- Abstract: Some deep conjectures about quantum gravity are closely related to the role
of symmetries in the gravitational background, especially for quantum black
holes. In this paper, we systematically study the theory of quantum information
for a charged, chaotic system. We show how the quantum information in the whole
system has been represented by its charge sectors, using the theory of quantum
chaos and quantum error correction, with concrete examples in the context of
the complex SYK model. We discuss possible implications for black hole thought
experiments and conjectures about quantum gravity in the dynamical setup. We
believe this work will have potential applications from theories of quantum
gravity to quantum simulation in quantum devices.

We explore the applicability of quantum-data learning to practical problems in high-energy physics.
We make use of ansatz based on quantum convolutional neural networks and numerically show that it is capable of recognizing quantum phases of ground states.
The observation of non-trivial learning properties demonstrated in these benchmarks will motivate further exploration of the quantum-data learning architecture in high-energy physics.

We show that quantum systems undergo corrections to the quantum speed limit which, in turn, imply the modification of the Heisenberg limit for parameter estimation.
For some nonlocal models inspired by quantum gravity, the bounds are found to oscillate in time, an effect that could be tested in future high-precision quantum experiments.

We find that the quantum simulator results can indeed be explained by the KZM for open-system quantum dynamics with phase-flip errors.
This implies that the theoretical predictions of the generalized KZM theory, which assumes isolation from the environment, applies beyond its original scope to an open system.
