ASPECTS Principal Investigator, Natalia Ares, kicks off our 4th day of FLQT, introducing invited speaker Nikolai Kiesel. Find out more: www.aspects-quantum.com/flqt2025

🔍 How uncertain can quantum systems be? Saulo Moreira shares work developing new bounds that show how quantum effects—like coherence and correlations—can break classical limits on uncertainty. This helps us better understand how quantum systems behave when measured.

Emanuel Schwarzhans discusses how entropy production powers detection—and limits it. Efficiency, jitter, dead time, dark counts: all tied to thermodynamic cost.

What defines a clock in quantum mechanics? Paul Erker explores the minimal ingredients for timekeeping in the quantum regime, introducing autonomous quantum clocks and the thermodynamic trade-offs that constrain their precision. A deep dive into time, entropy, and the limits of quantum tech.

ASPECTS' Javier Prior presents his team's work looking at how strong coupling reshapes heat flow in open quantum systems—exploring non-Markovian effects, coherence-driven fluctuations & new equilibrium states.

🕰️ What’s the real cost of reading time? ASPECTS experiment reveals that the measurement of quantum ticks—not their generation—is the dominant source of entropy in quantum timekeeping. Far from wasteful, this quantum-to-classical transition boosts precision. #FLQT2025

So many great talks at Fundamental Limits of Quantum Technologies already, and many more yet to come! Here’s Shane Dooley of DIAS telling us about metrology using many-body quantum systems 🤩 www.aspects-quantum.com/flqt2025 @aspects-quantum.bsky.social

Fresh on arXiv! arxiv.org/abs/2508.16375 By casting detectors as autonomous thermal machines, we uncover the link between entropy production and the detector’s efficiency, timing jitter, dead time and dark counts. Outstanding work by Manu Schwarzhans with my @aspects-quantum.bsky.social friends ❤️

Last chance to avail of the early bird registration discount for FLQT 2025, which ends this week!!

We are excited for Fundamental Limits of Quantum Technologies conference, Dublin, 25-29 August. Only three weeks left until the abstract submission deadline, don't delay! All details at www.aspects-quantum.com/flqt2025

What started as informal discussions on the Danube beach in Vienna during QTD2023 has been published at last. Trying to come up with an experimentally feasible quantum clock we came across a rich model – the ring clock – that overturned a common wisdom in the community. doi.org/10.1038/s415...

Don't forget to submit your abstract for our conference in Dublin, August 2025! www.aspects-quantum.com/flqt2025
