Abstract: We quantize the solution to the Belinski-Khalatnikov-Lifshitz (BKL) scenario using the integral quantization method. Quantization smears the gravitational singularity avoiding its localization in the configuration space. The latter is defined in terms of spatial and temporal coordinates, which are treated on the same footing that enables respecting covariance of general relativity. The relative quantum perturbations grow as the system evolves towards the gravitational singularity. The quantum randomness amplifies the deterministic classical chaos of the BKL scenario. Additionally, our results suggest that the generic singularity of general relativity can be avoided at quantum level giving support to the expectation that quantum gravity has good chance to be a regular theory.

To be or not to be, but where? [0.0]
Traditional approaches associate quantum systems with classical ones localized in spacetime. canonical linearized quantum gravity disrupts this framework by preventing the formation of gauge-in-variant local algebras. This presents a major obstacle for modeling early universe cosmology, gravity-entanglement experiments, and poses a significant roadblock toward a comprehensive theory of quantum gravity.

Relativistic Dips in Entangling Power of Gravity [0.0]
We show that quantum correlations can remain strongly suppressed for certain choices of parameters. We find a pronounced cancellation point far from the Planck scale, where the system tends towards classicalization.

A Realist Interpretation of Unitarity in Quantum Gravity [0.0]
Unitarity is a difficult concept to implement in canonical quantum gravity because of state non-normalizability and the problem of time. We use the postulate of a definite configuration in the theory to define a global time for the gravitational-fermionic system. We find unitary states in mini-superspace by finding an approximate solution to the Hamiltonian constraint.

Does the Universe have its own mass? [62.997667081978825]
The mass of the universe is a distribution of non-zero values of gravitational constraints. A formulation of the Euclidean quantum theory of gravity is also proposed to determine the initial state. Being unrelated to ordinary matter, the distribution of its own mass affects the geometry of space.

Probabilistic deconstruction of a theory of gravity, Part II: curved space [0.0]
We show that volume measure of spacetime is a probability measure constrained by quantum dynamics. We conjecture that general relativity arises in the semi-classical limit of the evolution of probability with respect to quantum processes.

Quantum Instability [30.674987397533997]
We show how a time-independent, finite-dimensional quantum system can give rise to a linear instability corresponding to that in the classical system. An unstable quantum system has a richer spectrum and a much longer recurrence time than a stable quantum system.

Quantum Causal Inference in the Presence of Hidden Common Causes: an Entropic Approach [34.77250498401055]
We put forth a new theoretical framework for merging quantum information science and causal inference by exploiting entropic principles. We apply our proposed framework to an experimentally relevant scenario of identifying message senders on quantum noisy links. This approach can lay the foundations of identifying originators of malicious activity on future multi-node quantum networks.
