Second-order discretization of Dyson series: iterative method, numerical analysis and applications in open quantum systems
Zhenning Cai, Yixiao Sun, Geshuo Wang·Oct 17, 2025
We propose a general strategy to discretize the Dyson series without applying direct numerical quadrature to high-dimensional integrals, and extend this framework to open quantum systems. The resulting discretization can also be interpreted as a Stra...
Trust Region Bayesian Optimization of Annealing Schedules on a Quantum Annealer
Seon-Geun Jeong, Mai Dinh Cong, Minh-Duong Nguyen +3 more·Oct 17, 2025
Quantum annealing (QA) is a practical model of adiabatic quantum computation, already realized on hardware and considered promising for combinatorial optimization. However, its performance is critically dependent on the annealing schedule due to hard...
Quantum Voting Protocol for Centralized and Distributed Voting Based on Phase-Flip Counting
Ali Emre Aydin, Ammar Daskin·Oct 17, 2025
We introduce a quantum voting protocol that uses superposition and entanglement to enable secure, anonymous voting in both centralized and distributed settings. Votes are encoded via phase-flip operations on entangled candidate states, controlled by ...
Game-Theoretic Discovery of Quantum Error-Correcting Codes Through Nash Equilibria
Rubén Darío Guerrero·Oct 17, 2025
Quantum error correction code discovery has relied on algebraic constructions with predetermined structure or computational search lacking mechanistic interpretability. We introduce a game-theoretic framework recasting code optimization as strategic ...
Solid-State High-Order Harmonic Generation: Emerging Frontiers in Ultrafast and Quantum Light Science
Marcelo F. Ciappina·Oct 17, 2025
High-order harmonic generation (HHG) in solids has emerged as a versatile platform for exploring ultrafast and quantum-coherent phenomena in condensed matter. Recent advances reveal Berry-phase and topological effects in harmonic emission, strong-fie...
FSRCC two-valence calculations of clock transition properties, dipole polarizability and isotope shifts in Fermionic and Bosonic Sr
Palki Gakkhar, D. Angom, B. Mani·Oct 17, 2025
We employ an all-particle multireference Fock-space relativistic coupled-cluster (FSRCC) theory to study the $5s^2{\;^1}S_0 - 5s5p{\;^3P^o_0}$ clock transition in both Fermionic and Bosonic isotopes of Sr. We compute the excitation energies, E1 and M...
FIDDLE: Reinforcement Learning for Quantum Fidelity Enhancement
Hoang M. Ngo, T.M. Kahveci, My T. Thai·Oct 17, 2025
Quantum computing has the potential to revolutionize fields like quantum optimization and quantum machine learning. However, current quantum devices are hindered by noise, reducing their reliability. A key challenge in gate-based quantum computing is...
Open system dynamics in local Lindbladians with chaotic spectra
Sanket Chirame, Fiona J. Burnell·Oct 16, 2025
We investigate the physical consequences of having a spectrum that satisfies random matrix theory (RMT) for generic Lindbladians, and compare its implications for spatially local and completely random Lindblad dynamics in one spatial dimension. We fi...
Superconducting Gap Engineering in Tantalum-Alloy-Based Resonators
Chen Yang, Faranak Bahrami, Guangming Cheng +7 more·Oct 16, 2025
Utilizing tantalum (Ta) in superconducting circuits has led to significant improvements, such as high qubit lifetimes and quality factors in both qubits and resonators, underscoring the importance of material optimization in quantum device performanc...
Fundamental Limits to Cat-Code Qubits from Chaos-Assisted Tunneling
Lionel E. Martínez, Ignacio García-Mata, Diego A. Wisniacki·Oct 16, 2025
We show that chaos-assisted tunneling (CAT) imposes an intrinsic limit to the protection of Kerr-cat qubits. In the static effective description, tunneling between the quasidegenerate cat states can be exponentially suppressed, ensuring long lifetime...
The Elegant Joint Measurement is Non-Classical in the Triangle Network
Victor Gitton, Renato Renner·Oct 16, 2025
When quantum systems are shared by multiple parties in a network, the measurement outcomes of the parties can exhibit non-classical correlations, i.e., correlations that cannot be obtained if the parties shared classical systems instead. This phenome...
Interrelation of Non-Classicality, Entropy, Irreversibility and Work extraction in Open Quantum Systems
Jai Lalita, Subhashish Banerjee·Oct 16, 2025
The interplay of non-classical volume, von Neumann entropy, entropy production, and ergotropy is investigated in various open quantum systems. Two categories of open quantum system models are utilized: spin-spin and spin-boson interaction models. The...

An algorithm which encodes the $L\times L$ 2D toric code logical state with a circuit of depth $2L+1$, using only local controlled-NOT($CX$) and Hadamard($H$) gates, is presented.
