Introducing Quantum Computing into Statistical Physics: Random Walks and the Ising Model with Qiskit

Zihan Li, Dan A. Mazilu, Irina Mazilu·Nov 5, 2025

Quantum computing offers a powerful new perspective on probabilistic and collective behaviors traditionally taught in statistical physics. This paper presents two classroom-ready modules that integrate quantum computing into the undergraduate curricu...

Realization of a Quantum Streaming Algorithm on Long-lived Trapped-ion Qubits

Pradeep Niroula, Shouvanik Chakrabarti, Steven Kordonowy +30 more·Nov 5, 2025

Large classical datasets are often processed in the streaming model, with data arriving one item at a time. In this model, quantum algorithms have been shown to offer an unconditional exponential advantage in space. However, experimentally implementi...

Frequency shifts heralding ground state squeezing and entanglement of two coupled harmonic oscillators

Safoura Mirkhalaf, Helmut Ritsch, Karol Gietka·Nov 5, 2025

It is often argued that two linearly coupled quantum harmonic oscillators, even when cooled to their ground state, display no inherently quantum features beyond quantized energy levels. Here, we challenge this view by showing that their classical obs...

Certified randomness amplification by dynamically probing remote random quantum states

Minzhao Liu, Pradeep Niroula, Matthew DeCross +49 more·Nov 5, 2025

Cryptography depends on truly unpredictable numbers, but physical sources emit biased or correlated bits. Quantum mechanics enables the amplification of imperfect randomness into nearly perfect randomness, but prior demonstrations have required physi...

Correlation-Powered Work: Equivalence in Peak Yield, Differences in Robustness

Karl Svozil·Nov 5, 2025

Initial system-environment correlations are a thermodynamic resource, enabling work extraction via their erasure. We compare the work potential of classical, quantum, and hypothetical stronger-than-quantum correlations as a function of measurement mi...

Annual-modulation fingerprint of the axion wind induced sideband triplet in quantum dot spin qubit sensors

Xiangjun Tan, Zhanning Wang·Nov 5, 2025

We propose a phase-coherent, narrowband magnetometer for searching couplings between axions or axion-like particles (ALPs) and electron spins, using gate-defined silicon quantum-dot spin qubits. With repeated Ramsey echo sequences and dispersive read...

Directional quantum walks of two bosons on the Hatano-Nelson lattice

Sk Anisur, Kartik Singh, Sayan Choudhury·Nov 5, 2025

We theoretically investigate the interplay of interactions and non-Hermiticity in the dynamics of two bosons on the one-dimensional Hatano-Nelson lattice with non-reciprocal tunneling. We find that the non-reciprocity in the tunneling leads to the fo...

Stability of the Quantum Coherent Superradiant States in Relation to Exciton-Phonon Interactions and the Fundamental Soliton in Hybrid Perovskites

A. A. Gladkij, N. A. Veretenov, N. N. Rosanov +3 more·Nov 5, 2025

The use of macroscopic coherent quantum states at room temperature is crucial in modern quantum technologies. In light of recent experiments demonstrating high-temperature superfluorescence in hybrid perovskite thin films, in this work we investigate...

Spontaneous symmetry breaking in nonlinear superradiance

Nikolai D. Klimkin, Misha Ivanov·Nov 5, 2025

Creation and manipulation of non-classical states of light is rapidly becoming the focus of modern attosecond science. Here, we demonstrate numerically how such states can arise by considering a modification of the well-known problem of superradiance...

Encoding electronic ground-state information with variational even-tempered basis sets

Weishi Wang, Casey Dowdle, James D. Whitfield·Nov 5, 2025

We propose a system-oriented basis-set design based on even-tempered basis functions to variationally encode electronic ground-state information into molecular orbitals. First, we introduce a reduced formalism of concentric even-tempered orbitals tha...

Atom-Field Non-Markovian Dynamics in Open and Dissipative Systems: An Efficient Memory-Kernel Approach Linked to Dyadic Greens Function and CEM Treatments

Hyunwoo Choi, Jisang Seo, Weng C. Chew +1 more·Nov 5, 2025

In this work, we present a numerical framework for modeling single photon emission from a two level system in open and dissipative systems beyond the Markovian approximation. The method can be readily integrated into standard computational electromag...

Quantum error mitigation using energy sampling and extrapolation enhanced Clifford data regression

Zhongqi Zhao, Erik Rosendahl Kjellgren, Sonia Coriani +3 more·Nov 5, 2025

Error mitigation is essential for the practical implementation of quantum algorithms on noisy intermediate-scale quantum (NISQ) devices. This work explores and extends Clifford Data Regression (CDR) to mitigate noise in quantum chemistry simulations ...

The Converse Madelung Question

Jonathan R Dunkley·Nov 5, 2025

We pose the converse Madelung question: not whether Fisher information can reproduce quantum mechanics, but whether it is necessary. We work with minimal, physically motivated axioms on density and phase: locality, probability conservation, Euclidean...

Mutually Unbiased Bases and Orthogonal Latin Squares -- version 3

Stefan Joka·Nov 5, 2025

In this paper, we prove that the existence of a complete set of mutually unbiased bases (MUBs) in N-dimensional Hilbert space implies the existence of a complete set of mutually orthogonal Latin squares (MOLSs) of order N. In particular, we prove tha...

Quantum effects in the magnon spectrum of 2D altermagnets via continuous similarity transformations

Raymond Wiedmann, Dag-Björn Hering, Vanessa Sulaiman +3 more·Nov 5, 2025

We investigate quantum effects on magnon excitations in a minimal spin-1/2 Heisenberg model for 2D altermagnets on the square lattice. A continuous similarity transformation is applied in momentum space to derive an effective Hamiltonian that conserv...

Inertial Repulsion from Quantum Geometry

Maike Fahrensohn, R. Matthias Geilhufe·Nov 5, 2025

We derive a repulsive, charge-dipole-like interaction for a Dirac particle in a rotating frame, arising from a geometric $U(1)$ gauge symmetry associated with the Berry phase. The Lagrangian of this system includes a non-inertial correction due to ce...

We establish the integrability of a family of Sachdev-Ye-Kitaev (SYK) models with uniform $p$-body interactions. We derive the R-matrix and mutually commuting transfer matrices that generate the Hamiltonians of these models, and obtain their exact ei...
