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…
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'…
Autonomous Quantum Processing Unit: An Autonomous Thermal Computing Machine & its Physical Limitations
Florian Meier, Marcus Huber, Paul Erker +1
Computation is an input-output process, where a program encoding a problem to be solved is inserted into a machine that outputs a solution. Quantum computation conventionally relie…
Energy-Consumption Advantage of Quantum Computation
Florian Meier, Hayata Yamasaki
Energy consumption in solving computational problems has been gaining growing attention as one of the key performance measures for computers. Quantum computation is known to offer…
Optimal limits of continuously monitored thermometers and their Hamiltonian structure
Mohammad Mehboudi, Florian Meier, Marcus Huber +1
We investigate the fundamental and practical precision limits of thermometry in bosonic and fermionic environments by coupling an -level probe to them and continuously monitorin…
Emergence of a second law of thermodynamics in isolated quantum systems
Florian Meier, Tom Rivlin, Tiago Debarba +3
The second law of thermodynamics states that the entropy of an isolated system can only increase over time. This appears to conflict with the reversible evolution of isolated quant…
