Classical light sources, like Lasers, have a fundamental limit on how small of a signal they can measure (the Standard Quantum Limit). Quantum light sources can measure signals below this limit, and those with entangled photons have been theorized to produce more efficient rates of Two Photon Absorption. This has led to considerable interest in studying whether quantum light sources can improve biological imaging relative to classical light sources. I aim to investigate this theorized “quantum advantage” using a particular kind of quantum light (Intensity-Difference Squeezed Light) for spectroscopic and fluorescence-lifetime measurements on molecules relevant to biological imaging.
