- Abstract: A newfound security breach in the physical nature of single photon detectors
that are generally used in quantum key distribution is explained, we found that
the bit contents of a quantum key transmission system can be intercepted from
far away by exploiting the ultrawideband electromagnetic signals radiated from
hi-voltage avalanche effect of single photon detectors. It means that in fact
any Geiger mode avalanche photodiode that is used inside single photon
detectors systematically acts like a downconverter that converts the
optical-wavelength photons to radio-wavelength photons that can be intercepted
by an antenna as side channel attack. Our experiment showed that the radiated
waveforms captured by the antenna can be used as a fingerprint. These finger
prints were fed to a deep learning neural network as training data, and after
training the neural network was able to clone the bit content of quantum
transmission.

Microwave or radio-frequency driving poses a significant limitation for miniaturization, energy-efficiency and non-invasiveness of quantum sensors.
We overcome this limitation by demonstrating a purely optical approach to coherent quantum sensing.
Our results pave the way for highly compact quantum sensors to be employed for magnetometry or gyroscopy applications.
