Entanglement, Complexity, and Causal Asymmetry in Quantum Theories. (arXiv:2204.06742v1 [physics.hist-ph]) 上午8:51 | Porter Williams | quant-ph updates on arXiv.org It is often claimed that one cannot locate a notion of causation in fundamental physical theories. The reason most commonly given is that the dynamics of those theories do not support any distinction between the past and the future, and this… Read more →
From a microscopic inertial active matter model to the Schr\”odinger equation. (arXiv:2204.03018v1 [cond-mat.soft]) 上午9:17 | Michael te Vrugt, Tobias Frohoff-Hülsmann, Eyal Heifetz, Uwe Thiele, Raphael Wittkowski | quant-ph updates on arXiv.org Field theories for the one-body density of an active fluid, such as the paradigmatic active model B+, are simple yet very powerful tools for describing phenomena such as motility-induced… Read more →
Accessing inaccessible information via quantum indistinguishability. (arXiv:2203.16592v1 [quant-ph]) 上午9:20 | Sebastian Horvat, Borivoje Dakić | quant-ph updates on arXiv.org Suppose that Alice stumbles upon a box containing some confidential information and wishes to read out the latter. The problem is that the box is practically unbreakable and the information is so encoded as not to leave any physical trace in… Read more →
On the Birth of the Universe and Time. (arXiv:2203.12984v1 [gr-qc]) 上午8:58 | Natalia Gorobey, Alexander Lukyanenko, A. V. Goltsev | quant-ph updates on arXiv.org A theory of the initial state of the universe is proposed within the framework of the Euclidean quantum theory of gravity. The theory is based on a quantum representation in which the action functional is implemented… Read more →

Projective measurement of black holes. (arXiv:2203.04968v1 [hep-th]) 上午9:52 | Beni Yoshida | quant-ph updates on arXiv.org We study the effect of projective measurements on the entanglement structure of quantum black holes. It is shown that the entanglement verification in monitored quantum circuits, recently discussed in condensed matter physics, is equivalent to the information recovery from a black hole with projective… Read more →
The two classes of hybrid classical-quantum dynamics. (arXiv:2203.01332v1 [quant-ph]) 上午9:50 | Jonathan Oppenheim, Carlo Sparaciari, Barbara Šoda, Zachary Weller-Davies | quant-ph updates on arXiv.org Coupling between quantum and classical systems is consistent, provided the evolution is linear in the state space, preserves the split of systems into quantum and classical degrees of freedom, and preserves probabilities. The evolution law must… Read more →
Measurement of Entangled State Before, During, and After a Proposed Entangled Two-Photon Molecular Excitation. (arXiv:2202.11764v1 [quant-ph]) 上午10:01 | Bryce P. Hickam, Manni He, Szilard Szoke, Scott Cushing | quant-ph updates on arXiv.org Entangled photon pairs are predicted to linearize and increase the efficiency of multiphoton absorption, allowing continuous wave laser diodes to drive ultrafast time-resolved spectroscopy, nonlinear photonics, and nonlinear… Read more →

Quantum correlations and ergotropy. (arXiv:2202.05050v1 [quant-ph]) 上午10:53 | Gianluca Francica | quant-ph updates on arXiv.org Understanding the role of classical and quantum correlations in work extraction is a problem of fundamental importance in thermodynamics. We approach this problem by considering that, in closed quantum systems, the maximum cyclic work extractable is equal to the ergotropy. Thus, we aim to identify… Read more →
