Validation of an analyzability model for quantum software: a family of experiments
Ana Díaz-Muñoz, J. A. Cruz-Lemus, Moisés Rodríguez +2 more·Feb 20, 2026
The analyzability of hybrid software, which integrates both classical and quantum components, is a key factor in ensuring its maintainability and industrial adoption. This article presents the empirical validation, through a family of experiments, of...
Measuring and correcting nanosecond pulse distortions in quantum-dot spin qubits
Jiheng Duan, Fernando Torres-Leal, John M. Nichol·Feb 19, 2026
Gate-defined semiconductor quantum dots utilize fast electrical control to manipulate spin and charge states of individual electrons. Electrical pulse distortions can limit control fidelities but are difficult to measure at the device level. Here, we...
Quantum superresolution and noise spectroscopy with quantum computing
James W. Gardner, Federico Belliardo, Gideon Lee +2 more·Feb 19, 2026
Quantum metrology of an incoherent signal is a canonical sensing problem related to superresolution and noise spectroscopy. We show that quantum computing can accelerate searches for a weak incoherent signal when the signal and noise are not precisel...
Digital Quantum Simulation of the Holstein-Primakoff Transformation on Noisy Qubits
Kelvin Yip, Alessandro Monteros, Sahel Ashhab +1 more·Feb 19, 2026
Quantum simulation of many-body systems offers a powerful approach to exploring collective quantum dynamics beyond classical computational reach. Although spin and fermionic models have been extensively simulated on digital quantum computers, the sim...
Manipulating heterogeneous quantum resources over a network
Ray Ganardi, Jeongrak Son, Jakub Czartowski +2 more·Feb 19, 2026
Quantum information processing relies on a variety of resources, including entanglement, coherence, non-Gaussianity, and magic. In realistic settings, protocols run on networks of parties with heterogeneous local resource constraints, so different re...
Shortcuts to Adiabaticity via Adaptive Quantum Zeno Measurements
Adolfo del Campo·Feb 19, 2026
We consider the quantum Zeno dynamics arising from monitoring a time-dependent projector. Starting from a stroboscopic measurement protocol, it is shown that the effective Hamiltonian for Zeno dynamics involves a nonadiabatic geometric connection tha...
Vapor Phase Assembly of Molecular Emitter Crystals for Photonic Integrated Circuits
Arya D. Keni, Christian M. Lange, Adhyyan S. Mansukhani +6 more·Feb 19, 2026
Organic molecules embedded in an organic matrix exhibit lifetime-limited optical coherence and bright emission at cryogenic temperatures below 3 K. Here we present a simple vapor-phase growth method for synthesizing optically thin DBT-doped anthracen...
Detecting Initial System-Environment Correlations from a Single Observable
Ali Abu-Nada, Russell Ceballos, Lian-Ao Wu·Feb 19, 2026
We address the problem of detecting initial system--environment correlations when the environment is not directly accessible. Most existing approaches rely on full state tomography or multiple system preparations, which can be experimentally demandin...
Exact quantum decision diagrams with scaling guarantees for Clifford+$T$ circuits and beyond
Arend-Jan Quist, Tim Coopmans, Alfons Laarman·Feb 19, 2026
A decision diagram (DD) is a graph-like data structure for homomorphic compression of Boolean and pseudo-Boolean functions. Over the past decades, decision diagrams have been successfully applied to verification, linear algebra, stochastic reasoning,...
Topological Boundary Time Crystal Oscillations
Dominik Nemeth, Ahsan Nazir, Alessandro Principi +1 more·Feb 19, 2026
Boundary time crystals (BTCs) break time-translation symmetry and exhibit long-lived, robust oscillations insensitive to initial conditions. We show that collective spin BTCs can admit emergent topological winding numbers in operator space. Expanding...
Krylov Complexity, Confinement and Universality
Ali Fatemiabhari, Carlos Nunez·Feb 19, 2026
We perform a systematic holographic study of Krylov complexity for a wide class of confining quantum field theories. Using the geometric prescription that identifies the time derivative of the complexity with the proper momentum of a massive probe, w...
A Study of Entanglement and Ansatz Expressivity for the Transverse-Field Ising Model using Variational Quantum Eigensolver
Ashutosh P. Tripathi, Nilmani Mathur, Vikram Tripathi·Feb 19, 2026
The Variational Quantum Eigensolver (VQE) is a leading hybrid quantum-classical algorithm for simulating many-body systems in the NISQ era. Its effectiveness, however, depends on the faithful preparation of eigenstates, which becomes challenging in d...
Benchmarking quantum phase-space methods for near-resonant light propagation
Mojdeh S. Najafabadi, Joel F. Corney, Luis Sanchez Soto +1 more·Feb 19, 2026
We study the dynamics of light interacting with a near-resonant atomic medium using the truncated Wigner and positive P phase-space representations. The atomic degrees of freedom are described using the Jordan-Schwinger mapping. The dynamics is first...
Exotic critical states as fractional Fermi seas in the one-dimensional Bose gas
Alvise Bastianello, Yi Zeng, Sudipta Dhar +7 more·Feb 19, 2026
Critical quantum field theories occupy a central position in modern theoretical physics for their inherent universality stemming from long-range correlations. As an example, the Tomonaga-Luttinger liquid (TLL) describes a wealth of one-dimensional qu...
Approaching the Limit in Multiparameter AC Magnetometry with Quantum Control
Takuya Isogawa, Zhiyao Hu, Ayumi Kanamoto +9 more·Feb 19, 2026
Simultaneously estimating multiple parameters at the ultimate limit is a central challenge in quantum metrology, often hindered by inherent incompatibilities in optimal estimation strategies. At its most extreme, this incompatibility culminates in a ...
Pseudo-deterministic Quantum Algorithms
Hugo Aaronson, Tom Gur, Jiawei Li·Feb 19, 2026
We initiate a systematic study of pseudo-deterministic quantum algorithms. These are quantum algorithms that, for any input, output a canonical solution with high probability. Focusing on the query complexity model, our main contributions include the...
The Hidden Nature of Non-Markovianity
Jihong Cai, Advith Govindarajan, Marius Junge·Feb 19, 2026
The theory of open quantum systems served as a tool to prepare entanglement at the beginning stage of quantum technology and more recently provides an important tool for state preparation. Dynamics given by time dependent Lindbladians are Markovian a...
A Shadow Enhanced Greedy Quantum Eigensolver
Jona Erle, Balint Koczor·Feb 19, 2026
While ground-state preparation is expected to be a primary application of quantum computers, it is also an essential subroutine for many fault-tolerant algorithms. In early fault-tolerant regimes, logical measurements remain costly, motivating adapti...

Bojan Žunkovič, Marco Ballarin, Lewis Wright +1 more·Feb 19, 2026
We study an adiabatic variant of the variational quantum eigensolver (VQE) in which VQE is performed iteratively for a sequence of Hamiltonians along an adiabatic path. We derive the conditions under which gradient-based optimization successfully pre...
