Quantum-enhanced imaging and sensing

Since a few years the growing exploitation of quantum states led to many sophisticated and novel applications. Non-classical states of light promise a phase sensitivity beyond any classical possibility and super-resolution capability. Moreover, based on quantum correlations, which are rooted in the very heart of quantum mechanics, the imaging of samples with photons that have never interacted with the object is feasible. This way it becomes possible to perform extreme wavelength illumination at very low photon dose without compromising the detection efficiency, since the camera sensor receives the photons at their maximum efficiency wavelength in the VIS, which can enhances the signal-to-noise ratio, too. Moreover, since the spectral fingerprint rang becomes accessible, a new tool for label-free chemical-selective imaging becomes available.

Der Vortrag wird  online per Zoom übertragen und kann auch im live-Stream des MMZ verfolgt werden.
