Hybrid digital-analog protocols for simulating quantum multi-body interactions
Or Katz, Alexander Schuckert, Tianyi Wang +3 more·Dec 24, 2025
While quantum simulators promise to explore quantum many-body physics beyond classical computation, their capabilities are limited by the available native interactions in the hardware. On many platforms, accessible Hamiltonians are largely restricted...
Bose polarons as relativistic Unruh-DeWitt detectors: Entanglement harvesting from Bose-Einstein condensates
T. Rick Perche, Francesco Gozzini, Markus K. Oberthaler·Dec 24, 2025
We show that a bound impurity in a Bose-Einstein condensate can be directly mapped to an Unruh-DeWitt detector interacting with a relativistic quantum field. We provide explicit experimental parameters for an implementation using ${}^{39}\text{K}$ im...
Universality of equilibration dynamics after quantum quenches
Vincenzo Alba, Sanam Azarnia, Gianluca Lagnese +1 more·Dec 24, 2025
We investigate the distribution of the eigenvalues of the reduced density matrix (entanglement spectrum) after a global quantum quench. We show that in an appropriate scaling limit the lower part of the entanglement spectrum exhibits ``universality''...
Optimizing Quantum State Transformation Under Locality Constraint
Sasan Sarbishegi, Maryam Sadat Mirkamali·Dec 24, 2025
In this paper, we present a general numerical framework for both deterministic and probabilistic quantum state transformations, under locality constraints. For a given arbitrary bipartite initial state and a desired bipartite target state, we constru...
A Note on Publicly Verifiable Quantum Money with Low Quantum Computational Resources
Fabrizio Genovese, Lev Stambler·Dec 24, 2025
In this work we present a publicly verifiable quantum money protocol which assumes close to no quantum computational capabilities. We rely on one-time memories which in turn can be built from quantum conjugate coding and hardware-based assumptions. S...
Quantum computation of mass gap in an asymptotically free theory
Paulo F. Bedaque, Edison M. Murairi, Gautam Rupak +1 more·Dec 24, 2025
In relativistic field theories, the mass spectrum is given by the difference between the energy of the vacuum and the excited states. Near the continuum limit, the cancellation between these two values leads to loss of precision. We propose a method ...
Hamilton-Jacobi as model reduction, extension to Newtonian particle mechanics, and a wave mechanical curiosity
Amit Acharya·Dec 24, 2025
The Hamilton-Jacobi equation of classical mechanics is approached as a model reduction of conservative particle mechanics where the velocity degrees-of-freedom are eliminated. This viewpoint allows an extension of the association of the Hamilton-Jaco...
Characterizing quantum synchronization in the van der Pol oscillator via tomogram and photon correlation
Kingshuk Adhikary, K. M. Athira, M. Rohith·Dec 24, 2025
We access the quantum synchronization (QS) in the steady state of a driven quantum van der Pol oscillator (vdPo) using two distinct figures of merit: (i) the nonclassical area $δ$ and (ii) the second-order correlation function $g^{(2)}(0)$, which are...
Observation of the Aharonov-Bohm Effect in Pilot-Wave Hydrodynamics
Georgi Gary Rozenman, Kyle I. McKee, Arnaud Lazarus +2 more·Dec 24, 2025
We report the results of an experimental study of an analog of the Aharonov-Bohm (AB) effect achieved with the hydrodynamic pilot-wave system. A walking droplet is confined to an annular cavity that encircles a shielded vortex, but lies outside its r...
Random dilation superchannel
Satoshi Yoshida, Ryotaro Niwa, Mio Murao·Dec 24, 2025
We present a quantum circuit that implements the random dilation superchannel, transforming parallel queries of an unknown quantum channel into parallel queries of a randomly chosen dilation isometry of the input channel. This is a natural generaliza...
Squeezed quantum multiplets: properties and phase space representation
Juan Pablo Paz, Corina Révora, Christian Tomás Schmiegelow·Dec 24, 2025
We define and study the properties of ``squeezed quantum multiplets''. Ordinary multiplets are sets of $D$-orthonormal quantum states formed by superpositions of states squeezed along $D$ equally spaced directions in quadrature space. More generally,...
Quantum entanglement between partons in a strongly coupled quantum field theory
Wenyu Zhang, Wenyang Qian, Yiyu Zhou +2 more·Dec 24, 2025
We perform a first-principles, non-perturbative investigation of quantum entanglement between partonic constituents in a strongly coupled 3+1-dimensional scalar Yukawa theory, using light-front Hamiltonian methods with controlled Fock-space truncatio...
3D cavity-based graphene superconducting quantum circuits in two-qubit architectures
Kuei-Lin Chiu, Avishma J. Lasrado, Cheng-Han Lo +4 more·Dec 24, 2025
We construct a series of graphene-based superconducting quantum circuits and integrate them into 3D cavities. For a single-qubit device, we demonstrate flux-tunable qubit transition, with a measured $T_1$ $\approx$ 48 ns and a lower bound estimate of...
All-optical control and multiplexed readout of multiple superconducting qubits
Xiaoxuan Pan, Chuanlong Ma, Jia-Qi Wang +12 more·Dec 24, 2025
Superconducting quantum circuits operate at millikelvin temperatures, typically requiring independent microwave cables for each qubit for connecting room-temperature control and readout electronics. However, scaling to large-scale processors hosting ...
Controlling photothermal forces and backaction in nano-optomechanical resonators through strain engineering
Menno H. Jansen, Cauê M. Kersul, Ewold Verhagen·Dec 24, 2025
In micro- and nanoscale optomechanical systems, radiation pressure interactions are often complemented or impeded by photothermal forces arising from thermal strain induced by optical heating. We show that the sign and magnitude of the photothermal f...
Interaction-Resilient Scalable Fluxonium Architecture with All-Microwave Gates
Andrei A. Kugut, Grigoriy S. Mazhorin, Ilya A. Simakov·Dec 24, 2025
Fluxonium qubits demonstrate exceptional potential for quantum processing; yet, realizing scalable architectures using them remains challenging. We propose a fluxonium-based square-grid design with fast $\sim63$~ns controlled-Z (CZ) gates, achieving ...
Quantum Approximate Optimization Algorithm with Fixed Number of Parameters
Sebastián Saavedra-Pino, Ricardo Quispe-Mendizábal, Gabriel Alvarado Barrios +3 more·Dec 24, 2025
We introduce a novel quantum optimization paradigm: the Fixed-Parameter-Count Quantum Approximate Optimization Algorithm (FPC-QAOA). It is a scalable variational framework that maintains a constant number of trainable parameters regardless of the num...
Coupled-wire construction of non-Abelian higher-order topological phases
Jiaxin Pan, Longwen Zhou·Dec 24, 2025
Non-Abelian topological charges (NATCs), characterized by their noncommutative algebra, offer a framework for describing multigap topological phases beyond conventional Abelian invariants. While higher-order topological phases (HOTPs) host boundary s...
Information-Scrambling-Enhanced Quantum Sensing Beyond the Standard Quantum Limit
Yangyang Ge, Haoyu Zhou, Wen Zheng +16 more·Dec 24, 2025
Quantum sensing promises measurement precision beyond classical limits, but its practical realization is often hindered by decoherence and the challenges of generating and stabilizing entanglement in large-scale systems. Here, we experimentally demon...
Bridging Microscopic Constructions and Continuum Topological Field Theory of Three-Dimensional Non-Abelian Topological Order
Yizhou Huang, Zhi-Feng Zhang, Qing-Rui Wang +1 more·Dec 24, 2025
In this paper, we bridge this gap systematically by establishing an explicit correspondence between continuum topological field theory and microscopic lattice constructions of three-dimensional non-Abelian topological orders. While Wilson operators d...
