🔍 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.

🕰️ 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

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 ❤️
Illustration of the three-way trade off between dark count rate (top), detection time uncertainty (jitter, bottom left) and dead time (bottom right). These cannot all be simultaneously improved, but must be traded off against one another, if the detector’s rate of steady-state entropy production (centre) is fixed.

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...

Latest preprint from the ASPECTS consortium! arxiv.org/abs/2502.00096 Experiments by the amazing @naresgroup.bsky.social and theory by @mathsmire.bsky.social of @quitphysics.info We measured the entropy cost of generating and recording ticks in a microscopic clock 1/6 🧵👇
Depiction of the quantum-classical transition in a microscopic clock. A quantum clock transitions between three discrete states, driven by thermal noise. These transitions are amplified by a sensor into a classical signal, which can be shared among classical observers as an objective record of the passage of time.
