Quantum Microscopy in the mid-Infrared
Quantum imaging overcomes the limitations of conventional optics and offers advantages such as higher resolution and lower phototoxicity. The focus is on two-colour processes with SPDC photon pairs for better detection in the infrared range, for example for biomedical applications.
Quantum imaging protocols have been emerging in the last decades as powerful tools to move
beyond the limitations imposed by classical optics on existing imaging systems, and unlock
quantum-enhanced capabilities, in terms of resolution, enhanced signal-to-noise ratio, lowlight illumination-enabled reduced phototoxicity, and the possibility to exploit quantum
frequency correlations to perform imaging in wavelength ranges where detection technology
is underdeveloped using standard CMOS silicon camera technology. Focusing on the last of
the above-mentioned four directions to pursue a “quantum advantage” in imaging systems, we
present our latest progress in “two-color” quantum imaging schemes, based on frequency
correlations of photon-pairs generated through Spontaneous Parametric Down-conversion
(SPDC), to access the mid-infrared spectral region with enhanced detection efficiency for biomedical applications. We further discuss technical implementation bottlenecks through
Quantum Imaging with Undetected Light (QIUL) and discuss feasibility and scalability towards
market uptake.
