An equivalence between time-symmetry and cyclic causality in quantum theory
Eliot Jean, Ralph Silva, V. Vilasini
Understanding the relationship between the time-symmetric nature of physical laws and the apparent directionality of causality is a central question in quantum foundations. The sta…
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'…
Optimal unitary trajectories under commuting target and cost observables; applications to cooling
Ralph Silva, Pharnam Bakhshinezhad, Fabien Clivaz
The preparation of quantum states, especially cooling, is a fundamental technology for nanoscale devices. The past decade has seen important results related to both the limits of s…
Tomography of clock signals using the simplest possible reference
Nuriya Nurgalieva, Ralph Silva, Renato Renner
We show that finite physical clocks always have well-behaved signals, namely that every waiting-time distribution generated by a physical process on a system of finite size is guar…
Optimal time estimation and the clock uncertainty relation for stochastic processes
Kacper Prech, Gabriel T. Landi, Florian Meier +4
Time estimation is a fundamental task that underpins precision measurement, global navigation systems, financial markets, and the organisation of everyday life. Many biological pro…
