量子位方面的可行性。
英文摘要：
The proliferation of quantum computing technologies has fueled the race to build a practical quantum computer. The spectrum of the innovation is wide and encompasses many aspects of this technology, such as the qubit, control and detection mechanism, cryogenic electronics, and system integration. A few of those emerging technologies are poised for successful monolithic integration of cryogenic electronics with the quantum structure where the qubits reside. In this work, we present a fully integrated Quantum Processor Unit in which the quantum core is co-located with control and detection circuits on the same die in a commercial 22-nm FD-SOI process from GlobalFoundries. The system described in this work comprises a two dimensional (2D) 240 qubits array integrated with 8 detectors and 32 injectors operating at 3K and inside a two-stage Gifford-McMahon cryo-cooler. The power consumption of each detector and injector is 1mW and 0.27mW, respectively. The control sequence is programmed into an on-chip pattern generator that acts as a command and control block for all hardware in the Quantum Processor Unit. Using the aforementioned apparatus, we performed a quantum resonant tunneling experiment on two qubits inside the 2D qubit array. With supporting lab measurements, we demonstrate the feasibility of the proposed architecture in scaling-up the existing quantum core to thousands of qubits.
