摘要

扩展硅基量子点中的自旋量子比特是实现大规模半导体量子计算的关键挑战之一。为了满足连接性要求并降低光刻复杂性,利用量子比特阵列结构和电路量子电动力学(cQED)架构有望成为一种可行的扩展方案。与超导谐振器耦合的三量子点(TQD)被视为演示这种扩展方案的基本单元。在本文中,我们研究了一个由硅 TQD 和高阻抗 TiN 共面波导 (CPW) 谐振器组成的系统。TQD 可以通过右双量子点 (RDQD) 与谐振器耦合,达到强耦合机制,电荷光子耦合强度为 g0/(2π) = 175 MHz。此外,我们还通过对稳定性图、四重点(QPs)和量子蜂窝自动机(QCA)过程的表征,说明了 TQD 的高可调性。我们的研究成果有助于促进硅基量子比特集成的探索。

Coupling and characterization of a Si/SiGe triple quantum dot array with a microwave resonator
Scaling up spin qubits in silicon-based quantum dots is one of the pivotal challenges in achieving large-scale semiconductor quantum computation. To satisfy the connectivity requirements and reduce the lithographic complexity, utilizing the qubit array structure and the circuit quantum electrodynamics (cQED) architecture together is expected to be a feasible scaling scheme. A triple-quantum dot (TQD) coupled with a superconducting resonator is regarded as a basic cell to demonstrate this extension scheme. In this article, we investigate a system consisting of a silicon TQD and a high-impedance TiN coplanar waveguide (CPW) resonator. The TQD can couple to the resonator via the right double-quantum dot (RDQD), which reaches the strong coupling regime with a charge–photon coupling strength of g0/(2π) = 175 MHz. Moreover, we illustrate the high tunability of the TQD through the characterization of stability diagrams, quadruple points (QPs), and the quantum cellular automata (QCA) process. Our results contribute to fostering the exploration of silicon-based qubit integration.
