Title: Quantum gravity as a communication resource
Authors: Richard Howl, Ali Akil, Hlér Kristjánsson, Xiaobin Zhao, Giulio Chiribella,
Abstract summary: We show that quantum coherence in black hole, and thus spacetime, can limit the degradation of entanglement. This finding indicates that quantum features of spacetime could serve as resources for quantum information processing.

Abstract: Quantum information can provide a lens for characterizing the operational implications of spacetime physics. A well-known result in this area is that quantum entanglement is degraded in the vicinity of a black hole. This result treats the black hole and its spacetime as classical. But what if these were to be treated quantum-mechanically? Here, we show that quantum coherence in black hole, and thus spacetime, degrees of freedom can limit the degradation of entanglement, thereby improving the performance of nearby quantum communication protocols. This finding indicates that quantum features of spacetime could serve as resources for quantum information processing.

Quantum data learning for quantum simulations in high-energy physics [55.41644538483948]
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.

Black Holes Decohere Quantum Superpositions [0.0]
We show that if a massive body is put in a quantum superposition of spatially separated states, the mere presence of a black hole in the vicinity of the body will eventually destroy the coherence of the superposition. This occurs because, in effect, the gravitational field of the body radiates soft gravitons into the black hole, allowing the black hole to acquire "which path" information about the superposition.

Quantum signatures of black hole mass superpositions [0.0]
We apply our approach to analyze the dynamics of a detector in a spacetime generated by a BTZ black hole in a superposition of masses. We find that the detector exhibits signatures of quantum-gravitational effects corroborating Bekenstein's seminal conjecture concerning the quantized mass spectrum of black holes in quantum gravity.
