On the significance of Wigner's Friend in contexts beyond quantum foundations [PDF]
QuantumThere has been a surge of recent interest in the Wigner's Friend paradox, sparking several novel thought experiments and no-go theorems. The main narrative has been that Wigner's Friend highlights a counterintuitive feature that is unique to quantum ...

Kirkwood-Dirac quasiprobability approach to the statistics of incompatible observables [PDF]
Quantum, 2023 Recent work has revealed the central role played by the Kirkwood-Dirac quasiprobability (KDQ) as a tool to properly account for non-classical features in the context of condensed matter physics (scrambling, dynamical phase transitions) metrology ...

Frontiers in Physics, 2020 Quantum mechanics has irked physicists ever since its conception more than 100 years ago. While some of the misgivings, such as it being unintuitive, are merely aesthetic, quantum mechanics has one serious shortcoming: it lacks a physical description of ...

Thermodynamic state convertibility is determined by qubit cooling and heating
New Journal of Physics, 2023 Thermodynamics plays an important role both in the foundations of physics and in technological applications. An operational perspective adopted in recent years is to formulate it as a quantum resource theory.

Bell’s theorem and the foundations of quantum physics [PDF]
American Journal of Physics, 1985 A locality property expressing the idea that causal influences can propagate only forward in time, from earlier cause to later effect, and no faster than light is shown to be mathematically incompatible with certain predictions of quantum theory. The contradiction is proved without invoking any additional assumptions such as realism or hidden variables

Timelessness Strictly inside the Quantum Realm
Entropy, 2021 Time is one of the undisputed foundations of our life in the real world. Here it is argued that inside small isolated quantum systems, time does not pass as we are used to, and it is primarily in this sense that quantum objects enjoy only limited reality.

Quantum-like Modeling of Cognition
Frontiers in Physics, 2015 This paper begins with a historical review of the mutual influence of physics and psychology, from Freud's invention of psychic energy inspired by von Boltzmann' thermodynamics to the enrichment quantum physics gained from the side of psychology by the ...

Strongly Continuous Representations in the Hilbert Space: A Far-Reaching Concept
Universe, 2021 We revisit the fundamental notion of continuity in representation theory, with special attention to the study of quantum physics. After studying the main theorem in the context of representation theory, we draw attention to the significant aspect of ...
