Quantum Light for New Imaging for Early and Differentiated Detection of Biomarkers in Personalised Medicine (QUEED)

The QUEED project focuses on quantum sensing with entangled photons for applications in medical research and cancer diagnostics. Funded for five years, the collaboration will jointly develop a high-performance microscope capable of operating in the mid-infrared (MIR). In order to transfer measurement information from the clinically relevant MIR into the near-infrared (NIR), which can be detected particularly quickly and with low noise, a novel spectrally resolving imaging method based on entangled photon pairs will be used.

Within the Nonlinear Quantum Optics group at the Department of Physics and IRIS Adlershof at HU Berlin, led by Dr Sven Ramelow – who also serves as Scientific Director of the overall collaboration – high-performance quantum interferometer modules are being developed, and the quantum-sensing measurement techniques underlying the collaborative project are being optimised. The core innovation lies in the significant increase in the rate of generated entangled photon pairs, as well as the substantial extension of the MIR measurement range compared to the current state of the art.
