🔍 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’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

✨Highlights: ✅ 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 extracting classical ticks from a quantum 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...
