Wireless Controls and Readouts for Qubit Upscaling (WiQC)

量子计算机（QC）系统有可能改变计算技术，解决传统基于二进制逻辑的计算机无法解决的未解决的科学问题。具有127个量子位的最先进的商用QC最近在IBM（2021年11月）进行了演示。然而，要揭示量子计算机的真正潜力，需要几百或几千个量子比特。目前的QC架构和技术很难实现这一点，主要是由于不可扩展硬件的限制，例如稀释冰箱的大小和用于量子位控制和读出的大量电缆。在这个项目中，我们将研究一种高风险但有潜在回报的技术，以克服扩大现有量子模拟器和计算机尺寸的紧迫技术挑战。我们将利用成熟的无线技术，为下一代具有无线cpu的qc消除笨重和昂贵的有线系统。该技术可以以非常紧凑的方式容纳数百或数千个量子位。这可能会导致现有QC系统架构的范式转变，并创造几个新的研究领域。

Quantum computer (QC) systems have the potential to transform computing technology and tackle the unsolved scientific issues that conventional binary logic-based computers are incapable of. The state-of-the-art commercial QC with 127 qubits was recently demonstrated at IBM (Nov 2021). However, to reveal the true potential of the QCs, several-hundred or thousand qubits are required. This is hardly achievable with current QC architectures and technologies, mainly due to the constraint of unscalable hardware such as the size of dilution refrigerators and numerous cables for qubit controls and readouts. In this project, we will investigate a highly risky but potentially rewarding technique for overcoming the urgent technological challenge of scaling up the size of existing quantum simulators and computers. We will take advantage of the matured wireless technology and remove the bulky and costly wired systems for future generation of QCs with wireless CPUs. The proposed technique could potentially host hundreds or thousands of qubits in a very compact way. This could potentially lead to paradigm shifts in existing architectures of QC systems and create several new fields of research.
