AI 中文摘要
在不同量子场之间建立有效的空间关联对于多物理量量子传感至关重要。我们在此提出一种基于混合纠缠的关联成像方法，该纠缠产生于微波光子与通过超导量子电路生成的微波表面声波声子之间。在匹配的微波频率下，光子与声子之间五个数量级的波长差异导致了一种独特的量子纠缠资源，该资源允许用于探测物体的最优场与用于读出的场不同。这一资源实现了两种具有巨大空间缩放能力的成像模式：将宏观物体轮廓缩小10^{-8}-10^{-6}倍到微观声子芯片上，以及相反地，将微观物体轮廓放大10^{4}-10^{6}倍到宏观光子读出设备中。通过将自由空间的长波长微波与芯片上的短波长表面声波对接，我们的关联成像方法为跨尺度量子传感提供了一个通用框架。
英文摘要
Establishing effective spatial correlations between distinct quantum fields is essential for multi-physics quantum sensing.~We here propose a correlation imaging approach based on the hybrid entanglement between microwave photons and microwave surface acoustic wave phonons generated via a superconducting quantum circuit.~At matched microwave frequencies, the five order-of-magnitude wavelength disparity between photons and phonons leads to a unique quantum entanglement resource, which allows the optimal field for probing an object to be distinct from that used for readout.~This resource enables two imaging modalities with giant spatial scaling: a $10^{-8}-10^{-6}$-fold demagnification of macroscopic object profiles onto microscopic phononic chips, and conversely, a $10^{4}-10^{6}$-fold magnification of microscopic object profiles into macroscopic photonic readout devices. By interfacing free-space long-wavelength microwaves with on-chip short-wavelength surface acoustic waves, our correlation imaging approach provides a general framework for cross-scale quantum sensing.
