SPICE Workshop on Quantum materials and quantum information science May 19th - 21st, 2026
Frank Schlawin
In this talk, I will discuss how the development of nonclassical states of light in quantum information science has created important opportunities for spectroscopy, imaging and optical control in condensed matter. Bright squeezed vacuum states, which contain a macroscopic number of photons, have become available in recent years. They combine strong correlations with femtosecond temporal resolution and large peak intensities. Strong spatiotemporal quantum correlations and their detection may affect signal strength and the signal-to-noise ratio, and may enable the targeted excitation of entangled states of matter.
In the first part of my talk, I will demonstrate how the machinery of quantum metrology can be used to systematically develop quantum-enhanced spectroscopy and imaging protocols, focusing in particular on Raman scattering. Then, I will turn to optical control with quantum light and cavity QED. I will present a formalism to describe quantum systems strongly driven by such quantum states of light. I will then discuss potential applications in Floquet engineering and opportunities for quantum-enhanced or quantum-enabled optical control of materials.
