This research advances quantum sensing capabilities by engineering the spectral response of surface acoustic wave resonators through dual electromagnetic and acoustic Fano interference. The technique achieves a six-fold sensitivity enhancement across a broad temperature range, offering new tools for probing condensed-matter systems and manipulating collective states in quantum technologies. By controlling device response rather than just optimizing design, this work expands the utility of SAWs for detecting minute environmental changes relevant to future quantum applications.

Michigan Team Shapes Resonator Spectra with Dual Interference

Electromagnetic and acoustic Fano Interference in Surface Acoustic Wave Resonators Until now, detecting minute environmental changes with surface acoustic waves relied on optimising device design or electrical signals. This work introduces a method that instead engineers the very *response* of these devices via tailored interference effects, enhancing detectability of frequency shifts. Such control opens new avenues for more sensitive sensors across fields ranging from materials science to quantum technologies.

P. K. Rath from the Indian Association for the Cultivation of Science and colleagues report a new method for shaping the spectral response of gigahertz-frequency surface acoustic wave resonators by simultaneously introducing both electromagnetic and acoustic Fano interference. Systematic modification of resonator acoustic reflectivity allowed isolation and analysis of each interference mechanism independently. The broad operating temperature range, from ambient to cryogenic temperatures, highlights potential applications in both classical and quantum…
