High transmission-loss and classical-quantum multiplexing QKD enabled with short wavelength photons - Thomas Jennewein

I will present recent results on quantum key distribution (QKD) using short optical wavelengths (532nm, 810 nm). These wavelengths offer unique applications such as operation with ultra-high channel losses of 60dB, and entanglement based QKD over existing IT infrastructure by multiplexing classical and quantum signals on the same optical fibre.
