Summary
Light-matter coupling is a key element of many Quantum Information (QI) devices that enable quantum enhanced sensing and information processing.
This coupling can be enhanced using optical tools including high finesse cavities, allowing exquisite control of quantum degrees of freedom of individual atoms in the domain of cavity quantum electrodynamics. Applying these precision optical tools to condensed matter systems presents an opportunity to unlock a wide array of optically-enhanced materials for QI applications, both in the context of externally driven systems, and systems where the cavity-vacuum directly influences materials properties.
Of particular interest is the regime of strong light-matter coupling where hybrid systems emerge that inherit useful properties from both their light and matter constituents.
QUAMELEON seeks to push the boundaries of optical control of solid-state materials, extending established Floquet engineering techniques to regimes where material properties can meaningfully be changed by electromagnetic fields at the few-photon level or by cavity-enhanced vacuum modes.
Examples include new phases of matter and out-of-equilibrium effects. Of particular interest are systems where engineered light-matter coupling can be used to enhance or quantify the inter-particle interactions and correlations in a material.
QUAMELEON seeks to discover new physics insights that can be exploited for QI devices such as quantum enhanced sensors, light sources or detectors, transducers, and quantum emulators.
This ARC Opportunity is soliciting ideas to explore the following question: How can engineered light-matter coupling be used to control or enhance quantum materials by harnessing vacuum effects or few-photon external drives?
