Entropic Lower Bound for Distinguishability of Quantum States by Seungho Yang, Jinhyoung Lee, Hyunseok Jeong

“…For a system randomly prepared in a number of quantum states, we present a lower bound for the distinguishability of the quantum states, that is, the success probability of determining the states in the form of entropy. …”

The Quantum Effect on Friedmann Equation in FRW Universe by Wei Zhang, Xiao-Mei Kuang

“…We study the modified Friedmann equation in the Friedmann-Robertson-Walker universe with quantum effect. Our modified results mainly stem from the new entropy-area relation and the novel idea of Padmanabhan, who considers the cosmic space to be emerging as the cosmic time progresses, so that the expansion rate of the universe is determined by the difference of degrees of freedom between the holographic surface and the bulk inside. …”

Quantum and Classical Dynamics with Random Permutation Circuits by Bruno Bertini, Katja Klobas, Pavel Kos, Daniel Malz

“…We show that, upon averaging over all circuit realizations, RPCs permit the analytical computation of several key quantities such as out-of-time-order correlators (OTOCs) and entanglement entropies. In the classical setting, we obtain similar exact results relating (quantum) purity to (classical) growth of mutual information and (quantum) OTOCs to (classical) decorrelators. …”

Local Channels under Decomposition of Quantum Gates in Bipartite Systems by Yihui Lao, Pei Wang, Shanli Liao

“…Within this class of quantum channels, the paper characterizes those channels which preserve the Tsallis entropy of combinations of separable states through decomposing quantum gates, where the characterization is given in terms of the action of the channel on separable states.…”

Probing the Page transition via approximate quantum error correction by Haocheng Zhong

“…In the paper, we find that the black hole evaporation interpreted by the island formula can be understood in the language of approximate quantum error correction. Furthermore, the Page transition, as a special property of the Page curve, should be understood as the property of approximate quantum error correction itself, i.e. a general class of quantum systems under certain conditions from approximate quantum error correction can also exhibit phenomenon similar to the Page transition.…”

A thermodynamically consistent approach to the energy costs of quantum measurements by Camille L Latune, Cyril Elouard

“…Considering a general microscopic model for a quantum measuring apparatus comprising a quantum probe coupled to a thermal bath, we analyze the energetic resources necessary for the realization of a quantum measurement, which includes the creation of system-apparatus correlations, the irreversible transition to a statistical mixture of definite outcomes, and the apparatus resetting. …”

Initiating the Effective Unification of Black Hole Horizon Area and Entropy Quantization with Quasi-Normal Modes by C. Corda, S. H. Hendi, R. Katebi, N. O. Schmidt

“…Black hole (BH) area quantization may be the key to unlocking a unifying theory of quantum gravity (QG). Surmounting evidence in the field of BH research continues to support a horizon (surface) area with a discrete and uniformly spaced spectrum, but there is still no general agreement on the level spacing. …”
