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...

FLQT 2025 — ASPECTS Fundamental Limits of Quantum Technologies conference, Dublin, 25-29 August 2025

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

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

✨
✅ First experiment linking entropy production in a microscopic clock to macroscopic measurement.
✅ Precision improves as the measurement process dominates energy costs.
✅ The thermodynamic cost of recording time may be more fundamental than the clock itself.

Entropic costs of the quantum-to-classical transition in a microscopic clock We experimentally realize a quantum clock by using a charge sensor to count charges tunneling through a double quantum dot (DQD). Individual tunneling events are used as the clock's ticks. We quantify...

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

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.

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

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.
