Measuring time with stationary quantum clocks
Sergii Strelchuk, Mischa P. Woods
Time plays a fundamental role in our ability to make sense of the physical laws in the world around us. The nature of time has puzzled people -- from the ancient Greeks to the pres…
Autonomous Ticking Clocks from Axiomatic Principles
Mischa P. Woods
There are many different types of time keeping devices. We use the phrase ticking clock to describe those which -- simply put -- "tick" at approximately regular intervals. Various…
Universal quantum modifications to general relativistic time dilation in delocalised clocks
Shishir Khandelwal, Maximilian P. E. Lock, Mischa P. Woods
The theory of relativity associates a proper time with each moving object via its world line. In quantum theory however, such well-defined trajectories are forbidden. After introdu…
Continuous groups of transversal gates for quantum error correcting codes from finite clock reference frames
Mischa P. Woods, Álvaro M. Alhambra
Following the introduction of the task of reference frame error correction, we show how, by using reference frame alignment with clocks, one can add a continuous Abelian group of t…
Resource theory of quantum thermodynamics: Thermal operations and Second Laws
Nelly Ng, Mischa P. Woods
Resource theories are a generic approach used to manage any valuable resource, such as entanglement, purity, and asymmetry. Such frameworks are characterized by two main elements:…
