Quantum-classical hybrid models based on error correction for time series forecasting
Jonathan H. A. de Carvalho, Filipe C. de L. Duarte, Fernando M. de Paula Neto +1 more·Jun 13, 2026
Time series forecasting largely benefits from combining the strengths of different models, especially using a scheme where a model corrects another model by capturing supplementary patterns from forecasting errors. Concurrently, quantum models are pr...
Lattice surgery for near-term experimental logical qubit entanglement creation in planar architectures
Lukas Bödeker, Áron Márton, Luis Colmenarez +3 more·Jun 13, 2026
In the era of early fault-tolerant quantum computing, basic demonstrations of entanglement operations between a few logical qubits are at the frontier of recent developments in quantum computing. In this work, we describe in detail, at both the logic...
Interaction-enabled topological pumping of Rydberg electrons
Chenxi Huang, Tao Chen, Kaden R. A. Hazzard +2 more·Jun 13, 2026
Topological pumping is a paradigmatic realization of quantized transport in band systems, yet its fate in strongly correlated regimes, especially with long-range interactions, remains largely unexplored. Here we report the experimental observation of...
Programmable Gauge-Field Textures with Ultracold Atoms in Momentum Space
Hongru Wang, Hang Li, Yichen Pan +4 more·Jun 13, 2026
Synthetic gauge fields with ultracold atoms offer a route to quantum matter in which electromagnetic environments can be designed rather than merely imposed. While the Harper-Hofstadter model has been realized in several cold-atom systems, existing i...
Information Is Not Physical: Possibility Spaces, Erasure, and the Structure of Unrealized Alternatives
Madhurendra Mishra·Jun 13, 2026
The slogan ``information is physical,'' introduced by Rolf Landauer and developed through quantum information theory and black-hole thermodynamics, has achieved near-axiomatic status in modern physics. Yet the ontological status of information remain...
Optimal Toffoli-Depth Multi-Controlled Toffoli Decomposition in 2D Qubit Layout
Anik Basu Bhaumik, Suman Dutta, Anupam Chattopadhyay·Jun 13, 2026
The multi-controlled Toffoli (MCT) gate is a key primitive in quantum arithmetic, oracle construction, and quantum cryptanalysis. Although recent work has established optimal Toffoli-depth MCT decompositions under all-to-all qubit connectivity, their...
Temporal modulation as a resource: enhanced frequency estimation in continuous variable systems
Ningxin Kong, Qiongyi He, Matteo G. A. Paris·Jun 13, 2026
Frequency estimation, a cornerstone of quantum metrology, has been significantly enhanced by advanced quantum sensing strategies. However, most protocols rely either on static or time-independent encoding mechanisms, inherently limiting their achieva...
Optimizing Wigner Negativity in Scattering Processes Using Energetic Cost Functions
Kian Hwee Lim, Kiarn T. Laverick, Sahil Sardar Jafar +3 more·Jun 13, 2026
Wigner negativities (WNs) are key signatures of non-Gaussian bosonic states and essential resources for quantum technologies. We study their generation in the scattering of coherent pulses by a two-level atom coupled to a one-dimensional reservoir, a...
REGRID-QAOA: A Resource-Efficient Hybrid QAOA Framework for Physics-Constrained Power System Islanding
Yuqi Jiang, Yuqi Zhang, Zhiding Liang +3 more·Jun 13, 2026
Quantum computing has rapidly emerged as a powerful paradigm for tackling computationally demanding problems. In particular, quantum optimization shows strong promise for hard combinatorial problems in power systems, where increasing distributed ener...
Quantum learning with a single-atom sensor
Yin Mo, Emilio Bagan, Giulio Chiribella·Jun 13, 2026
The ability to gather information and to act upon it is at the core of every learning agent. But what is the impact of quantum mechanics on an agent's ability to sense external inputs and to translate them into actions? Here we address the question f...
Quantum simulation of the Liouville equation in classical mechanics with discontinuous potential via Schrödingerization
Shi Jin, Shuyi Zhang·Jun 13, 2026
We develop quantum simulation algorithms for the Liouville equation of classical mechanics with discontinuous potential. Such discontinuities represent potential barriers at which classical particles undergo energy preserving transmission or reflecti...
Discontinuous strong-to-weak symmetry breaking transition from thermal pure states
Taiki Haga, Masaya Kunimi, Masaya Nakagawa·Jun 13, 2026
We investigate the nonequilibrium dynamics of strong-to-weak spontaneous symmetry breaking in many-body quantum systems undergoing decoherence from thermal pure states. For generic initial pure states with volume-law entanglement entropy, we show tha...
VQE as Initial State Preparation for QPE on Heisenberg Spin-Glass Hamiltonians
Elijah Pelofske, Stephan Eidenbenz·Jun 13, 2026
Quantum Phase Estimation (QPE) is the quantum algorithmic workhorse for computing ground state energies of quantum Hamiltonians with quantum computers. Ground state energy calculation of physical systems is perhaps the most promising use case for qua...
On-Demand Coherent Mapping of Telecom Optical States onto Erbium Hyperfine Spins
Zongfeng Li, Mahdi Hosseini·Jun 12, 2026
Optical quantum memories operating directly at telecom wavelengths are a key enabling technology for long-distance quantum networks, yet on-demand storage onto long-lived ground-state spins in this spectral region has remained elusive due to the chal...
Optical Creation of Synthetic Microgravity for Quantum Degenerate Gases
Catie LeDesma, Kendall Mehling, Tristan Rojo +1 more·Jun 12, 2026
Microgravity environments provide unique opportunities for ultracold-atom experiments by enabling long interrogation times and reduced acceleration-induced dynamics. However, their realization has largely been restricted to specialized facilities suc...
Microscopic exceptional points in the post-selected open Jaynes--Cummings model
B. M. Rodríguez-lara·Jun 12, 2026
Phenomenological non-Hermitian Hamiltonians track selected signatures of complex reservoir dynamics, while post-selected no-jump effective Hamiltonians derived from microscopic open-system theory reveal the underlying system--reservoir physics. We de...
Initiation of Superradiance from Different Collective Spin States
Adnan Alabbar, Zhenghao Zhang, Girish S. Agarwal·Jun 12, 2026
Superradiance is an extensive cooperative spontaneous emission phenomenon. Some atomic collective spin states exhibit it. However, distinct initial states differ in their decay dynamics. Dicke states with different numbers of excitations have their p...

Grier M. Jones, Maforikan J. Amoussou, Maximilian O. Leach +1 more·Jun 12, 2026
In this study, we analyze the choice of local unitary cluster Jastrow (LUCJ) ansatz initialization and sensitivity of the sample-based quantum diagonalization (SQD) algorithm within the quantum-centric supercomputing (QCSC) framework. We examine six ...
Optimising Entanglement Distillation Policies
Jigyen Bhavsar, Rajni Bala, Siddhartha Santra·Jun 12, 2026
Entanglement distillation is a fundamental operation in quantum information processing used to obtain higher-fidelity entangled pairs from a supply of less entangled quantum states using local operations aided by classical communication (LOCC). In a ...
