Quantum Multi-Wavelength Holography creates high-fidelity 3D images of microscopic objects using quantum entangled photons

"illuminate target using IR, imaging using visible light quantum-entangled with the IR probe, capturing both intensity/ phase, enabling holographic images capturing object's contour depths, for accurate 3D images using indirect photons... IR for safe, skin-penetrating biological imaging, but doing so conventionally requires expensive IR detectors for imaging... instead, inexpensive silicon visible light detectors... using 2 slightly different wavelengths creates 25X longer synthetic wavelength"
