Variance reduction for forces and pressure in variational Monte Carlo
David Linteau, Saverio Moroni, Giuseppe Carleo +1 more·Mar 15, 2026
We present simple and practical strategies to reduce the variance of Monte Carlo estimators. Our focus is on variational Monte Carlo calculations of atomic forces and pressure in electronic systems, although we show that the underlying ideas apply mo...
Excited Pfaffians: Generalized Neural Wave Functions Across Structure and State
Nicholas Gao, Till Grutschus, Frank Noé +1 more·Mar 15, 2026
Neural-network wave functions in Variational Monte Carlo (VMC) have achieved great success in accurately representing both ground and excited states. However, achieving sufficient numerical accuracy in state overlaps requires increasing the number of...
Quantum Enhanced Pauli Propagation
S. Majumder, J. R. Garrison, L. Luo +8 more·Mar 15, 2026
Accurately estimating observables on noisy quantum devices remains a central challenge for near-term quantum algorithms. While quantum error mitigation techniques can reduce noise-induced bias, they often rely on unverifiable assumptions about the ci...
The Twin-World road to reality in quantum mechanics
Daniel Braun·Mar 15, 2026
I introduce a novel realistic, stochastic approach to quantum mechanics by extending the recently proposed grabit formalism \cite{braun_stochastic_2022} to two Twin Worlds. According to the picture developed, we live at the intersection of two worlds...
Quantum-limited traveling-wave parametric amplifier based on DUV lithography-defined planar structures
Hao Li, Marco Scigliuzzo, Evgenii Guzovskii +3 more·Mar 15, 2026
The relentless scaling of classical microelectronics has been enabled by the precision and reproducibility of deep-ultraviolet (DUV) optical lithography. Implementing large-scale superconducting quantum processors will require cryogenic microwave com...
How to find expressible and trainable parameterized quantum circuits?
Peter Röseler, Dennis Willsch, Kristel Michielsen·Mar 15, 2026
Whether parameterized quantum circuits (PQCs) can be systematically constructed to be both trainable and expressive remains an open question. Highly expressive PQCs often exhibit barren plateaus, while several trainable alternatives admit efficient c...
Disentangling Tensor Network States with Deep Neural Network
Chaohui Fan, Bo Zhan, Yuntian Gu +5 more·Mar 15, 2026
We introduce Neural Tensor Network States ($ν$TNS), a variational many-body wave-function ansatz that integrates deep neural networks with tensor-network architectures. In the $ν$TNS framework, a neural network serves as a disentangler of the wave-fu...
Non-Resonant Boundary Time Crystals from Quantum Synchronization Breakdown
Jun Wang, Shu Yang, Zeqing Wang +4 more·Mar 15, 2026
Quantum synchronization (QS) in dissipative systems is often inferred from smooth phase locking, leaving open whether its breakdown constitutes a genuine nonequilibrium transition. Here we introduce a Liouvillian framework that classifies driven-diss...
Mixed-State Entanglement in a Minimal Model of Quantum Chaos
Tanay Pathak·Mar 15, 2026
Understanding the dynamics of quantum correlations in many-body systems is a central problem in non-equilibrium quantum physics. We study the spread of mixed-state entanglement in a minimal model of quantum chaos, the kicked field Ising model. By com...
Phase-preserving control of Floquet-engineered cavity quantum electrodynamics
J. W. Yu, X. Q. Zhou, Z. B. Ni +6 more·Mar 15, 2026
We propose a Floquet-engineered framework for the coherent control of the light-matter interaction in a two-level system (TLS) located in a time-modulated cavity. Strictly phase-preserving operation of the TLS-cavity interaction is demonstrated, allo...
On aggregation-quantization permutability problem for discrete-time Markov chains
Adam Doliwa, Artur Siemaszko, Adam Zalewski·Mar 15, 2026
Given random walk on a graph, the corresponding discrete-time quantum walk can be constructed using the method proposed by Szegedy. On the other hand, given a partition of the set of states of a Markov chain, one can study the corresponding aggregate...
Multi-qubit controlled gate with optimal T-count
Soichiro Yamazaki, Seiseki Akibue·Mar 15, 2026
Controlled gates are key components in various quantum algorithms. Improving on the prior work of Gosset et al., we show that, for an allowed error $\varepsilon$, $3\log_2(1/\varepsilon) + o(\log(1/\varepsilon))$ $T$ gates are sufficient to approxima...
Frequency-resolved N-photon correlations in the ultra-strong coupling regime
Wen Huang, Qian Bin, Ying Wu +1 more·Mar 15, 2026
Frequency-resolved photon emission is central to applications from quantum information encoding to high-resolution spectroscopy, and then studying their correlations is therefore essential for revealing the underlying emission pathways and multiphoto...
Emergent giant topological Hall effect in twisted Fe3GeTe2 metallic system
Hyuncheol Kim, Kai-Xuan Zhang, Yu-Hang Li +3 more·Mar 15, 2026
The topological Hall effect, driven by the exchange interaction between conduction electrons and topological magnetic textures such as skyrmions, is a powerful probe for investigating the topological properties of magnetic materials. Typically, this ...
