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

QET Labs contingent for the EntangleCam exhibit at The Royal Society Summer Science Exhibition! Come see us over the weekend in London and hear about quantum tech for healthcare and sensing! @qetlabs.bsky.social @imperialcollegeldn.bsky.social @uofglasgow.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

Massive congratulations to our inspiring PhD student Suruchi Bala for winning the @bristoluni.bsky.social Bristol Teaching Award for Inspiring and Innovative Teaching - PGRs who teach! 🥳 A fantastic achievement that recognises Suruchi's commitment to pedagogical practice and innovative approaches.

Postdoc Job Alert! Come and work in my group at the cutting edge of interfacing atomic #quantum memories with single #photon emitters! Closing date: 17th June. See here: www.bristol.ac.uk/jobs/find/de... @qetlabs.bsky.social @qusit.bsky.social @qepnthub.bsky.social @qqq-iop.bsky.social

Closing remarks from the QET Labs director @dralexclark.bsky.social wraps up BQIT:25. Thanks to all our speakers, exhibitors, poster-presenters and visitors for an enjoyable and engaging few days! See you next year for #BQIT 26!

BQIT:25 sponsors IDQuantique believe that the ability to trust networks and communicate securely is a fundamental human right. Visit their stand at our workshop this week to learn more. See the website for more information: idquantique.com

@psiquantum.bsky.social’s Jonathan Matthews spoke at BQIT:25 yesterday on the company’s approach to building a utility-scale, fault-tolerant quantum computer, involving photonics-based architecture leveraging existing infrastructure to build and scale as fast as possible: psiquantum.com

That’s a wrap on Day 1 of BQIT:25!

A great day of talks, covering topics from error correction to solid-state quantum emitters and quantum networks.

Tomorrow, we’ll hear about the latest developments in areas such as quantum sensing, quantum computing, integrated photonics, and cold atoms.
