Noise-Induced Equalization in quantum learning models
Francesco Scala, Giacomo Guarnieri, Aurelien Lucchi·Nov 12, 2025
Quantum noise is known to strongly affect quantum computation, thus potentially limiting the performance of currently available quantum processing units. Even learning models based on variational quantum algorithms, which were designed to cope with t...
Efficient and Noise-Resilient Molecular Quantum Simulation with the Generalized Superfast Encoding
James Brown, Tarini S Hardikar, Kenny Heitritter +1 more·Nov 12, 2025
Simulating molecular systems on quantum computers requires efficient mappings from Fermionic operators to qubit operators. Traditional mappings such as Jordan-Wigner or Bravyi-Kitaev often produce high-weight Pauli terms, increasing circuit depth and...
Transversal Toffoli-gate in Hybrid-code System
Dawei Jiao, Mahdi Bayanifar, Alexei Ashikhmin +1 more·Nov 12, 2025
We study the transversality of the Toffoli gate in a hybrid-code system that employs two quantum error correction codes with special structure. We find that a system using a triorthogonal code with its paired code supports a fully transversal impleme...
Tensor Network Framework for Forecasting Nonlinear and Chaotic Dynamics
Jia-Bin You, Jian Feng Kong, Jun Ye·Nov 12, 2025
We present a tensor network model (TNM) for forecasting nonlinear and chaotic dynamics, bridging quantum many-body methods with classical complex systems. The TNM leverages hierarchical tensor contractions to encode non-Markovian temporal correlation...
Hybrid Photonic-Quantum Reservoir Computing For Time-Series Prediction
Oishik Kar, Aswath Babu H·Nov 12, 2025
Motivated by the perspective of advanced time-series prediction and exploitation of Quantum Reservoir Computing (QRC), we explored the design and implementation of a Hybrid Photonic-Quantum Reservoir Computing (HPQRC) paradigm. It brings together the...
Introduction to the Modern Theory of Bose-Einstein Condensation, Superfluidity, and Superconductivity
Phil Attard·Nov 12, 2025
The modern theory of Bose-Einstein condensation, superfluidity, and superconductivity is reviewed. The thermodynamic principle for superfluid flow and the equation of motion for condensed bosons are given. Computer simulations of Lennard-Jones $^4$He...
Complex Eigenvalues in a pseudo-Hermitian \b{eta}-Laguerre ensemble
Cleverson Andrade Goulart, Gleb Oshanin, Mauricio Porto Pato·Nov 12, 2025
Non-Hermitian PT-symmetric models have been extensively studied in recent years. Following the seminal work that reduced classical random matrix ensembles to a tridiagonal form, several efforts have aimed to generalize this framework to non-Hermitian...
Hybrid Atomistic-Parametric Decoherence Model for Molecular Spin Qubits
Katy Aruachan, Sanoj Raj, Yamil J. Colón +2 more·Nov 11, 2025
Solid-state molecular qubits with open-shell ground states have great potential for addressability, scalability, and tunability, but understanding the fundamental limits of quantum coherence in these systems is challenging due to the complexity of th...
Experimental Realization of Thermal Reservoirs with Tunable Temperature in a Trapped-Ion Spin-Boson Simulator
Visal So, Mingjian Zhu, Midhuna Duraisamy Suganthi +5 more·Nov 11, 2025
We propose and demonstrate an experimental scheme to engineer thermal baths with independently tunable temperatures and dissipation rates for the motional modes of a trapped-ion system. This approach enables robust thermal-state preparation and quant...
The FLuid Allocation of Surface code Qubits (FLASQ) cost model for early fault-tolerant quantum algorithms
William J. Huggins, Tanuj Khattar, Amanda Xu +6 more·Nov 11, 2025
Holistic resource estimates are essential for guiding the development of fault-tolerant quantum algorithms and the computers they will run on. This is particularly true when we focus on highly-constrained early fault-tolerant devices. Many attempts t...

Hybrid Quantum Classical (HQC) algorithms constitute one of the most effective paradigms for exploiting the computational advantages of quantum systems in large-scale numerical tasks. By operating in high-dimensional Hilbert spaces, quantum circuits ...
Quantum annealing for lattice models with competing long-range interactions
Jan Alexander Koziol, Kai Phillip Schmidt·Nov 11, 2025
We use superconducting qubit quantum annealing devices to determine the ground state of Ising models with algebraically decaying competing long-range interactions in the thermodynamic limit. This is enabled by a unit-cell-based optimization scheme, i...
