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

Simon Sundelin kicks off our ASPECTS day at the FLQT conference. Learn more here: www.aspects-quantum.com/flqt2025

I'll be giving a talk at FLQT next week! www.aspects-quantum.com/flqt2025 Anyone else going?

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!!

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

Had lots of fun with @khalak.bsky.social, recording the Gujarati, Hindi and Portuguese versions of "Quantum Quest - Hide and Seek", the upcoming animation currently being developed by Cassete Vision's amazingly talented team 👀🐈‍⬛ @aspects-quantum.bsky.social 📷: Adam Rael

We’re organising a conference in Dublin! Fundamental Limits of Quantum Technologies 2025 — everything from error mitigation on NISQ devices, through control constraints on complex quantum systems, to quantum thermodynamics and energetics, and much more! Abstract submission and registration open! 👇

Pauli Erker giving a wonderful invited talk on the autonomous quantum processing unit arxiv.org/abs/2402.00111, part of an inspiring session on Time in Quantum Mechanics and Thermodynamics at #APSSummit2025

At #APS watching Simon Sundelin nailing his talk on our @aspects-quantum.bsky.social collaboration 😍

ASPECTS goes to March Meeting, aka APS Global Physics Summit! Catch five of our researchers at the following sessions:

Introducing our quantum clock using charge tunneling in a double quantum dot (DQD), where each tunneling event acts as a "tick." Read more: arxiv.org/abs/2502.16667

An interesting new article, introducing MetaSym, a deep learning model that learns physics better by preserving key properties like energy & momentum. Read more here: arxiv.org/abs/2502.16667

The ASPECTS consortium is funded by the Quantum Flagship @ec.europa.eu – you can check out all of our activities here! www.aspects-quantum.com 6/6

🔥 🕰️ Read our new paper on the thermodynamics of clocks 🔥🕰️https://arxiv.org/abs/2502.00096 @mitchison.bsky.social @entangledanarchist.bsky.social

Our Dublin team launched their children’s story “Quantum Quest” cowritten with the fabulous @FightingWordsIE team, check it out here: www.fightingwords.ie/publications...

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 🧵👇

We met with the Amber Centre EPE team, Screen Ireland and Cassette Vision to brainstorm how to explain quantum concepts through an animated video for school children. This builds off of the success of their recent Quantum Quest storybook.
