How do I introduce Schr\”odinger equation during the quantum mechanics course?. (arXiv:2010.15589v1 [physics.ed-ph]) 上午10:31 | T. Mart | quant-ph updates on arXiv.org In this paper I explain how I usually introduce the Schr\”odinger equation during the quantum mechanics course. My preferred method is the chronological one. Since the Schr\”odinger equation belongs to a special case of wave equations I start… Read more →
Everettian probabilities, the Deutsch-Wallace theorem and the Principal Principle. (arXiv:2010.11591v1 [quant-ph]) 2020年10月23日 星期五 下午4:54 | Harvey R. Brown, Gal Ben Porath | quant-ph updates on arXiv.org This paper is concerned with the nature of probability in physics, and in quantum mechanics in particular. It starts with a brief discussion of the evolution of Itamar Pitowsky’s thinking about probability in quantum… Read more →

Quantum measurement incompatibility in subspaces. (arXiv:2010.04048v1 [quant-ph]) 上午9:34 | Roope Uola, Tristan Kraft, Sébastien Designolle, Nikolai Miklin, Armin Tavakoli, Juha-Pekka Pellonpää, Otfried Gühne, Nicolas Brunner | quant-ph updates on arXiv.org We consider the question of characterising the incompatibility of sets of high-dimensional quantum measurements. We introduce the concept of measurement incompatibility in subspaces. That is, starting from a set of… Read more →

Towards the Heisenberg limit in microwave photon detection by a qubit array. (arXiv:2009.11271v2 [quant-ph] UPDATED) 上午9:49 | P. Navez, A. G. Balanov, S. E. Savel’ev, A. M. Zagoskin | quant-ph updates on arXiv.org Using an analytically solvable model, we show that a qubit array-based detector allows to achieve the fundamental Heisenberg limit in detecting single photons. In case of superconducting… Read more →
Finding the world in the wave function: some strategies for solving the macro-object problem 上午8:00 | Latest Results for Synthese Abstract Realists wanting to capture the facts of quantum entanglement in a metaphysical interpretation find themselves faced with several options: to grant some species of fundamental nonseparability, adopt holism, or (more radically) to view localized spacetime systems as ultimately reducible… Read more →

Violation of Heisenberg’s Error-Disturbance Relation by Stern-Gerlach Measurements. (arXiv:2009.01646v1 [quant-ph]) 上午10:15 | Yuki Inoue, Masanao Ozawa | quant-ph updates on arXiv.org Although “Heisenberg’s uncertainty principle” is represented by a rigorously proven relation about intrinsic indeterminacy in quantum states, Heisenberg’s error-disturbance relation (EDR) has been commonly believed as another aspect of the principle. However, recent developments of quantum measurement theory made… Read more →
Meaning relativism and subjective idealism 上午8:00 | Latest Results for Synthese Abstract The paper discusses an objection, put forward by—among others—John McDowell, to Kripke’s Wittgenstein’s non-factualist and relativist view of semantic discourse. The objection goes roughly as follows: while it is usually possible to be a relativist about a given domain of discourse without being a relativist about anything else,… Read more →
