Fundamental Limitation on the Detectability of Entanglement. (arXiv:2208.02518v1 [quant-ph]) 上午10:42 | Pengyu Liu, Zhenhuan Liu, Shu Chen, Xiongfeng Ma | quant-ph updates on arXiv.org Entanglement detection is essential in quantum information science and quantum many-body physics. It has been proved that entanglement exists almost surely for a random quantum state, while the realizations of effective entanglement criteria usually consume exponential… Read more →

Time-energy uncertainty relation for noisy quantum metrology. (arXiv:2207.13707v1 [quant-ph]) 上午9:19 | Philippe Faist, Mischa P. Woods, Victor V. Albert, Joseph M. Renes, Jens Eisert, John Preskill | quant-ph updates on arXiv.org Detection of weak forces and precise measurement of time are two of the many applications of quantum metrology to science and technology. We consider a quantum system initialized in… Read more →

Gravity entanglement, quantum reference systems, degrees of freedom. (arXiv:2207.03138v1 [quant-ph]) 上午9:51 | Marios Christodoulou, Andrea Di Biagio, Richard Howl, Carlo Rovelli | quant-ph updates on arXiv.org We discuss the physical interpretation of the gravity mediated entanglement effect. We show how to read it in terms of quantum reference systems. We pinpoint the single gravitational degree of freedom mediating the entanglement…. Read more →

Reply to the comment on “Quantum priniple of relativity”. (arXiv:2206.15247v1 [quant-ph]) 上午9:48 | Andrzej Dragan, Artur Ekert | quant-ph updates on arXiv.org We refute criticisms by Del Santo and Horvat towards our paper “Quantum principle of relativity”: most of their counterarguments can be dismissed, and the rest provides further evidence to our claims. Stochastic Bohmian and Scaled Trajectories. (arXiv:2206.15260v1 [quant-ph])… Read more →

A note on the inner products of pure states and their antidistinguishability. (arXiv:2206.08313v1 [quant-ph]) 上午11:01 | Vincent Russo, Jamie Sikora | quant-ph updates on arXiv.org A set of d quantum states is said to be antidistinguishable if there exists a d-outcome POVM that can perfectly identify which state was not measured. A conjecture by Havl\’i\v{c}ek and Barrett states that if… Read more →

Causality, unitarity and stability in quantum gravity: a non-perturbative perspective. (arXiv:2206.04072v1 [hep-th]) 上午9:50 | gr-qc updates on arXiv.org Authors: Alessia Platania Resumming quantum fluctuations at the level of the gravitational path integral is expected to result in non-local effective actions and thus in a non-trivial momentum dependence of the propagator. Which properties the (dressed) graviton propagator has to satisfy and whether… Read more →
