QMA Complete Quantum-Enhanced Kyber: Provable Security Through CHSH Nonlocality

Ilias Cherkaoui, Indrakshi Dey·Nov 15, 2025

Post-quantum cryptography (PQC) must secure large-scale communication systems against quantum adversaries where classical hardness alone is insufficient and purely quantum schemes remain impractical. Lattice-based key encapsulation mechanisms (KEMs) ...

The conditional probabilities and the empirical laws in a free scalar QFT in curved spacetime

Hideyasu Yamashita·Nov 15, 2025

Unlike QFT in Minkowski spacetime (QFTM), QFT in curved spacetime (QFTCS) suffers from a conceptual obscurity on the empirical (experimentally verifiable/falsifiable) laws. We propose to employ the notion of prior conditional probabilities to describ...

Transitional Bell Correlation from Dirac Wavepackets

Ju Gao, Fang Shen·Nov 15, 2025

We derive a closed-form expression for the Bell--CHSH correlation of entangled, counter-propagating electrons using realistic Dirac wavepackets and localized detection. In contrast to the conventional distance-independent result, the Bell parameter e...

Skyrmionic qubits stabilized by Dzyaloshinskii-Moriya interaction as platforms for qubits and quantum gates

Doru Sticlet, Romulus Tetean, Coriolan Tiusan·Nov 15, 2025

Quantum computation departs from the classical paradigm of deterministic, bit-based processing by exploiting inherently quantum phenomena such as superposition and entanglement. We propose a framework for qubit realization based on skyrmionic states ...

Survival of Hermitian Criticality in the Non-Hermitian Framework

Fei Wang, Guoying Liang, Zecheng Zhao +3 more·Nov 15, 2025

In this work, we investigate many-body phase transitions in a one-dimensional anisotropic XY model subject to a complex-valued transverse field. Within the biorthogonal framework, we calculate the ground-state correlation functions and entanglement e...

Entanglement degradation of static black holes in effective quantum gravity

Xiaobao Liu, Wentao Liu, Shu-Min Wu·Nov 15, 2025

Quantum information science has been broadly explored in Einstein gravity and in various modified gravity theories; however, its extension to quantum gravity settings remains largely unexplored. Motivated by this gap, in this paper we investigate the...

Scalable quantum error mitigation for dynamical decoupling

Weibin Ni, Zhijie Li, Guanyu Qu +5 more·Nov 15, 2025

Quantum coherence remains a fundamental challenge for advancing quantum technologies. Although dynamical decoupling can suppress decoherence noise, it frequently misestimates decoherence times due to control errors -- a previously underappreciated is...

Channel-Constrained Markovian Quantum Diffusion Model from Open System Perspective

Qin-Sheng Zhu, Geng Chen, Lian-Hui Yu +2 more·Nov 15, 2025

We present a channel-constrained Markovian quantum diffusion (CCMQD) model that prepares quantum states by rigorously framing the generative process within the dynamics of open quantum systems. Our model interprets the forward diffusion process as na...

Stochastic Shadow Descent: Training Parametrized Quantum Circuits with Shadows of Gradients

Sayantan Pramanik, M Girish Chandra·Nov 15, 2025

In this paper, we focus on the task of optimizing the parameters in Parametrized Quantum Circuits (PQCs). While popular algorithms, such as Simultaneous Perturbation Stochastic Approximation (SPSA), limit the number of circuit-execution to two per it...

Application of optical squeezing to microresonator based optical sensors

Dariya Salykina, Daniil Shakhbaziants, Igor Bilenko +1 more·Nov 15, 2025

High-Q optical microresonators combine low losses and high optical energy concentration in a small effective mode volume, making them an attractive platform for optical sensors. While light is confined in the microresonator by total internal reflecti...

Hybrid Predictive Quantum Feedback: Extending Qubit Lifetimes Beyond the Wiseman-Milburn Limit

Ali Abu-Nada, Aryan Iliat, Russell Ceballos·Nov 15, 2025

Amplitude damping fundamentally limits qubit lifetimes by irreversibly leaking energy and information into the environment. Standard Wiseman--Milburn feedback offers only modest improvement because it acts on a single measured quadrature and its corr...
