Symplectic split-operator method for the time-dependent unitary Tavis-Cummings model
Roman Ovsiannikov, Kurt Jacobs, Andrii G. Sotnikov +1
We present a fast, memory-efficient, unitarity-preserving numerical method beyond the rotating-wave approximation for the closed Tavis-Cummings model in which a multilevel spin sys…
Thermodynamic significance of QUBO encoding on quantum annealers
Emery Doucet, Zakaria Mzaouali, Reece Robertson +3
Quadratic unconstrained binary optimization (QUBO) is the standard interface to quantum annealers, yet a single constrained task admits many QUBO encodings whose penalty choices re…
Quantum Entanglement, Stratified Spaces, and Topological Matter: Towards Entanglement-Sensitive Langlands Data
Kazuki Ikeda, Steven Rayan
Using the spinless Haldane model, we study the witness-filtered Berry curvature, quantum geometric tensor, and quantum Fisher information on the gapped strata of the parameter spac…
Context-Dependent Time-Energy Uncertainty Relations from Projective Quantum Measurements
Mathieu Beau
We introduce a general framework for defining context-dependent time distributions in quantum systems using projective measurements. The time-of-flow (TF) distribution, derived fro…
Quantum Key Distribution by Quantum Energy Teleportation
Shlomi Dolev, Kazuki Ikeda, Yaron Oz
Quantum energy teleportation (QET) is a process that leverages quantum entanglement and local operations to transfer energy between two spatially separated locations without physic…
Time-of-Flow Distributions in Discrete Quantum Systems: From Operational Protocols to Quantum Speed Limits
Mathieu Beau
We propose a general and experimentally accessible framework to quantify transition timing in discrete quantum systems via the time-of-flow (TF) distribution. Defined from the rate…
End-to-End Portfolio Optimization with Quantum Annealing
Sai Nandan Morapakula, Sangram Deshpande, Rakesh Yata +3
Hybrid-quantum classical optimization has emerged as a promising direction for addressing financial decision problems under current quantum hardware constraints. In this work we pr…
No-go theorem for environment-assisted invariance in non-unitary dynamics
Akira Sone, Akram Touil, Kenji Maeda +2
We elucidate the requirements for quantum operations that achieve environment-assisted invariance (envariance), a symmetry of entanglement. While envariance has traditionally been…
Quantum arrival times in free fall
Mathieu Beau, Timothey Szczepanski, Rafael Martellini +1
The probability distribution of a time measurement at position can be inferred from the probability distribution of a position measurement at time as given by t…
Delta-Kick Collimation of Heteronuclear Feshbach Molecules
Timothé Estrampes, José P. D'Incao, Jason R. Williams +4
We present a theoretical study of delta-kick collimation (DKC) applied to heteronuclear Feshbach molecules, focusing on both condensed and thermal ensembles across various interact…
Cavity-enhanced solid-state nuclear spin gyroscope
Hanfeng Wang, Shuang Wu, Kurt Jacobs +3
Solid-state quantum sensors based on ensembles of nitrogen-vacancy (NV) centers in diamond have emerged as powerful tools for precise sensing applications. Nuclear spin sensors are…
Universal distributed blind quantum computing with solid-state qubits
Yan-Cheng Wei, Pieter-Jan Stas, Aziza Suleymanzade +16
Blind quantum computing (BQC) is a promising application of distributed quantum systems, where a client can perform computations on a remote server without revealing any details of…
Concurrence-Driven Path Entanglement in Phase-Modified Interferometry
H. O. Cildiroglu
In this study, a novel experimental setup analogous to joint spin/polarization measurement experiments is proposed by establishing a direct relationship between path (momentum) ent…
Cloning Games, Black Holes and Cryptography
Alexander Poremba, Seyoon Ragavan, Vinod Vaikuntanathan
In this work, we introduce a new toolkit for analyzing cloning games, a notion that captures stronger and more quantitative versions of the celebrated quantum no-cloning theorem. T…

Quantum batteries are anticipated to achieve significant advancements in energy storage capacity. In classical batteries, the energy density at each subsystem reaches its maximum v…
Room-temperature photonic quantum computing in integrated silicon photonics with germanium-silicon single-photon avalanche diodes
Neil Na, Chou-Yun Hsu, Erik Chen +1
Most, if not all, photonic quantum computing (PQC) relies upon superconducting nanowire single-photon detectors (SNSPDs) based on niobium (Nb) operated at a temperature < 4 K. This…
Achieving quantum advantage in a search for a violations of the Goldbach conjecture, with driven atoms in tailored potentials
Oleksandr V. Marchukov, Andrea Trombettoni, Giuseppe Mussardo +1
The famous Goldbach conjecture states that any even natural number greater than can be written as the sum of two prime numbers and . In th…
Bulk and boundary entanglement transitions in the projective gauge-Higgs model
Hiroki Sukeno, Kazuki Ikeda, Tzu-Chieh Wei
In quantum many-body spin systems, the interplay between the entangling effect of multi-qubit Pauli measurements and the disentangling effect of single-qubit Pauli measurements may…

Motivated by the great success of classical generative models in machine learning, enthusiastic exploration of their quantum version has recently started. To depart on this journey…
Pseudomagic Quantum States
Andi Gu, Lorenzo Leone, Soumik Ghosh +3
Notions of nonstabilizerness, or "magic", quantify how non-classical quantum states are in a precise sense: states exhibiting low nonstabilizerness preclude quantum advantage. We i…
