Project description
Quantum technology-based detection of phonons with unprecedented sensitivity
Much as photons are quanta or packets of light, phonons are quanta of vibrational(mechanical) energy. These collective motions or vibrations of atoms or molecules correspond to sound when at low frequencies and to heat at higher frequencies. Phonons are particularly relevant to the propagation of heat and sound in crystals. Characterising the phononic properties of materials is essential to understanding condensed matter physics and developing next-generation technologies. A quantum lock-in amplifier can detect subtle oscillations in the quantum state phase, which can be affected by phonons, enabling phonon detection. With the support of the Marie Skłodowska-Curie Actions programme, the Q-LAMP project aims to develop an innovative quantum lock-in amplifier phonon detector with unparalleled resolution and sensitivity.
Objective
The precise measurement of phononic properties of materials is crucial for the emerging physics and next-generation technologies. With the ever-growing study of phononic many-body physics, the need for precise phonon measurement has become increasingly important. Quantum lock-in measurement techniques offer a promising avenue for future phonon detection, boasting significant advantages such as ultra-high resolution, heightened sensitivity, and the capability for concurrent measurement of amplitude, frequency, and phase.
In this project, I propose innovative quantum lock-in amplifier phonon detector (Q-LAMP) for phonon detection for the first time and plan to experimentally demonstrate their effectiveness in simultaneously measuring phonon phase, frequency, and amplitude. I plan to use Q-LAMP to measure topological localized states in phononic crystals and can also be employed for detecting weak microwaves. The quantum lock-in amplifier developed in this project will pushing both phononics physics and wireless communication to new stage.
This interdisciplinary training scheme is designed to enhance Ruihuan's expertise in quantum optics, fortifying his skills and helping him establish a research career in Europe. It covers component design and implementation, theoretical analysis, mathematical modelling and applications. To assist Ruihuan in attaining professional maturity and broadening his exposure to academic and industrial collaborations, he will receive training on intellectual property management, funding and proposal writing, commercialization, supervision and teaching. Secondment in academic host, with Prof. Martijn Wubs (DTU, Denmark) is arranged to pursue scientific objectives, enriching Ruihuan's learning experience, expanding his network in Europe and maximizing the impact of research and training on the EU society and industry.
