Observable-Conditioned Backaction in Dynamic Circuits: A Higher-Order Context-Conditioned Kernel for Local Dynamics
Petr Sramek·Mar 19, 2026
Mid-circuit measurements are essential primitives for dynamic circuits and quantum error correction, yet characterizing their induced disturbance on spectator qubits remains a central practical problem. Device-level benchmarking often compresses this...
Black Hole--Entropy Container or Creator
William G Unruh·Mar 19, 2026
Do black holes possess entropy or do they create it? The dominant assumption is that they possess entropy, and a they evaporate that entropy is emitted and decreases. In this paper I use a model of a linear amplifier, in which I argue that the amplif...
Alice and Bob through a quantum mirror
M. Uria, C. Hermann-Avigliano, P. Solano +1 more·Mar 19, 2026
A quantum mirror is a device whose optical response, that is, transmission and reflection, can be controlled by a single qubit. Here, we propose the use of quantum mirrors as nodes in quantum networks. Propagating coherent states mediate the interact...
Benchmarking NIST-Standardised ML-KEM and ML-DSA on ARM Cortex-M0+: Performance, Memory, and Energy on the RP2040
Rojin Chhetri·Mar 19, 2026
The migration to post-quantum cryptography is urgent for Internet of Things devices with 10--20 year lifespans, yet no systematic benchmarks exist for the finalised NIST standards on the most constrained 32-bit processor class. This paper presents th...
Towards Noise-Resilient Quantum Multi-Armed and Stochastic Linear Bandits
Zhuo Chen, Kechao Cai·Mar 19, 2026
Quantum multi-armed bandits (MAB) and stochastic linear bandits (SLB) have recently attracted significant attention, as their quantum counterparts can achieve quadratic speedups over classical MAB and SLB. However, most existing quantum MAB algorithm...
Leveraging Classical and Quantum Computing for Process Systems Engineering Applications: Decomposition Algorithm with Ising Solvers for Efficient Discrete Landscape Exploration
Yirang Park, David E. Bernal Neira·Mar 19, 2026
Conceptual process design is a crucial aspect of chemical engineering that involves process synthesis. Mixed-integer nonlinear programming is a powerful framework for modeling such design problems by combining discrete and continuous variables; howev...
Nonlocal Games as Cross-Platform Quantum Benchmarks: Exceeding unconditional classical bounds on trapped-ion processors
Anton T. Than, Jim Furches, Debopriyo Biswas +15 more·Mar 18, 2026
Nonlocal games provide application-level benchmarks for quantum hardware whose classical performance bounds are information-theoretic, holding against all classical strategies regardless of computational resources. We implement a 14-vertex graph colo...
Efficient Soft-Output Guessing for Enhanced Quantum Tanner Code Decoding
Lukas Rapp, Muriel Médard, Eugene Tang +1 more·Mar 18, 2026
We introduce a generalized low-density parity-check decoding framework for quantum Tanner codes utilizing soft-output guessing random additive noise decoding (SOGRAND). By soft-output decoding entire component codes, we mitigate trapping sets and cyc...
Multi-Outcome Circuit Optimization for Enhanced Non-Gaussian State Generation
S. Ismailzadeh, B. Abedi Ravan·Mar 18, 2026
Photonic quantum computing has gained significant interest in recent years due to its potential for scaling to large numbers of qubits. A critical requirement for fault-tolerant quantum computation is the reliable generation of non-Gaussian quantum s...
Anderson transition in disordered Hatano-Nelson systems
Silvio Barandun·Mar 18, 2026
We illuminate the fundamental mechanism responsible for the transition between the non-Hermitian skin effect and defect-induced Anderson localization in the bulk via the study of Lyapunov exponents. We obtain a proof that the change of the topologica...
Continuous symmetry analysis and systematic identification of candidate order parameters for interacting fermion models
Cheng-Hao He, Yi-Zhuang You, Xiao Yan Xu·Mar 18, 2026
Symmetry plays a central role in modern physics, from classifying quantum states to characterizing phases of matter through spontaneous symmetry breaking. In interacting fermionic systems with multiple internal degrees of freedom, however, determinin...
Iterative Decoding of Stabilizer Codes under Radiation-Induced Correlated Noise
Anuj K. Nayak, Paul G. Baity, Peter J. Love +4 more·Mar 18, 2026
Fault-tolerant quantum computation demands extremely low logical error rates, yet superconducting qubit arrays are subject to radiation-induced correlated noise arising from cosmic-ray muon-generated quasiparticles. The quasiparticle density is unkno...
From Classical Stochastic to Monitored Quantum Dynamics: Dynamical Phase Coexistence in East Circuit Models
Marcel Cech, Johan du Buisson, Cecilia De Fazio +2 more·Mar 18, 2026
Kinetically constrained models have been widely studied in the context of glass formers and non-equilibrium statistical mechanics. Although their simple local rules often result in structureless static properties, their dynamics exhibit intricate eme...
An HHL-Based Quantum-Classical Solver for the Incompressible Navier-Stokes Equations with Approximate QST
Moshe Inger, Steven Frankel·Mar 18, 2026
In computational fluid dynamics (CFD), the numerical integration of the Navier-Stokes equations is frequently constrained by the Poisson equation to determine the pressure. Discretization of this equation often results in the need to solve a system o...
Operator dynamics in k-Markov random circuits
Unnati Akhouri, Pei-Jun Huang, Elliott Rose +1 more·Mar 18, 2026
We demonstrate that $k$-Markov sequences of unitary gates provide low-cost handles to manipulate the rate and structure of information spreading compared to traditional random, 0-Markov, circuits. For SWAP gates and brickwork circuits, we use graph c...

Gabriele Staffieri, Giuseppe D'Ambruoso, Giovanni Scala +1 more·Mar 18, 2026
It is known that preprocessing noise may boost quantum key distribution by expanding the range of values of tolerated noise. For BB84, adding trusted noise may allow the generation of secret keys even for qubit error rate (QBER) beyond the 11% thresh...
