Coherence and contextuality as quantum resources
Rafael Wagner·Nov 20, 2025
In this thesis, we explore the intersection of two fundamental subfields of quantum information theory: quantum coherence and contextuality. Despite their apparent differences, both areas address key issues relevant to the foundations and application...
Efficiently learning non-Markovian noise in many-body quantum simulators
Jordi A. Montañà-López, Andreas Elben, Joonhee Choi +1 more·Nov 20, 2025
As quantum simulators are scaled up to larger system sizes and lower noise rates, non-Markovian noise channels are expected to become dominant. While provably efficient protocols for Markovian models of quantum simulators, either closed system models...
Excited states from local effective Hamiltonians of matrix product states and their entanglement spectrum transition
Denise Cocchiarella, Mingru Yang, Yueshui Zhang +3 more·Nov 20, 2025
Solving excited states is a challenging task for interacting systems. For one-dimensional critical systems, however, excited states can be directly accessed from the eigenvectors of the local effective Hamiltonian that is constructed from the ground ...
White Paper on Quantum Internet Computer Science Research Challenges
Thomas R. Beauchamp, Scarlett Gauthier, Stephanie Wehner·Nov 20, 2025
The aim of a quantum network is to enable the generation of end-to-end entangled links between end nodes of the network, so that they can execute quantum network applications. To facilitate this, it is desirable to have robust control of the network ...
Liouvillian topology and non-reciprocal dynamics in open Floquet chains
Florian Koch, Yu-Min Hu, Jan Carl Budich·Nov 20, 2025
Open quantum systems far from thermal equilibrium can exhibit remarkable physical phenomena including topological properties without a direct equilibrium counterpart. Along these lines, in periodically driven dissipative systems within the effective ...
Conserved quantities enable the quantum Mpemba effect in weakly open systems
Iris Ulčakar, Rustem Sharipov, Gianluca Lagnese +1 more·Nov 20, 2025
Observation of the quantum Mpemba effect has spurred much interest in its enabling conditions and its relation to the classical counterpart. Here, we consider weakly open many-body quantum systems initialized in different thermal states and examine w...
Scalable Quantum Computational Science: A Perspective from Block-Encodings and Polynomial Transformations
Kevin J. Joven, Elin Ranjan Das, Joel Bierman +3 more·Nov 20, 2025
Significant developments made in quantum hardware and error correction recently have been driving quantum computing towards practical utility. However, gaps remain between abstract quantum algorithmic development and practical applications in computa...
Unitary synthesis with optimal brick wall circuits
David Wierichs, Korbinian Kottmann, Nathan Killoran·Nov 20, 2025
We present quantum circuits with a brick wall structure using the optimal number of parameters and two-qubit gates to parametrize $SU(2^n)$, and provide evidence that these circuits are universal for $n\leq 5$. For this, we successfully compile rando...
Hybrid-spin decoupling for noise-resilient DC quantum sensing
So Chigusa, Masashi Hazumi, Ernst David Herbschleb +3 more·Nov 20, 2025
The excellent sensitivities of quantum sensors are a double-edged sword: minuscule quantities can be observed, but any undesired signal acts as noise. This is challenging when detecting quantities that are obscured by such noise. Decoupling sequences...
Adiabatic reverse annealing is robust to low-temperature decoherence
An Le, Christopher L. Baldwin·Nov 20, 2025
Adiabatic reverse annealing (ARA) is an improvement to conventional quantum annealing (QA) that uses an initial guess at the desired ground state to circumvent problematic phase transitions. Despite encouraging results in the closed-system setting, R...
Magnetically induced Josephson nano-diodes in field-resilient superconducting microwave circuits
Benedikt Wilde, Mohamad Kazouini, Timo Kern +5 more·Nov 20, 2025
The development of nonlinear and frequency-tunable superconducting microwave circuits for operation in large magnetic fields is of high relevance for hybrid quantum systems such as spin resonance spectrometers, microwave quantum magnonics, dark matte...
Time Evolution of Multi-Party Entanglement Signals
Vijay Balasubramanian, Hanzhi Jiang, Simon F. Ross·Nov 20, 2025
We study the real-time dynamics of multi-party entanglement signals in chaotic quantum many-body systems including but not necessarily restricted to holographic conformal field theories. We find that scrambling dynamics generates multiparty entanglem...
Navigating the Quantum Resource Landscape of Entropy Vector Space Using Machine Learning and Optimization
Nothando Khumalo, Aman Mehta, William Munizzi +1 more·Nov 20, 2025
We present a machine learning framework to study the dynamics of entropy vectors and quantum resources, including entanglement and magic, focusing on violations of entropy inequalities. Using a reinforcement learning agent formulated as a Markov deci...
Quasiparticle Variational Quantum Eigensolver
Saavanth Velury, Yuxuan Wang·Nov 20, 2025
We propose a momentum-space based variational quantum eigensolver (VQE) framework for simulating quasiparticle excitations in interacting quantum many-body systems on near-term quantum devices. Leveraging translational invariance and other symmetries...
Measurement incompatibility in Bayesian multiparameter quantum estimation
Francesco Albarelli, Dominic Branford, Jesús Rubio·Nov 20, 2025
We present a comprehensive and pedagogical formulation of Bayesian multiparameter quantum estimation, providing explicit conditions for achieving minimum quadratic losses. Within this framework, we analyse the role of measurement incompatibility and ...
Non-Abelian operator size distribution in charge-conserving many-body systems
Mina Tarakemeh, Shenglong Xu·Nov 20, 2025
We show that operator dynamics in U(1) symmetric systems are constrained by two independent conserved charges and construct a non-Abelian operator size basis that respects both, enabling a symmetry-resolved characterization of operator growth. The no...
Correction of chain losses in trapped ion quantum computers
Nolan J. Coble, Min Ye, Nicolas Delfosse·Nov 20, 2025
Neutral atom quantum computers and to a lesser extent trapped ions may suffer from atom loss. In this work, we investigate the impact of atom loss in long chains of trapped ions. Even though this is a relatively rare event, ion loss in long chains mu...

Ivana Nikoloska, Osvaldo Simeone·Nov 20, 2025
The integration of sensing and communication functionalities within a common system is one of the main innovation drivers for next-generation networks. In this paper, we introduce a quantum integrated sensing and communication (QISAC) protocol that l...

Gerónimo J. Caselli, Luis O. Manuel, Liliana Arrachea·Nov 20, 2025
We present a detailed analysis of slowly driven quantum thermal machines based on interacting qubits within the framework of the Lindblad master equation. By implementing a systematic expansion in the driving rate, we derive explicit expressions for ...
OpenQudit: Extensible and Accelerated Numerical Quantum Compilation via a JIT-Compiled DSL
Ed Younis·Nov 20, 2025
High-performance numerical quantum compilers rely on classical optimization, but are limited by slow numerical evaluations and a design that makes extending them with new instructions a difficult, error-prone task for domain experts. This paper intro...
