On the temperature of the quantum black hole
Abram Akal·Jan 5, 2026
A nontrivial peculiarity of general relativity is that when the horizon region of black holes is rendered harmless, the exterior doubles, resulting in a causally disconnected parallel universe. This intricacy plays a central role in 't Hooft's unitar...
Binarisation-loophole-free observation of high-dimensional quantum nonlocality
Jia-le Miao, Elna Svegborn, Zhuo Chen +7 more·Jan 5, 2026
Bell inequality tests based on high-dimensional entanglement usually require measurements that can resolve multiple possible outcomes. However, the implementation of high-dimensional multi-outcome measurements is often only emulated via a collection ...
A Length-Gauge Origin-Invariant Approach to Vibrational Circular Dichroism Spectra without Gauge-Including Atomic Orbitals
Brendan M. Shumberger, James R. Cheeseman, Marco Caricato +1 more·Jan 5, 2026
We have extended the origin-invariant length gauge (LG(OI)) approach -- originally developed by Caricato and co-workers for optical rotation (OR) and electronic circular dichroism (ECD) -- to vibrational circular dichroism (VCD). This approach avoids...
Mechanisms and Opportunities for Tunable High-Purity Single Photon Emitters: A Review of Hybrid Perovskites and Prospects for Bright Squeezed Vacuum
Galy Yang, Eric Ashallay, Zhiming Wang +2 more·Jan 5, 2026
Single-photon emitters (SPEs) are central to quantum communication, computing, and metrology, yet their development remains constrained by trade-offs in purity, indistinguishability, and tunability. This review presents a mechanism-based classificati...
Schwarz maps with symmetry
Alfonso García-Velo, Alberto Ibort·Jan 5, 2026
The theory of symmetry of quantum mechanical systems is applied to study the structure and properties of several classes of relevant maps in quantum information theory: CPTP, PPT and Schwarz maps. First, we develop the general structure that equivari...
Modeling Inter-drone Interference as a Service in Skyway Networks
Gabriel Timothy, Syeda Amna Rizvi, Muhammad Umair +2 more·Jan 5, 2026
We present a novel investigation into the impact of inter-drone interference on delivery efficiencies within multi-drone skyway networks. We conduct controlled experiments to analyze the behavior of drones in an indoor testbed environment. Our study ...
Exact Mobility Edges in a Disorder-Free Dimerized Stark Lattice with Effective Unbounded Hopping
Yunyao Qi, Heng Lin, Quanfeng Lu +2 more·Jan 5, 2026
We propose a disorder-free one-dimensional single-particle Hamiltonian hosting an exact mobility edge (ME), placing the system outside the assumptions of no-go theorems regarding unbounded potentials. By applying a linear Stark potential selectively ...
Topological Obstructions for Quantum Adiabatic Algorithms: Evidence from MaxCut Instances
Prathamesh S. Joshi·Jan 5, 2026
Quantum adiabatic algorithms are commonly analyzed through local spectral properties of an interpolating Hamiltonian, most notably the minimum energy gap. While this perspective captures an important constraint on adiabatic runtimes, it does not full...
A General Class of Functionals for Certifying Quantum Incompatibility
Kuan-Yi Lee, Jhen-Dong Lin, Adam Miranowicz +1 more·Jan 5, 2026
Quantum steering, measurement incompatibility, and instrument incompatibility have recently been recognized as unified manifestations of quantum incompatibility. Building on this perspective, we develop a general framework for constructing optimizati...
Quantum AI for Cybersecurity: A hybrid Quantum-Classical models for attack path analysis
Jessica A. Sciammarelli, Waqas Ahmed·Jan 5, 2026
Modern cyberattacks are increasingly complex, posing significant challenges to classical machine learning methods, particularly when labeled data is limited and feature interactions are highly non-linear. In this study we investigates the potential o...
PauliEngine: High-Performant Symbolic Arithmetic for Quantum Operations
Leon Müller, Adelina Bärligea, Alexander Knapp +1 more·Jan 5, 2026
Quantum computation is inherently hybrid, and fast classical manipulation of qubit operators is necessary to ensure scalability in quantum software. We introduce PauliEngine, a high-performance C++ framework that provides efficient primitives for Pau...
Impact of Spatial Proximity on Drone Services
Vejaykarthy Srithar, Syeda Amna Rizvi, Amani Abusafia +2 more·Jan 5, 2026
We demonstrate the peer-to-peer impact of drones flying in close proximity. Understanding these impacts is crucial for planning efficient drone delivery services. In this regard, we conducted a set of experiments using drones at varying positions in ...
Topological States Enabled by Non-local Nonlinearity in Synthetic Dimensions
Chong-Xiao Chen, Zheng-Wei Zhou, Han Pu +1 more·Jan 5, 2026
The interplay between topology and nonlinearity represents a central challenge in modern physics. Here, we investigate this interplay by considering a synthetic Su-Schrieffer-Heeger lattice with all-to-all nonlocal interactions. We find that the dist...
Developments in superconducting erasure qubits for hardware-efficient quantum error correction
Maria Violaris, Luciana Henaut, James Wills +3 more·Jan 5, 2026
Quantum computers are inherently noisy, and a crucial challenge for achieving large-scale, fault-tolerant quantum computing is to implement quantum error correction. A promising direction that has made rapid recent progress is to design hardware that...

Meng Xu, Vasilii Vadimov, J. T. Stockburger +1 more·Jan 5, 2026
Recent advances in quantum technologies and related experiments have created a need for highly accurate, versatile, and computationally efficient simulation techniques for the dynamics of open quantum systems. Long-lived correlation effects (non-Mark...
Optical nonlinearity of cold atomic ensemble driven by strong coherent field in a saturation regime

Quantum machine learning (QML) is expected to offer new opportunities to process high-dimensional data efficiently by exploiting the exponentially large state space of quantum systems. In this work, we apply quantum extreme reservoir computing (QERC)...
O Nature, Where Art Thou?
Fay Dowker·Jan 5, 2026
Where does what happens happen in a quantum system? The standard textbook formulation of quantum mechanics provides a strange, imprecise and yet successful-in-practice answer to this question. In the struggle to unify our understanding of gravity wit...
