Abstract
The reconciliation of general relativity with quantum mechanics is conventionally sought through the quantization of the gravitational field. The approach taken here differs from canonical quantization by treating the metric as an irreducibly stochastic classical field. By merging the post-quantum theory of gravity with the Diósi-Penrose model, we introduce a Gravitational Complexity Bound. Consistency of a classical spacetime coupled to quantum matter requires the metric tensor to fluctuate. These fluctuations induce a non-Markovian noise floor that scales non-linearly with the number of entangled qubits. This decoherence is intrinsic to the geometry and cannot be mitigated by electromagnetic shielding. We derive a critical threshold, N

, beyond which the rate of gravitational information loss exceeds the capacity of any local quantum error-correcting code. Applying this framework to the black hole information paradox indicates that the event horizon behaves as a Complexity Horizon-a surface at which the vacuum's computational capacity saturates and information is scrambled into the stochastic background.
We show that gravitational curvature can control the generation of nonlocal quantum correlations in a hybrid qubit-mechanical device. The tidal field of a nearby source mass modifies the susceptibility of a shared mechanical oscillator, thereby tuning an oscillator-mediated qubit-qubit interaction and the resulting ent...

The quantum geometric tensor - the Berry curvature together with the quantum metric - now underlies a long list of observables, from the anomalous Hall effect to the superfluid weight of a flat band. We ask which of these observables actually require quantum mechanics. To answer this question, we study a purely classic...
In this work, we propose a notion called effective distance to characterize the essential gravitational effects on quantum coherence of neutrinos. Employing effective distances, we prove that one can always map neutrino-oscillation phases in asymptotically flat spacetimes onto the phases in flat spacetime, which is con...
Part I: Semiclassical Gravity Efficiently Solves $\mathsf{NP}$-Complete Problems Assuming the gravitational field is classical and that it couples to quantum fields via the semiclassical Einstein field equations (EFEs), we show that the weak-field dynamics of a massive and non-relativistic qubit can in principle be use...
The nature of spacetime in quantum gravity remains a fundamental problem, rooted in the conflict between the background independence of general relativity and the fixed-background structure of quantum field theory. This paper proposes a concrete, emergentist framework in which classical continuous spacetime is not fu...

Black holes sit at the sharpest intersection of quantum mechanics, gravity, and statistical physics. Quantum theory demands unitary time evolution: a closed system evolves by a unitary operator and therefore preserves information. Classical general relativity, however, suggests that a black hole hides information behin...
