Quantum Microscopy

Modern imaging techniques, grounded in classical optics principles, have enabled us to explore microscopic structures with remarkable precision and observe objects millions of light-years away. Despite their success, these classical systems face fundamental limitations, prompting the emergence of quantum-based imaging technologies that offer unprecedented capabilities.

At QC2, we are pioneering quantum imaging experiments that harness the principles of quantum mechanics to transcend the boundaries of classical imaging. Unlike traditional methods relying on lasers or LEDs as light sources, our approach uses spatially and temporally entangled photon pairs. These entangled pairs allow information carried by one photon to be inferred from its twin, exploiting non-classical correlations to achieve breakthroughs in imaging performance.

One of the key advantages of our quantum imaging system is enhanced spatial resolution. By illuminating samples with entangled photons, we effectively achieve imaging with half the wavelength of classical light, enabling super-resolution imaging beyond the diffraction limit. Additionally, since entangled photons are generated through weak nonlinear processes, they induce minimal damage to delicate samples—a critical benefit for biological and material sciences.

Our quantum imaging technique extends its benefits to include high sensitivity, enhanced depth resolution, reduced shot noise, and improved signal-to-noise ratios. It also facilitates advanced applications such as ghost imaging, guidestar-free aberration correction, and time-gated imaging techniques like optical coherence tomography (OCT). These features open the door to a wide range of applications, from biomedical diagnostics to precision materials analysis.

By combining state-of-the-art experimental setups with the transformative potential of quantum mechanics, we aim to redefine imaging standards. Our work positions quantum imaging as a vital tool for the next generation of scientific exploration, addressing challenges that classical systems cannot overcome.
