Exponential gain in clock precision using quantum correlated ticks
Florian Meier, Yuri Minoguchi, Gianmichele Blasi +2
Creating precise timing devices at ultra-short time scales is not just an important technological challenge, but confronts us with foundational questions about timekeeping's ultima…

Cooling a Qubit using n Others
Jake Xuereb, Benjamin Stratton, Alberto Rolandi +3
In the task of unitarily cooling a quantum system with access to a larger quantum system, known as the machine or reservoir, how does the structure of the machine impact an agent's…

Entropic costs of extracting classical ticks from a quantum clock
Vivek Wadhia, Florian Meier, Federico Fedele +12
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'…
