Multi-parameter two-photon polarimetry at the quantum limit
Joseph Niblo, Luca Maggio, Russell M. J. Brooks +3
Photonic quantum metrology has demonstrated advantages in precision and resource efficiency for a wide range of applications, with several schemes approaching the fundamental quant…
Decoy-state quantum key distribution over 227 km with a frequency-converted telecom single-photon source
Frederik Brooke Barnes, Roberto G. Pousa, Christopher L. Morrison +7
We implement a decoy-state quantum key distribution scheme using a telecom C-band single-emitter source. The decoy states are created by varying the optical excitation of the quant…
Quantum-private distributed sensing
Joseph Ho, Jonathan W. Webb, Russell M. J. Brooks +3
Quantum networks can enhance both security and privacy conditions for multi-user communication, delegated computation, and distributed sensing tasks. An example quantum protocol is…
Quantum-limited optical delay sensing across an enhanced dynamic range by frequency-resolving two-photon interference
Russell M. J. Brooks, Luca Maggio, Thomas Jaeken +4
Optical sensing schemes that rely on two-photon interference provide a powerful platform for precision metrology, although they are inherently constrained by a trade-off between dy…
