Certifying dimension of quantum systems by sequential projective measurements

Adel Sohbi et al.

Summary: This work analyzes correlations arising from quantum systems subject to sequential projective measurements to certify quantum dimensions greater than a certain value. The study refines previous methods and demonstrates that dimensions greater than two can be certified in simpler scenarios than before, while also certifying quantum systems with dimensions strictly greater than three for the first time in this sequential projective scenario. Additionally, a systematic numerical analysis on robustness shows that performing random projective measurements on random pure qutrit states allows a robust certification of quantum dimensions with very high probability.

Autonomous Ticking Clocks from Axiomatic Principles

Mischa P. Woods

Summary: This paper introduces a new ticking clock model that aims to address concerns about the physicality of assumptions made in previous models. The new model combines the autonomy of a less accurate model with the high accuracy of another model, achieving the best of both worlds. Additionally, it is shown that the less accurate model is a special case of the new ticking clock model.

Autonomous Temporal Probability Concentration: Clockworks and the Second Law of Thermodynamics

Emanuel Schwarzhans et al.

Summary: According to thermodynamics, the increase of entropy distinguishes the past from the future, requiring any clock to incorporate an irreversible process to track this flow. A clockwork, a system designed to concentrate irreversible events and improve the accuracy of time measurements, is essential for a clock. By increasing complexity, an ideal clockwork model can be approximated, showcasing the thermodynamic limits of time measurement when combined with irreversible decay mechanisms.

Measuring the Thermodynamic Cost of Timekeeping

A. N. Pearson et al.

Summary: Research demonstrates that there is a linear relationship between the accuracy of clocks and entropy, with experimental measurements showing this relationship exists in nanoscale clocks and operates within an order of magnitude of the theoretical limit.
