Quantum, Stochastic, and Classical Dynamics Within A Single Geometric Framework

Partha Ghose·Oct 31, 2025

Nelson's stochastic mechanics links quantum mechanics to an underlying Brownian motion with the identification $\hbar = mσ$. Ghose's interpolating equation introduces a continuous parameter $λ$ that suppresses the quantum potential $Q[ψ]$ and yields ...

Inter-transition interference in spectrum of Kerr parametric oscillators

Shumpei Masuda·Oct 31, 2025

We theoretically investigate reflection and transmission measurements of two-photon and four-photon Kerr parametric oscillators (KPOs), introducing interference effects between inter-level transitions. Due to the level degeneracy of a KPO, a probe fi...

On-chip cavity electro-acoustics using lithium niobate phononic crystal resonators

Jun Ji, Joseph G. Thomas, Zichen Xi +7 more·Oct 31, 2025

Mechanical systems are pivotal in quantum technologies because of their long coherent time and versatile coupling to qubit systems. So far, the coherent and dynamic control of gigahertz-frequency mechanical modes mostly relies on optomechanical coupl...

Dependence-Driven, Scalable Quantum Circuit Mapping with Affine Abstractions

Marouane Benbetka, Merwan Bekkar, Riyadh Baghdadi +1 more·Oct 31, 2025

Qubit Mapping is a critical task in Quantum Compilation, as modern Quantum Processing Units (QPUs) are constrained to nearest-neighbor interactions defined by a qubit coupling graph. This compiler pass repairs the connectivity of two-qubit gates whos...

Magnetic wideband VHF localized field probe using magnon polaritons

G. Soares, N. Crescini, G. Carugno +1 more·Oct 31, 2025

We present here an optimisation and demonstration of a wide band instrument capable of measuring localised and directionally alternated magnetic fields below pT in the very high frequency (VHF) range. We take advantage of the magnon-photon hybridizat...

Fast Bosonic Control via Multiphoton Qubit-Oscillator Interactions

Noah Gorgichuk, Mohammad Ayyash, Matteo Mariantoni +1 more·Oct 30, 2025

We present a protocol for preparing oscillator states with $n$-fold rotational symmetry, which include many logical codewords for bosonic quantum error correction codes. The protocol relies on a multiphoton interaction between the oscillator and an a...

High-Q microresonators unveil quantum rare events

Sricharan Raghavan-Chitra, Arghadip Koner, Joel Yuen-Zhou·Oct 30, 2025

Classical linear optics posits that at sufficiently low intensities, light propagation in dielectric media is governed solely by their linear susceptibilities. Here, we demonstrate a departure from this paradigm in high-Q microresonators, where prolo...

Electron juggling: Approaching the atomic physics limit of the attempt rate in trapped ion photonic interconnects

I. D. Moore, B. M. White, B. Graner +1 more·Oct 30, 2025

Photonic interconnects are a key technology for scaling up atomic based quantum computers. By facilitating the connection of multiple systems, high-performance modular quantum processing units may be constructed to perform deeper and more useful algo...

Sample-Based Krylov Quantum Diagonalization for the Schwinger Model on Trapped-Ion and Superconducting Quantum Processors

Emil Otis Rosanowski, Jurek Eisinger, Lena Funcke +2 more·Oct 30, 2025

We apply the recently proposed Sample-based Krylov Quantum Diagonalization (SKQD) method to lattice gauge theories, using the Schwinger model with a $θ$-term as a benchmark. SKQD approximates the ground state of a Hamiltonian, employing a hybrid quan...

Dirac - von Neumann axioms in the setting of Continuous Model Theory

Boris Zilber·Oct 30, 2025

We recast the well-known axiom system of quantum mechanics used by physicists (the Dirac calculus) in the language of Continuous Logic. For the basic version of the axiomatic system we prove that along with the canonical continuous model the axioms h...

Harnessing Floquet dynamics for selective metrology in few-qubit systems

Asghar Ullah, Hasan Mermer, Melih Özkurt +2 more·Oct 30, 2025

Periodically driven quantum systems can function as highly selective parameter filters. We demonstrate this capability in a finite-size, three-qubit system described by the transverse-field Floquet Ising model. In this system, we identify a period-do...

Anderson localization: A view from Krylov space

J. Clayton Peacock, Vadim Oganesyan, Dries Sels·Oct 30, 2025

The Krylov subspace expansion is a workhorse method for sparse numerics that has been increasingly explored as source of physical insight into many-body dynamics in recent years. In this work we revisit the venerable Anderson model of localization in...

Superdiffusion and anomalous fluctuations in chiral integrable dynamics

Cristiano Muzzi, Devendra Singh Bhakuni, Marcello Dalmonte +2 more·Oct 30, 2025

Symmetries strongly influence transport properties of quantum many-body systems, and can lead to deviations from the generic case of diffusion. In this work, we study the impact of time-reversal symmetry breaking on the transport and its universal as...

Exact and approximate conditions of tabletop reversibility: when is Petz recovery cost-free?

Minjeong Song, Hyukjoon Kwon, Valerio Scarani·Oct 30, 2025

Channels $\mathcal{N}$ that describe open quantum dynamics are inherently irreversible: it is impossible to undo their effect completely, but one can study partial recovery of the information. The Petz recovery map $\hat{\mathcal{N}}_γ^{(\texttt{P})}...
