Open-Path Methane Sensing via Backscattered Light in a Nonlinear Interferometer Nonlinear interferometry has widespread applications in sensing, spectroscopy, and imaging. However, most implementations require highly reflective mirrors and precise optical alignment, drastically r...

Another excellent result posted to the arXiv today! We replace the mirror in our methane sensing nonlinear interferometer with paper, and it can still sense the background methane in the room and is more robust to misalignment! arxiv.org/abs/2506.17107 @qetlabs.bsky.social @qusit.bsky.social

The arXiv papers keep coming! This time an amazing demonstration of entanglement-inspired rangefinding between different buildings across Bristol! We use low light levels and single photon detection, but operate in daylight! arxiv.org/pdf/2506.11980 @qepnthub.bsky.social @qetlabs.bsky.social

Phase Matching Free Sensing with Undetected Light Using a Nonlinear Metasurface In this letter, we report classical sensing with undetected light using octave spanning stimulated four-wave mixing from a plasmonic metasurface. The bidirectional nonlinear scattering due to inherent...

New arXiv paper! We use a plasmonic metasurface to demonstrate pulsed nonlinear interference via double-pass stimulated four-wave mixing! See here: arxiv.org/abs/2506.01175. Collaboration between ICL, QET Labs, and NTU. @qetlabs.bsky.social @imperialcollegeldn.bsky.social @qusit.bsky.social
